Emulsification is one of the important mechanisms of surfactant flooding. To improve oil recovery for low permeability reservoirs, a highly efficient emulsification oil flooding system consisting of anionic surfactant sodium alkyl glucosyl hydroxypropyl sulfonate(APGSHS) and zwitterionic surfactant octadecyl betaine(BS-18) is proposed. The performance of APGSHS/BS-18 mixed surfactant system was evaluated in terms of interfacial tension, emulsification capability, emulsion size and distribution, wettability alteration, temperature-resistance and salt-resistance. The emulsification speed was used to evaluate the emulsification ability of surfactant systems, and the results show that mixed surfactant systems can completely emulsify the crude oil into emulsions droplets even under low energy conditions. Meanwhile,the system exhibits good temperature and salt resistance. Finally, the best oil recovery of 25.45% is achieved for low permeability core by the mixed surfactant system with a total concentration of 0.3 wt%while the molar ratio of APGSHS:BS-18 is 4:6. The current study indicates that the anionic/zwitterionic mixed surfactant system can improve the oil flooding efficiency and is potential candidate for application in low permeability reservoirs. 展开更多

Zwitterionic materials with covalently tethered cations and anions have great potential as electrolyte additives for aqueous Znion batteries(AZIBs)owing to their appealing intrinsic characteristics and merits.However,the impact of cationic and anionic moieties within zwitterions on enhancing the performance of AZIBs remains poorly understood.Herein,three zwitterions,namely carboxybetaine methacrylate(CBMA),sulfobetaine methacrylate(SBMA),and 2-methacryloyloxyethyl phosphorylcholine(MPC),were selected as additives to investigate their different action mechanisms in AZIBs.All three zwitterions have the same quaternary ammonium as the positively charged group,but having different negatively charged segments,i.e.,carboxylate,sulfonate,and phosphate for CBMA,SBMA,and MPC,respectively.By systematical electrochemical analysis,these zwitterions all contribute to enhanced cycling life of Zn anode,with MPC having the most pronounced effect,which can be attributed to the synergistic effect of positively quaternary ammonium group and unique negatively phosphate groups.As a result,the Zn//Zn cell with MPC as additive in ZnSO4electrolyte exhibits an ultralong lifespan over 5000 h.This work proposes new insights to the future development of multifunctional zwitterionic additives for remarkably stable AZIBs. 展开更多

Specific anion exchange membranes(AEMs)are vital to highly efficient electrochemical CO2reduction(ECR),which is a promising choice for carbon neutrality.However,the unexpected trade-off effect originating from the ion conductivity and the hydrogen evolution reaction(HER)is still a great challenge.Herein,AEMs with hydrophobic clusters distribution in hydrophilic domain were designed and prepared by special ternary-polymerization polybenzimidazole(TP-PBI).The hydrophilic domain contributed to high ionic conductivity and dispersed hydrophobic clusters inhibited the membrane swelling and consequently the HER.As a result,an increase of 157%was achieved in ionic conductivity compared with that of OPBI and the prepared TP-PBI membranes exhibit CO Faradaic efficiency(FEco)as high as 96.2%,outstanding in situ durability for 24 h at 100 mA cm-2.Such TP-PBI membranes throw new light on the development of AEMs for highly efficient ECR. 展开更多

Developing advanced ion-conductive networks is crucial for anion exchange membranes(AEMs).A flexible molecular structure facilitates the formation of ion clusters,resulting in enhanced ionic conductivity.Polyacrylates,known for their outstanding flexibility and chemical stability,hold significant potential as polymer electrolyte membranes.In this work,we innovatively constructed a series of polyacrylate-based AEMs decorated with pendant zwitterions(designated as PSBPA-X,BSBPA-X,where X=20,30,40).Specifically,the spacer length between the zwitterions is strategically optimized to enhance the ionic conductivity.Atomic force microscopy reveals that a longer spacer length between the zwitterions promotes the microphase separation and the formation of advanced water channels,which facilitates the OH-transport in the BSBPA-40 membrane.Moreover,the stronger electrostatic potential and lower interaction energy between the BSBPA-40 and OH-further contribute to efficient OH-hopping transmission.Consequently,the BSBPA-40 membrane demonstrates the highest OH-conductivity,achieving 102.1 mS cm-1at 80℃ and 90% relative humidity,significantly surpassing that of the PSBPA-40 membrane(75.2 mS cm-1).Additionally,the BSBPA-40 membrane exhibits remarkable flexibility with an improved breaking elongation of 480.5%due to the ionic cross-linking between the zwitterions.Notably,the BSBPA-40 membrane-based zinc-air battery achieves an outstanding power density of 156.7 mW cm-2at room temperature,while its water electrolysis performance reaches 2.1 A cm-2at 2.0 V.These results indicate that the developed membranes hold great promise for applications in sustainable and clean energy technologies. 展开更多

Water-based lubrication systems incorporating nanoparticles as highly promising additives are ofgreat importance for enabling sustainable and environmentally benign tribologicalsolutions.However,persistent limitations encompass pronounced substrate dependence,inadequate dynamic responsiveness under operating conditions,and intrinsically constrained lubrication performance,collectively impeding their transition from laboratory potential to robust industrial deployment.To tackle these challenges,we have developed a substrate-adaptable and dual-responsivelysine-based surfactant(LBS)as a cutting-edge water-based lubrication additive.LBS achieves substrate-independent adsorption through multiple interactions between its head group and substrates of varying properties.LBS maintains consistent lubrication performance with minimal COF variation across substrates with divergent surface charges,confirming its adaptability to diverse tribological substrates.Notably,the engineered surfactant demonstrates outstandinglubricating properties,achieving a coefficient of friction(COF)of~0.06 under extreme pressure condition(~500 MPa),a 95%reduction in COF compared to pure water and maintaining stable lubrication over 25,000 cycles without significant wear or interfacial degradation.Additionally,byleveraging the pH sensitivity of the molecular structure and the temperature responsiveness of the micellar assembly,the COF can be rapidly modulated over a 10-fold range in response by changes pH and temperature.By synergistically integrating universal substrate adaptability with stimuli-responsive behavior,this work not only ensures stable lubrication in complex substrates,but also opens new avenues for theintelligent design of surfactants,offering significant potential for large-scale applications in intelligent lubrication. 展开更多

Rechargeable aqueous zinc-iodine(Zn-I2)batteries demonstrate enhanced specific capacity,cycle performance,and reduced costs when compared to other zinc-based batteries.However,their practical application is limited by the flagrant parasitic reactions generated at the Zn anode and the I2cathode,leading to compromised electrochemical properties.In this study,zwitterionic propane sulfonic pyridine(PPS)molecules,containing sulfonate-anionic and pyridine N-cationic groups,are introduced as dual-functional electrolyte additives in Zn-I2batteries to regulate the interfacial chemical environment.At the Zn anode,the sulfonate-anionic group in PPS strongly adsorbs onto the Zn(002)surface,forming a zincophilic-hydrophobic buffer layer that enhances Zn2+deposition kinetics and suppresses side reactions such as the hydrogen evolution reaction(HER)and Zn corrosion.Moreover,the lone pair electrons on the pyridine-N atom interact with H+and OH-species,thereby buffering pH fluctuations near the Zn anode and preventing corrosion.At the I2cathode,PPS-induced reconfiguration of iodide-ion solvation impairs interfacial reactions associated with I2dissolution and polyiodide formation.Besides,ion-dipole interactions between pyridine-N groups and polyiodides also confine polyiodides,thereby mitigating the shuttle effect.Consequently,this zwitterionic additive enables a Zn//Zn symmetric cell to cycle stably for 2250 h at 5 mA cm-2,and the Zn-I2battery to achieve an ultra-long lifespan exceeding 65,000 cycles.These findings deepen the understanding of the mechanism of zwitterionic additives on Zn-I2battery and set the groundwork for the enhancement of their practical application. 展开更多

Gel-based flexible wearable sensors have attracted considerable interest in aquatic environments.However,the development of underwater conductive gel sensors with outstanding anti-swelling,mechanical,and sensing capabilities faces significant challenges.The aim of this study is to develop anti-swelling and conductive zwitterionic gels and investigate their applications in wireless underwater strain sensing.Multi-functional zwitterionic gels were fabricated by copolymerizing[2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide(SBMA)and acrylic acid(AA)in a mixed solution of aluminum chloride(AlCl3)and poly(vinyl alcohol)(PVA)under ultraviolet light(360 nm).PSBMA was switched from a neutral polymer to a positively charged polymer because of the combination of Al3+with the negative groups SO3−.The water molecules were eliminated because of electrostatic repulsion.The gels exhibited anti-swelling properties(swelling ratio98.9%inhibition)and stable wireless sensing have potential applications in the fields of wearable sensors,underwater communication,and intelligent healthcare. 展开更多

Localized high-concentration electrolytes(LHCEs)are considered as promising electrolyte candidates to resolve technical issues of metal batteries owing to their unique interfacial properties and solvation structures.Herein,we propose a self-assembly chemical strategy into the LCHEs induced by ordered nanostructure of zwitterionic co-solutes for highly efficient and ultrastable zinc(Zn)metal batteries.Through the systematic screening of six zwitterionic compounds,3-(decyldimethylammonio)propanesulfonate salt(C10)with the decyl chain and zwitterions was determined as an optimum to construct quasi-spherical aggregates with a periodic length of 3.77 nm,as confirmed by comprehensive synchronous small-angle X-ray scattering,Guinier,pair distance distribution function,Porod,and other spectroscopic characterizations and molecular dynamic simulation.In particularly,this self-assembled structure in electrolyte environments was attributed to increasing the proportion of both contact and aggregated ion pairs for the formation of LHCEs as well as to providing fast and selective Zn2+conducting channels and uniform solid electrolyte interfaces for facilitated charge transfer kinetics.Moreover,the preferential adsorption of the self-assembled C10on the Zn(002)surface modulated the electrical double layer to suppress hydrogen evolution and corrosion reactions.Consequently,the Zn‖Zn symmetric cells in Zn(OTf)2/C10electrolytes showed long-term plating/stripping behaviors over 2800 h at 1 mA cm-2and 1 mAh cm-2as well as over 1200 h even at 5 mA cm-2and 5 mAh cm-2with a very high depth of discharge of 42.7%.Furthermore,the ZnllVO2/CNT full cells in Zn(OTf)2/C10electrolytes delivered a record-high capacity of 8.10 mAh cm-2at an ultrahigh cathode mass loading of 50 mg cm-2after 150 cycles. 展开更多

An effective strategy for enhancing the heat resistance of polystyrene(PS)with regard to its glass transition temperature(Tg)involves the anionic solution copolymerization of a-methylstyrene(AMS)with styrene(St),typically requires much lower temperature(-25℃)and multistep monomer feeding to achieve higher number-average molecular weight(Mn)block copolymers.However,the anionic copolymerization of AMS and St under the mild temperature remains largely unexplored.This study systematically investigated the anionic copolymerization of AMS and St using n-BuLi in nonpolar solvent(-25℃ to 25℃)through both one-step and two-step approaches.We demonstrated that one-step copolymerization at 25℃ yielded only 1-3 terminal AMS units,with higher feed ratios(5 wt%-20 wt%)increasing AMS incorporation but reducing the exact molecular weight(MW)due to enhanced depolymerization,as evidenced by MALDI-TOF MS.Temperature-controlled AMS conversion at-15℃ achieved 98%AMS conversion(5 wt% feed)by suppressing side reactions and lowering the[M]e,while 50℃(near TC)almost prevented incorporation.Despite t-BuOK regulation induced broader PDI(1.24)via reactive[(polymer-Li)OR]K intermediates,while other systems showed narrow distributions,t-BuOK outperformed THF in enhancing AMS incorporation via efficient ion pair dissociation.In comparison,the two-step polymerization approach demonstrated superior performance,achieving both higher AMS conversion efficiency and preferential incorporation at the initiation end.At a 20 wt%AMS feed ratio,this method yielded copolymer chains containing up to 6 AMS units on average.Thermal analysis revealed a composition-dependent single Tg,which exhibited a systematic increase with higher AMS incorporation content.These results collectively demonstrate the precise control over AMS incorporation and heat resistance achievable through the manipulation of polymerization conditions. 展开更多

The sluggish Li+migration kinetics and unstable electrode/electrolyte interface severely hinder the commercial application of high-performance lithium metal batteries(LMBs).Herein,an artificial protective layer is constructed using zwitterionic covalent organic framework(Z-COF)simultaneously containing sulfonate and ethidium groups,aiming to facilitate rapid,uniform Li+transport and stabilize anode interface.The sulfonate groups with high lithiophilicity provide abundant hopping sites for fast Li+diffusion.The ethidium cations immobilize TFSI-and solvent molecules by ion-dipole interactions,which accelerate the dissociation of LiTFSI and Li+desolvation.Moreover,the monodispersed zwitterionic units coupling with ordered micropore structures in Z-COF create exclusive Li+migration channels,modulate homogeneous space charge distribution,kinetically facilitating uniform Li+deposition.Experiments and theoretical calculations indicate that C-F and S-N bonds of TFSI-exhibit enhanced cleavage susceptibility driven by electrostatic attraction,realizing a LiF/Li3N-rich electrolyte/electrode interface.The designed Z-COF protection layer enables Li|Li symmetrical cells stable cycling over 6300 h at 2 mA cm-2/2 mAh cm-2.The Z-COF@Li|LiFePO4(LFP)full cells deliver high-capacity retention of 85.2%after 1000 cycles at 8 C.The assembled Z-COF@Li|LFP pouch cells demonstrate a lifespan of more than 240 cycles.This work provides fresh insights into the practical application of zwitterionic COF in next-generation LMBs. 展开更多

Solar-driven interfacial desalination(SID)offers a sustainable route for freshwater production,yet its long-term performance is compromised by salt crystallization and microbial fouling under complex marine conditions.Zwitterionic polymers offer promising nonfouling capabilities,but current zwitterionic hydrogel-based solar evaporators(HSEs)suffer from inadequate hydration and salt vulnerability.Inspired by the natural marine environmental adaptive characteristics of saltwater fish,we report a superhydrated zwitterionic poly(trimethylamine N-oxide,PTMAO)/polyacrylamide(PAAm)/polypyrrole(PPy)hydrogel(PTAP)with dedicated water channels for efficient,durable,and nonfouling SID.The directly linked N⁺and O⁻groups in PTMAO establish a robust hydration shell that facilitates rapid water transport while resisting salt and microbial adhesion.Integrated PAAm and PPy networks enhance mechanical strength and photothermal conversion.PTAP achieves a high evaporation rate of 2.35 kg m−2h−1under 1 kW m–2in 10 wt%NaCl solution,maintaining stable operation over 100 h without salt accumulation.Furthermore,PTAP effectively resists various foulants including proteins,bacterial,and algal adhesion.Molecular dynamics simulations reveal that the exceptional hydration capacity supports its nonfouling properties.This work advances the development of nonfouling HSEs for sustainable solar desalination in real-world marine environments. 展开更多

Flexible strain sensors have received tremendous attention because of their potential applications as wearable sensing devices.However, the integration of key functions into a single sensor, such as high stretchability, low hysteresis, self-adhesion, andexcellent antifreezing performance, remains an unmet challenge. In this respect, zwitterionic hydrogels have emerged asideal material candidates for breaking through the above dilemma. The mechanical properties of most reported zwitterionichydrogels, however, are relatively poor, significantly restricting their use under load-bearing conditions. Traditional improve-ment approaches often involve complex preparation processes, making large-scale production challenging. Additionally,zwitterionic hydrogels prepared with chemical crosslinkers are typically fragile and prone to irreversible deformation underlarge strains, resulting in the slow recovery of structure and function. To fundamentally enhance the mechanical properties ofpure zwitterionic hydrogels, the most effective approach is the regulation of the chemical structure of zwitterionic monomersthrough a targeted design strategy. This study employed a novel zwitterionic monomer carboxybetaine urethane acrylate(CBUTA), which contained one urethane group and one carboxybetaine group on its side chain. Through the direct polym-erization of ultrahigh concentration monomer solutions without adding any chemical crosslinker, we successfully developedpure zwitterionic supramolecular hydrogels with significantly enhanced mechanical properties, self-adhesive behavior, andantifreezing performance. Most importantly, the resultant zwitterionic hydrogels exhibited high tensile strength and tough-ness and displayed ultralow hysteresis under strain conditions up to 1100%. This outstanding performance was attributedto the unique liquid–liquid phase separation phenomenon induced by the ultrahigh concentration of CBUTA monomers inan aqueous solution, as well as the enhanced polymer chain entanglement and the strong hydrogen bonds between urethanegroups on the side chains. The potential application of hydrogels in strain sensors and high-performance triboelectric nano-generators was further explored. Overall, this work provides a promising strategy for developing pure zwitterionic hydrogelsfor flexible strain sensors and self-powered electronic devices. 展开更多

As the global exploration and development of oil and gas resources advances into deep formations,the harsh conditions of high temperature and high salinity present significant challenges for drilling fluids.In order to address the technical difficulties associated with the failure of filtrate loss reducers under high-temperature and high-salinity conditions.In this study,a hydrophobic zwitterionic filtrate loss reducer(PDA)was synthesized based on N,N-dimethylacrylamide(DMAA),2-acrylamido-2-methylpropane sulfonic acid(AMPS),diallyl dimethyl ammonium chloride(DMDAAC),styrene(ST)and a specialty vinyl monomer(A1).When the concentration of PDA was 3%,the FLAPI of PDA-WBDF was 9.8 mL and the FLHTHP(180℃,3.5 MPa)was 37.8 mL after aging at 240℃for 16 h.In the saturated NaCl environment,the FLAPI of PDA-SWBDF was 4.0 mL and the FLHTHP(180℃,3.5 MPa)was 32.0 mL after aging at 220℃ for 16 h.Under high-temperature and high-salinity conditions,the combined effect of anti-polyelectrolyte and hydrophobic association allowed PDA to adsorb on the bentonite surface tightly.The sulfonic acid groups of PDA increased the negative electronegativity and the hydration film thickness on bentonite surface,which enhanced the colloidal stability,maintained the flattened lamellar structure of bentonite and formed an appropriate particle size distribution,resulting in the formation of dense mud cakes and reducing the filtration loss effectively. 展开更多

Zwitterionic polymers are polymers containing a pair of oppositely charged groups in their repeating units,which facilitate the formation of a hydration layer on the surface through ionic solvation.This strong hydration results in the remarkable properties of zwitterionic polymer hydrogels,including antifouling,lubricating,and anti-freezing capabilities.Owing to these properties,zwitterionic polymer hydrogels have attracted notable attention in biomedical and engineering fields.However,the superhydrophilicity of zwitterionic polymer hydrogels renders them brittle and weak,considerably limiting their use in load-bearing applications.Thus,there is an urgent need to improve the mechanical properties of zwitterionic hydrogels.In this work,we systematically review mechanical enhancement strategies for zwitterionic polymer hydrogels.We cover strate-gies applicable to hybrid and pure high-strength zwitterionic polymer hydrogels.Additionally,we discuss the advantages and limitations of various strength enhancement strategies. 展开更多

Na3V2(PO4)2O2F (VP) is recognized as a promising cathode material for sodium-ion batteries due to its stable structural framework and high specific capacity.Density functional theory (DFT) and finite element simulations show that incorporating SO42-into VP decreases its band gap,lowers the migration energy barrier,and ensures a uniform Na+concentration gradient and stress distribution during charge and discharge cycles.Consequently,the average Na+diffusion coefficient of Na3V2(PO4)1.95(SO4)0.05O2F(VPS-1) is roughly double that of VP,leading to enhanced rate capability (80 C,75.5 mAh g-1) and cycling stability (111.0 mAh g-1capacity after 1000 cycles at 10 C current density) for VPS-1.VPS-1 exhibits outstanding fast-charging capabilities,achieving an 80%state of charge in just 8.1 min.The assembled VPS-1//SbSn/NPC full cell demonstrated stable cycling over 200 cycles at a high 5 C current,maintaining an average coulombic efficiency of 95.35%. 展开更多

Zwitterions(ZIs)are considered as an ideal,novel ionic conductive medium due to their high dipole moment and good solubility of lithium salts.However,the strong interactions between ZIs and Li+severely hinder Li+migration.Herein,a quasi-solid electrolyte(MSQSE-2Na)was fabricated by adding sodium bis(fluorosulfonyl)imide(NaFSI)to sulfobetaine methacrylate(SBMA,a ZI)based polymerization system.Na+occupies the–SO3-site in SBMA prior to Li+,which weakens the self-crosslinking of SBMA and frees the Li+bound to the polymer segments.Thus,the polymer conformation of MSQSE-2Na changes to a relaxed,homogeneous"sea-island"type.Meanwhile,Na+,due to its electron-withdrawing effect,decreases the electron cloud density of the polymer segments,building a weakly coordinated environment in MSQSE-2Na.Consequently,MSQSE-2Na exhibits excellent ionic conductivity of 7.38×10-4S cm-1and a high Li+transference number of 0.632 at 25℃.The(-)Li|MSQSE-2Na|Li(+)cells exhibit super stability,sustaining operation for over 6182h.The(-)Li|MSQSE-2Na|LiFePO4(+)cells demonstrate outstanding charge/discharge reversibility with a Coulombic efficiency exceeding 99.9%over 270 cycles(≈4500 h),with a capacity retention of 70.0%.This work proposes a new design concept for regulating the polymer conformation and charge characteristics through competitive coordination,thereby advancing the application of ZI-based polymer electrolytes in lithium metal batteries. 展开更多

Lysozyme,myoglobin and BSA were used as models of globular proteins covering a wide range of pl.The purpose is to extend the studies to anionic lipid bilayers.Electrostatics is studied in cationic protein adsorption to zwitterionic PC and anionic mixed PC/PG SUVs.Protein adsorption is investigated in SUVs along with changes of fluorescence emission spectra.Partition coefficients and cooperativity parameters are calculated.At pl binding obtains maximum while at lower or higher pHs binding decreases.In Gouy-Chapman formalism activity coefficient goes with square charge,which deviations indicate asymmetric location of anionic phospholipid in the inner leaflet,in mixed SUVs for lysozyme-and myoglobin-PC/PG systems,in agreement with experiments and molecular dynamics simulations.Vesicles bind myoglobin anti-cooperatively while lysozyme-BSA cooperativitivey.A model is proposed for both,which composes two protein sub-layers with different structures and properties.Hill coefficient reflects subunit cooperativity of bi and tridomain proteins. 展开更多

The objective of this study was to predict,screen,synthesize,and investigate cocrystals of poorly soluble flavonoids that are commonly found in dietary supplements with bipolar compound picolinic acid(PA).To improve the efficiency and success rate of experimental screening,two virtual tools based on hydrogen bond propensity(HBP)and modified molecular electrostatic potential(MEP)maps were used.The prediction accuracy of HBP and MEP is 58.82%and 94.11%,respectively,presenting that the MEP model is very powerful in the discovery of pharmaceutical cocrystals.Among the 12 successfully obtained cocrystals,4 single crystals of PA with luteolin(LUT),genistein(GEN),taxifolin(TAX),dihydromyricetin(DHM)were obtained for the first time.Charged-assisted O-H…O and N-H…O hydrogen bonds appear as main hydrogen bonding synthons,and PA adopts a zwitterionic form after cocrystallization.GEN-PA,TAX-PA,and DHM-PA showed higher DPPH'radical-scavenging capacities;LUT-PA and DHM-PA showed higher ABTS+radical-scavenging capacities;GEN-PA and DHM-PA possessed better protective effects on H9c2 cells from hypoxic injury caused by CoCl2than corresponding pure flavonoids. 展开更多
