Aqueous lithium‐ion batteries (ALIBs) often suffer from water crystallization and suppressed ionic transport under subzero conditions as well as narrow electrochemical stability windows. Here, we report a hybrid electrolyte based on 1 M LiNO 3 in [EMIM][DEP] 0.1 ‐(H 2 O) 0.9 that combines the non‐flammability of ionic liquids with the high ionic conductivity of water. Strong [DEP]‐(H 2 O) hydrogen bonding disrupts the water network, lowering the freezing point from −24°C to −56°C while maintaining an ionic conductivity of 1.295 × 10 −3 S cm −1 at −35°C. Meanwhile, ionic‐liquid enrichment at the anode forms a water‐restricted interphase that widens the apparent electrochemical stability window from 1.4 to 2.15 V, as supported by experimental characterization and molecular dynamic simulations. In a LiMn 2 O 4 /LiTi 2 (PO 4 ) 3 full cell, this hybrid electrolyte delivers 90 mAh g −1 at −35°C and 0.2 C and retains 90% of its initial capacity after 700 cycles at −35°C and 0.5 C, with an average Coulombic efficiency of 99.86%. Adding 0.05 M ZnSO 4 further stabilizes the electrode/electrolyte interface, enabling 80% retention after 1400 cycles at 4 C. These results demonstrate a practical route to safe aqueous batteries with low‐temperature adaptability and long cycle life. A dilute hybrid electrolyte containing only 10 mol% [EMIM][DEP] simultaneously reorganizes the water hydrogen‐bond network and creates an ionic‐liquid‐rich region at the anode. This coupled bulk and interfacial regulation suppresses freezing and hydrogen evolution, broadens the electrochemical stability window, and enables an aqueous LMO/LTP full cell to retain 90% capacity after 700 cycles at −35°C.

A self-destruct temperature sensor was developed via RAFT-polymerized polyionic liquids in-situ grafted onto CNTs. • The sensor enables active burning destruction of sensitive chip information under external threats. • It exhibits ultra-fast response and recovery (0.2 s) and exceptional long-term stability at 120 °C for 6.5 h. • Temperature-triggered self-destruction was completed within 3.7 s, including 1.4 s of actual combustion. Active transient electronic systems for hardware security need to detect external threats and trigger rapid energy release. However, conventional self-destruction devices use separate sensing and energetic components, complicating device integration. Therefore, we developed a temperature-responsive device based on carbon nanotubes grafted with an energetic poly(ionic liquid) (CNTs-g-PIL). The material was prepared by immobilizing HO-CTA on acyl-chloride-functionalized CNTs, followed by reversible addition–fragmentation chain-transfer (RAFT) polymerization of [VBIM]DCA from the CNT surface. The device showed average response and recovery times of 0.43 ± 0.06 s and 0.42 ± 0.07 s, respectively. Electrical activation at 40–100 V induced rapid combustion, with flame temperatures of 467.13–1375.91 °C. Coupling the device with a logic-control circuit enabled continuous monitoring and automatic activation at 50 °C. In tests with fully packaged commercial memory chips, combustion caused localized thermal damage and functional failure within 3.7 s, with a success rate of 91.7%. This work offers a compact strategy for integrating temperature monitoring and active hardware protection. Download: Download high-res image (228KB) Download: Download full-size image

Waterborne polyurethane (WPU) is widely employed as a carbon fiber (CF) sizing agent; however, the intrinsic polarity mismatch between conventional WPU and epoxy resin (EP) often restricts interfacial adhesion and limits stress transfer efficiency in carbon fiber/epoxy (CF/EP) composites. In this work, a reactive ionic liquid (IL) was incorporated into a bio-based WPU sizing system to modulate interfacial interactions and enhance compatibility with the EP matrix. The introduction of IL provides additional polar interaction sites within the sizing layer while maintaining the dispersion stability of WPU. Remarkable improvements in interfacial and mechanical properties were achieved. At an optimized WPU:IL solid ratio of 1:0.75, the interfacial shear strength (IFSS) increased from 56.15 MPa for unsized composites to 105.91 MPa, corresponding to an enhancement of 88.62%. Meanwhile, the ILSS and flexural strength reached 86.02 and 1810 MPa, representing improvements of 80.22% and 58.77%, respectively. Thermal analysis indicated that the incorporation of IL did not disrupt the fundamental curing chemistry of the EP system but contributed to a more favorable interfacial network integration. The significant improvement in mechanical properties is attributed to the synergistic effect of improved molecular affinity and localized network reinforcement at the fiber–matrix interface, which promotes more efficient stress transfer and suppresses interfacial debonding. This study provides an effective and sustainable strategy for designing high-performance WPU sizing systems for advanced CF/EP composites. Highlights Bio-based ionic liquid (IL) was synthesized to bridge hyperbranched WPU and epoxy. Raw material homology ensures superior molecular compatibility between IL and WPU. IL acts as a reactive bridge to construct an interpenetrating interfacial network. ILSS and flexural strength of CF/EP composites increased by 80.22% and 58.77%. Flexible segments in the interphase alleviate local stress concentration significantly.

In this paper, the ionic-liquid-functionalized onion-like carbon nanoparticles (IL@OLC) were successfully prepared via carbonization of candle soot followed by surface modification with an ionic liquid. Initially, a polyethylenimine (PEI) layer cross-linked by epigallocatechin gallate (EGCG) was assembled in situ on the OLC surface. Subsequently, the as-synthesized ionic liquid (IL-Cl) was grafted onto the PEI@OLC surface through the aza-Michael reaction between the C═C bond of IL-Cl and the amine group of PEI. Finally, an ion-exchange reaction replaced Cl– with PF6–, yielding the ionic-liquid-functionalized OLC (IL-PF6@OLC). The resulting IL-PF6@OLC exhibits exceptional antiwear properties with a low coefficient of friction (COF). The optimal performance was achieved at an additive concentration of 3.0 wt %, where the average COF of base oil decreased from 0.168 to 0.105, accompanied by an 89.3% reduction in wear volume. In addition, the load-carrying capacity increased from 100 to 400 N. The improved lubricating performance is attributed to the ionic liquid grafting, which enhances the adsorption ability of the OLC in the friction interface, thereby maximizing its rolling effect and surface repair capabilities. Moreover, the N, P, and F elements of the IL-PF6@OLC participate in tribochemical reactions under friction heat and mechanical force, forming a more stable and continuous protective film.

Flexible, self-powered, carbon-based perovskite nanowire (PNW) photodetectors (PDs) are promising candidates for next-generation optoelectronics owing to their light weight, mechanical flexibility, low cost, and ability to operate without an external power supply. However, their performance and mechanical robustness are often limited by the buried SnO2/PNW interface, where interfacial defects, unfavorable energy-level alignment, and residual strain impede charge extraction and stress relaxation, thereby increasing non-radiative recombination and accelerating degradation under bending. Herein, we report an ionic-liquid “molecular bridge” strategy using 1-butyl-3-methylimidazolium hydrogen sulfate (BMIMHSO4) to engineer the buried interface in carbon-based self-powered PNW PDs. The BMIMHSO4 interlayer effectively passivates interfacial defects, suppresses non-radiative recombination, optimizes energy-level alignment, and promotes interfacial stress release, thereby simultaneously enhancing device performance and flexibility stability. Rigid devices with a Glass/FTO/SnO2/BMIMHSO4/MAPbI3 PNWs/PMMA/Carbon architecture deliver an outstanding linear dynamic range of 190 dB, a high responsivity of 11.52 A W−1, and a detectivity of 5.45 × 1013 Jones, ranking among the best reported carbon-based self-powered perovskite PDs to date. Notably, the flexible BMIMHSO4-modified carbon-based devices retain 95% of their initial performance after 2000 bending cycles, outperforming most flexible perovskite PDs employing precious-metal electrodes. This work provides a simple, air-processable buried-interface engineering route for low-cost, high-performance, and mechanically reliable flexible PNW photodetectors, accelerating their practical deployment in wearable and flexible optoelectronic applications.

CsPbX 3 perovskite nanocrystals (NCs) have attracted considerable attention for their exceptional optoelectronic properties, yet their poor stability hinders practical applications. In this study, we developed a hydrogen-bonded cocrystal-coated composite (CsPbX 3 @CA-M) by exploiting the rapid co-crystallization of cyanuric acid (CA) and melamine (M) assisted by the ionic liquid Pyr 14 BF 4 (IL). The IL effectively coordinated with unbonded Pb atoms on the perovskite surface, suppressing surface defects and enhancing both quantum efficiency and stability. Simultaneously, the CA-M cocrystal layer further reduced trap states through covalent bonding, improving structural robustness. The CsPbBr 3 @CA-M composite retained its crystallinity and strong photoluminescence under UV irradiation and in 1 m NaOH or 1 m HNO 3 , demonstrating remarkable chemical durability. Even after 30 days of storage, its photoluminescence intensity remained nearly unchanged, whereas that of uncoated CsPbBr 3 NCs decayed rapidly. These findings confirm that CA-M cocrystal encapsulation effectively shields perovskite NCs from environmental degradation, offering a simple and efficient strategy to simultaneously enhance their stability and optoelectronic performance.

Facilitated transport membranes based on poly(vinylamine) (PVAm) exhibit high CO 2 selectivity but suffer from limited stability and performance trade-offs under humid conditions. Herein, we report an ionic liquid (IL) incorporation strategy coupled with covalent organic framework (COF) regulation to spatially tailor transport pathways in PVAm membranes. The incorporation of COF-JLU2 contributes to CO 2 separation through its high adsorption affinity and its role in modulating gas transport pathways, while the IL enhances carrier-mediated CO 2 transport. This structural integration promotes CO 2 sorption and transport while suppressing non-selective gas permeation. As a result, the hybrid membrane achieves a CO 2 /N 2 selectivity exceeding 170 with improved permeance under humid conditions, outperforming conventional PVAm-based systems. The performance enhancement is attributed to the combined effects of COF incorporation and PVAm-IL interactions, although the individual contributions of different transport mechanisms are not quantitatively decoupled in this study. Process simulation further indicates the potential of the developed membranes for post-combustion CO 2 capture based on a preliminary techno-economic assessment. However, further validation with more detailed process models, as well as long-term stability and pilot-scale testing, will be necessary to fully evaluate industrial applicability.

A facile synthesis route of pure FeAl2O4 via self-combustion of ionic liquid is developed using (C2H5)2NH·HCl and urea as cofuels. (C2H5)2NH·HCl not only is the source of cation in ionic liquid but also serves as fuel. The products possess pure hercynite phase, mesoporous structure, and large specific surface areas (89–185 m2 g−1). The visible-light photocatalytic activity of FeAl2O4 is also reported for the first time.

Both TFETFE and 2FB enhance Li⁺-anion interaction, increasing AGGs contents. • 2FB promotes Li⁺-anion interaction more effectively than TFETFE, forming more AGGs. • Inorganic-rich SEI and CEI are generated by deep decomposition of anions in PPB. • Li|PPB|LFP full battery displays a capacity retention of 83.6% after 150 cycles. Due to the low viscosity and weak polarity, fluorinated ethers and fluorinated aromatic compounds are widely used as fluorinated diluents in locally concentrated ionic liquid electrolytes (LCILEs) to improve the electrochemical performance of ionic liquid electrolytes (ILEs). However, the extent to which these two types of diluents regulate Li + solvation structure remains unclear. In this work, two LCILEs were designed using 1,1,2,2-tetrafluoroethyl 2,2,2-trifluoroethyl ether (TFETFE) and 1,2-difluorobenzene (2FB) as diluents, denoted as PPT and PPB, respectively. Raman spectroscopy reveals that both TFETFE and 2FB can strengthen the interaction between Li⁺ and anion, thereby promoting the formation of aggregate ion pairs (AGGs). Compared with TFETFE, 2FB exhibits a more pronounced ability to enhance Li⁺-anion interaction, increasing the proportion of AGGs in PPB electrolyte to 42%, which is significantly higher than that in PPT electrolyte (30%). The enriched AGGs facilitates the preferential reduction and deep decomposition of FSI⁻ at the electrode/electrolyte interphase, leading to the formation of inorganic-rich (LiF, Li 3 N, Li 2 S and Li 2 O) solid electrolyte interphase (SEI) and cathode electrolyte interphase (CEI) with the compact and uniform morphologies. Benefiting from the favorable interfacial chemistry, Li||Cu half battery based on PPB electrolyte delivers a high Li plating/stripping Coulombic efficiency (CE) of 98.7% at 1 mA·cm -2 , exceeding that of PPT (98.0%). In addition, the Li||Li symmetric battery exhibits stable cycling for 160 hours at 2 mA·cm -2 . The Li|PPB|LFP full battery further retains 83.6% of its initial capacity after 150 cycles with an average CE of 99.8%, demonstrating superior electrochemical performance. This work provides practical guidance for the rational selection and structural design of diluents for high performance lithium metal battery electrolytes.

A selective phase for tetracycline antibiotics (TAs) uptake was designed by incorporating [BMIM][PF 6 ]-functionalized ZIF-67-derived carbonaceous material into the diffusive gradients in a thin-films (DGT) device. This material, integrated in the binding gel of DGT (ta-DGT), exhibited specifically strong affinity toward tetracycline (TC), oxytetracycline (OTC), and chlortetracycline (CTC), with adsorption capacities of 12.22, 11.81, and 13.78 µg/disc, respectively. The ta-DGT showed preferential uptake of TAs over coexisting antibiotics and organic contaminants, with adsorption ratios above 80% and stable performance over pH 4–9 and ionic strength of 0.001–0.1 M. Mechanistic analysis indicated that π–π electron donor–acceptor interactions and cation–π bonding facilitated the specific targeting of TAs onto ta-DGT. During 7 days of field deployment in a domestic wastewater treatment plant in Beijing, ta-DGT showed 5–40 times higher detectable concentrations than conventional HLB/XAD DGT devices. These results validated its sensitivity, reliability, and feasibility for the selective separation and quantification of TAs in complex aqueous matrices.

In this study, total flavonoids from Polygonum perfoliatum L. (PPTF) were extracted using ionic liquid-assisted ultrasound and purified by macroporous resin. After optimization, the total flavonoid content increased from 33.9% to 71.2%. HPLC identified hyperoside, kaempferol-3-O-rutinoside, and quercetin. In vitro experiments showed that PPTF exhibited good free radical scavenging activity and inhibitory effects on α-glucosidase and α-amylase. Within the concentration range of 3.13–12.50 μg/mL, PPTF was non-toxic to HepG2 cells and improved glucose uptake, promoted glycogen synthesis, and reduced lipid accumulation in insulin-resistant cells in a dose-dependent manner. In a type 2 diabetic mouse model induced by high-fat diet combined with streptozotocin, intragastric administration of PPTF for four weeks significantly lowered fasting blood glucose in the high-dose group, improved oral glucose tolerance and insulin sensitivity, increased hepatic and muscle glycogen, normalized serum lipid profiles, and alleviated pathological damage in the liver and pancreas. PPTF exhibits favorable hypoglycemic and lipid-regulating effects in both cellular and animal models, demonstrating its potential for development as an adjunctive functional product for glycemic management.

The proliferation of multidrug-resistant pathogens and persistent microbial contamination in industrial settings necessitates the development of robust, processable, and highly efficient antimicrobial additives. Herein, we report HZSM-5/ionic liquid composite, constructed by confining and chemically anchoring a bromine-containing ionic liquid (IL) within the microporous channels of HZSM-5 zeolite. This unique structure imparts exceptional thermal stability, with the confined IL withstanding temperatures exceeding 330 °C and retaining full bactericidal activity after high-temperature (250 °C) processing, demonstrating its suitability for industrial meltprocessing applications. Then, a potent synergistic mechanism wherein the host-guest system catalytically activates molecular oxygen to generate reactive oxygen species (ROS), which in turn oxidizes the bromide anions (Br -) into elemental bromine (Br 2 ) in-situ is proposed. This selfenhancing cycle, confirmed by XPS, EPR, and UV-vis spectroscopy, enables the composite to achieve superior bactericidal efficacy against a range of pathogens, including MRSA, at a significantly reduced IL dosage compared to the pure IL and conventional agents. The mechanism involves a multi-pronged attack combining electrostatic adsorption, dual-action membrane disruption (IL and Br 2 ), and an intracellular ROS burst. This work presents a new design paradigm for creating thermally stable, high-performance antimicrobial materials with significant potential to address pressing industrial challenges in polymer processing, medical devices, and functional coatings.
