Two-dimensional (2D) nanofluidic membranes hold great promise for osmotic energy conversion, yet achieving an optimal balance between ion permeability and selectivity remains a critical challenge. Herein, a spatially confined strategy was employed to in situ grow ZIF-8 nanoparticles and incorporate hydrophobic ionic liquid (HIL) [Bmim][NTf2] within a laminated graphene oxide (GO) membrane to form a GO/ZIF-8/[Bmim][NTf2] composite membrane with heterostructured nanochannels. The GO laminates serve as a robust scaffold for the whole system. The in situ growth of ZIF-8 enhances ion permeability and refines selectivity. The incorporation of HIL not only improves the membrane stability in aqueous electrolyte but also forms a continuous medium to optimize the ionic transport environment within the channels. Benefiting from this synergy, the resulting composite membrane achieves an excellent cation selectivity of 0.945 and a power density of 10.4 W m−2 under a 50-fold NaCl concentration gradient. This strategy is universal for the fabrication of different GO/MOF/HIL composite membranes (such as GO/HKUST-1/[Bmim][NTf2] and GO/ZIF-8/[Bmim][PF6]) and provides new insights into the design of high-performance 2D/MOF/HIL composite membranes for osmotic energy conversion.

MXenes are promising materials for energy storage due to their high electrical conductivity and unique layered structure. This study demonstrates the dual role of 1-Butyl-3-methylimidazolium tetrafluoroborate (BMImBF4) as both an etching agent and an intercalation medium for synthesizing Ti3C2Tx MXene with enhanced electrochemical performance. In-situ Raman and XRD analyses show that BMIm+ ions intercalate between MXene layers, stabilizing the nanoscale (002) interlayer spacing, preventing restacking and improving ion transport. When tested in the H2SO4–BMImBF4 hybrid electrolyte, the Ti3C2Tx MXene delivers a capacitance of 228.7 F g–1 at a scan rate of 1 mV s–1, compared to 179.9 F g–1 in pure H2SO4, measured on the same batch of materials. This demonstrates that incorporating BMImBF4 into H2SO4 significantly enhances the charge storage capability of Ti3C2Tx MXene. These findings highlight the effectiveness of BMImBF4 in optimizing charge storage and reinforce the potential of ionic liquids for advanced MXene-based energy storage systems.

Imidazolium salts containing , , , , or ionic liquids were blended with an epoxy prepolymer, dyglycidylether of bisphenol A (DGEBA) to obtain a series of compositions. To characterize the resulting mixtures and determine the influence of the imidazolium anion on the reactivity and properties of epoxy systems, we performed the following analyses and tests: (i) differential scanning calorimetry (DSC), to determine the curing reaction characteristics, (ii) in situ fourier-transform infrared spectroscopy (FTIR), to assess chemical structure changes, (iii) mechanical property testing of the hardened epoxy material, and (iv) thermogravimetric analysis (TGA). The DSC and FTIR analyses indicate that [Hmim]BF4, and [Hmim]PF6 cannot induce the epoxy ring opening reaction and thus these materials are unable to function as epoxy curing agents. In contrast, the imidazolium ionic liquids [Hmim]FeCl4, [Hmim]N(CN)2, and [Hmim]Zn2Cl5 independently promote the epoxy ring opening reaction. TGA analyses show that the cured DGEBA/[Hmim]Zn2Cl5 system exhibits thermal stability similar to the cured DGEBA/[Hmim]FeCl4. These results can provide an essential reference not only for studying the synergistic effect of [C6mim]FeCl4/mixed-amines on the curing process of epoxy systems and the mechanism of the ring opening of epoxides with [C6mim]FeCl4/mixed-amines, but also for designing new epoxy curing systems.

Superior to conventional liquid electrolytes , incombustible ionic liquids (ILs) with wide electrochemical stability windows show privilege to endow quasi-solid-state electrolyte (QSE) with benign interfacial contact with both metallic Li and high-voltage cathode, which bodes well for implementation of high-performance solid-state Li metal battery . But regardless of its merits, the inherent high-viscosity and frail interphase chemistry of IL towards cathodes still jeopardize ionic conductivity within QSE and even crossing the interface, and should be overcame. Herein, we creatively introduce N, N -Dimethyltrifluoroacetamide (FDMAC) into QSE fabrication, design a quasi-solid-state electrolyte (QSE-EF) by hybridizing FDMAC/EMImFSI-based IL mixture and nano-LLZTO@PVDF-HFP. This FDMAC with well compatibility to IL, significantly decreases the viscosity but without sacrificing noncombustible feature. With the aid of FDMAC, QSE-EF exhibits fast ion-conducting and high Li + transference number. More importantly, FDMAC also contributes to tuning interphase chemistry, and therefore, the high compatibilities of both QSE-EF | Li and QSE-EF | NCM622 interfaces are fulfilled involving profitable CEI&SEI establishment. Consequently, the assembled NCM622 | QSE-EF | Li cell delivers outstanding electrochemical behaviors even at 4.4 V high voltage. 1.0 Ah NCM811ǁLi pouch cell also shows satisfactory energy density (350 Wh·kg −1 ) with negligible capacity loss. This work provides a feasible strategy to circumvent inherent defect of ionic liquid in QSE, and emphasizes the importance of tuning compatible interfacial chemistry in further QSE design.

In our work, we achieve the multi-component assembly of novel kinds of photofunctional hybrid materials with polyoxometalates (POMs, Na 9 EuW 10 O 36 ·32H 2 O (EuW 10 O 36 9 - denoted as EuW10)) and benzoate (4-aminobenzoate, 4-hydroxybenzoate, 4-mercaptobenzoate) modified mesoporous silica through imidazolium ionic liquid (IL, 1-methyl-3-(trimethoxysilylpropyl) compound as double functional linkage. Using Pluronic P123 surfactant as a template, benzoate functionalized SBA-15 mesoporous host is synthesized as result of the co-condensation of tetraethoxysilane (TEOS) and benzoate modified siloxane as precursor. We fabricate POM into the framework of functionalized SBA-15 mesoporous silica with IL. Here IL behaves as double linkage, which both interact with PMO with electrostatic force through ion exchange and form covalent bond to the functionalized SBA-15 mesoporous silica through its alkoxy group after cohydroxylysis and copolycondensation process. Tb 3+ is further introduced into the above hybrid system through coordination bond to carboxylate group of benzoate unit, which can be expected to modify luminescence color and to obtain close white luminescence. The physical characterizations prove these hybrid materials possess high surface area, uniform mesoporous structure, good crystallization and relatively excellent luminescence properties.

Droplet size distribution (DSD) and mean droplet size of chloroaluminate ionic liquid (IL)–heptane dispersion in a stirred vessel were investigated as a model system for the composite ionic liquid/hydrocarbon system applied in the commercial isobutane alkylation process. Focused beam reflectance measurement was used to identify the phase inversion, and particle video microscope (PVM) was employed to measure the DSD of IL-continuous dispersions. The effects of agitation speed and dispersed phase holdup on the DSD and mean droplet size were investigated. Phase inversion was found at a heptane hold-up of just above 0.5. The observed DSDs could be described well by logarithmic normal distributions in spite of variable operating conditions. The DSDs appeared to be more or less independent of the dispersed phase holdup ( ϕ heptane ⩾ 0.3) at the same agitation speed. A semi-empirical correlation based on Shinnar theory was proposed to predict the droplet mean size in the impeller region for the IL-continuous dispersion, and the predicted value agreed well with the experimental data. This work will be a good basis to predict the dispersion behavior under process conditions.

Poly (ionic liquid)s are an emerging family of promising polymer electrolytes . In this study, a nanocomposite electrolyte based on ice-templated high-graphene oxide-loading poly (ionic liquid) (GO/PIL) was prepared to significantly improve ion transport of PIL. X-ray diffraction patterns exhibited that GO was well-loaded in the as-prepared composites event at high content of 50 wt%. The Raman and UV–Vis spectra demonstrated the strong interaction between GO and PIL. Morphology observations showed that PIL could well contact with GO, forming so-called "PIL&GO nanosheets" that were connected in an ionic-conducting network, which facilitated the ion transport in the PIL, as revealed by conductive atomic force microscope investigation. As a result, with a superhighway for ions built, PIL-based composite electrolyte obtained a higher ionic conductivity of 3.1 × 10 −4 S cm −1 at 50 wt% GO, 775% of that of pure PIL electrolyte. Such ice-templated nanocomposite electrolytes possess potential applications for various electrochemical devices .

This study successfully prepared a porous spherical PBAT-g-IL/MMT composite adsorbent (PIMMT) for treating toxic, refractory dye wastewater through a one-step melt blending process combined with non-solvent-induced phase separation. Ionic liquids perform a dual function in this process. ILs enhance PBAT hydrophilicity through radical grafting and form intercalation structures with MMT via ion exchange, providing rapid transport pathways for pollutant molecules. This research aims to develop a biodegradable adsorbent material that combines highly efficient adsorption performance, good hydrophilicity and structural tunability. The effects of initial dye concentration, pH, temperature, contact time, and adsorbent dosage were systematically investigated. Under optimal conditions, the best sample PIMMT8 demonstrated high removal efficiency for cationic dyes methylene blue (MeB) and auramine O (AO), achieving maximum adsorption capacities (Q max ) of 145.85 mg g −1 and 191.07 mg g −1 respectively. Adsorption kinetics conformed to the pseudo-second-order model (R 2 > 0.99), while isotherm data better aligned with the Freundlich model (R 2 > 0.99), indicating multi-layer adsorption. The adsorbent demonstrated excellent reusability, maintaining removal efficiencies above 85 % for both MeB and AO after six adsorption-desorption cycles. Furthermore, the study innovatively employed a combined alcohol-alkali hydrolysis process to achieve resource recovery of the adsorbent, successfully recovering monomers such as terephthalic acid and adipic acid. This research not only fills a gap in the study of PBAT/MMT composites for dye adsorption but also provides novel insights for designing wastewater treatment materials that combine high adsorption efficiency, environmental friendliness, and resource recycling properties.

Staphylococcus aureus membrane vesicles (MVs) cause host injury and excessive inflammation, yet their pathological roles and clearance strategies remain undefined. Guided by molecular dynamics simulations of MV-polymer interactions, we engineered imidazolium-based poly(ionic liquid) (PIL) electrospun nanofibers for targeted MV interception. Among multiple formulations, PIL-C4 demonstrated optimal performance, combining potent antibacterial activity, robust adsorption of methicillin-resistant S. aureus (MRSA) MVs and their virulence factors, minimal cytotoxicity, and inhibition of resistance transmission. In vivo, PIL-C4 attenuated MV-induced neutrophil extracellular trap (NET) formation (NETosis) and vascular leakage, thereby reducing purulent-exudative wound injury and preventing systemic organ damage, including fatal lung injury. Notably, DNase-mediated NET degradation alone failed to rescue MV pathology, underscoring the necessity of direct MV clearance. This study uncovers previously unrecognized NETosis-driven phenotypes of S. aureus MVs—local purulent-exudative wound injury and systemic lethal lung damage—and establishes a polymer-based clearance strategy with translational potential for infection control.

To overcome the limitations of conventional ionic liquid-based CO 2 absorbents—namely high regeneration energy consumption and low absorption capacity—a novel biphasic dual-functionalized ionic liquid system, [AEPH][Im]/NPA/H 2 O, was synthesized and evaluated. Initially homogeneous, the system undergoes spontaneous phase separation upon CO 2 absorption, forming distinct lean and rich phases. At saturation, the rich phase accounted for 53.00% of the total volume, with a viscosity of 15.75 mPa·s and a CO 2 loading capacity of 3.43 mol·L −1 . The system exhibited a high regeneration efficiency of 83.42% at 393.15 K, and the regenerated phases could be recombined into a uniform solution. After six absorption-desorption cycles, the absorbent retained 96.39% of its initial capacity, with only a 1.32% decline in desorption efficiency. The 13 C NMR analysis and DFT calculations revealed that CO 2 primarily reacts with [AEPH][Im] to form carbamate, carbonate, and bicarbonate species, which are predominantly concentrated in the rich phase, while only unreacted components remain in the lean phase. NPA facilitates the formation of alkyl carbonates via reaction with carbamates, and the high concentration of bicarbonate significantly enhanced desorption efficiency. The total regeneration energy consumption was calculated to be as low as 1.58 GJ·t −1 CO 2 —markedly lower than that of traditional MEA-based solvents. The [AEPH][Im]/NPA/H 2 O biphasic system demonstrates superior cyclic stability, high CO 2 capture capacity, and low energy demand, presenting a promising alternative for industrial-scale carbon capture applications.

Efficient and low-energy absorbents are always desirable to control the greenhouse effect. In this study, a novel amino polycarboxylate ionic liquid absorbent is constructed by introducing carboxylate groups. The CO 2 absorption-desorption experiments in microchannel and macroscopic devices are performed to comprehensively investigate the performance of choline iminodiacetate ([Ch] 2 [IDA]). It is found that [Ch] 2 [IDA] could form soluble carbamic acid upon CO 2 absorption, thereby effectively preventing equipment blocking compared to choline glycine ([Ch][Gly]). The dual carboxyl groups in [IDA] 2− could generate a synergistic effect to weaken the negative inductive action of the amino group; consequently, [Ch] 2 [IDA] displays superior CO 2 absorption performance over [Ch][Gly]. Furthermore, [Ch] 2 [IDA] aqueous solution could release more CO 2 in the rapid desorption stage and effectively alleviate the sharp increase of energy consumption during the desorption termination period. Especially, it exhibits excellent cycling stability. Comparatively, [Ch] 2 [IDA] aqueous solution demonstrates great potential as a next-generation efficient and low-energy CO 2 absorbent.

Colorimetric detection of trace Hg 2+ relies primarily on enzymes -catalyzed 3,3’,5,5’-tetramethylbenzidine (TMB) reactions, with two inherent drawbacks: substrate solubilization dependence on organic solvents and enzymes-associated limitations. By virtue of unique structural tunability and ionic properties, ionic liquids (ILs) dual-substitute enzymes and organic solvents, breaking through traditional bottlenecks via electrostatic assistance. Specifically, ILs enhance TMB water solubility efficiently through π-π interaction/charge-assisted hydrogen bond (CAHB) synergy, thus obviating organic solvents; meanwhile, CAHB and electrostatic interactions accelerate TMB-Hg 2+ redox reactions, eliminating exogenous H 2 O 2 and enzymes s and cutting response equilibrium time by ~35 min. Experiments confirmed that vs. CAHB-free blank systems shows a 2.2-fold increase in absorbance. Moreover, the system exhibits robust anti-interference, maintaining high sensitivity and stability across the pH range of 4.0–6.0. The paper-based ILs sensor allows naked-eye, on-site detection of trace Hg 2+ efficiently.
