Thiol-ene click and DLP printing enable tunable 3D porous flexible scaffolds. • In-situ PANI network provides temperature-adaptive pressure sensing response. • Stable performance from 30 to 90 °C and over 10,000 loading-unloading cycles. • Sensor arrays achieve foot-pressure mapping and real-time motion recognition. With the rapid development of flexible wearable electronics for health monitoring, motion recognition, and human-machine interaction, pressure sensors capable of delivering stable outputs under complex environmental conditions are increasingly needed. However, most existing devices suffer from fatigue-induced fracture of conductive networks, irreversible mechanical deformation, and temperature-dependent signal drift, which significantly undermines their reliability. Here, we report a temperature-adaptive flexible pressure sensor fabricated by integrating thiol-ene click chemistry with digital light processing (DLP) 3D printing. A three-dimensional porous elastic scaffold was constructed from a PETMP/PUA/IBOA matrix using NaCl as a sacrificial porogen, followed by the in-situ formation of a dynamically reconfigurable polyaniline (PANI) conductive network. The sensor exhibits stable and predictable pressure responses across 30–90 °C, enabled by temperature-enhanced polymer chain mobility that increases compressive deformation and amplifies resistance variation under the same load—from −3.5% to −29%—thus enabling intrinsic signal self-compensation without additional circuitry. The device maintains highly consistent performance after over 10,000 compression cycles, demonstrating excellent mechanical resilience and electrical durability. Moreover, when configured as an array, it enables real-time visualization of plantar pressure distribution, accurate motion pattern recognition, and detection of thermal tactile differences under identical pressure. This work presents a material-level strategy for achieving coupled temperature-mechanical-electrical self-adaptation and provides a promising platform for high-reliability flexible pressure sensors designed for complex or variable environments.

Six new phenylazophenol derivatives with tunable substituents were designed to address highly selective Li + /Na + separation. • Structure-performance analysis identifies typical phenol HS-5 as optimal extractants and establishes clear design rules. • The new HS-5/TOPO synergistic system achieves 95.3% single-stage extraction and 99.6% Li + recovery in two stages. • The mechanism underlying the high Li + /Na + selectivity and stability was elucidated by combined DFT and experimental analyses. As brines creasingly constitute source of lithium, the selective extraction of Li + from Na + -rich, high-salinity matrices has become a critical challenge in materials design. In this study, six phenylazophenol derivatives with systematically tunable were designed and synthesized to explore Li + /Na + separation from lithium-containing mother liquor, with structures by 1 H NMR and mass spectrometry. Systematic evaluation of electronic and steric substituent effects established clear structure–performance relationships, identifying 2-phenylazo- 4-trifluoromethylphenol (HS-4) and 4-methanesulfonyl-2-phenylazophenol (HS-5) as the most efficient extractants. A hetero-coordination synergistic extraction system based on HS-5 and trioctylphosphine oxide (TOPO) was further developed and optimized. The optimized system achieved a single-stage Li + extraction efficiency of 95.3%, a Li + /Na + separation factor of 293, and a stripping efficiency of 95.4%. Two-stage cross-flow extraction enabled 99.6% Li + recovery with only 9.3% Na + co-extraction, demonstrating that near-complete lithium removal can be realized with minimal stages. The HS-5/TOPO system retained 79.9% extraction efficiency over ten extraction-stripping cycles without significant degradation. Mechanistic investigations revealed a 1:2 Li + –ligand stoichiometry by Job's method, while DFT calculations showed that HS-5 coordinates to Li + in a bidentate manner through phenolate-O and azo-N, with two P O donors from TOPO completing the distorted tetrahedral coordination environment. These findings underscore the considerable potential of phenylazophenol-based systems for efficient lithium recovery from brines.

Cellulose-based hydrogels hold great promise as electrolytes for aqueous Zinc-ion batteries (ZIBs), yet their performance is hindered by chain aggregation, overly strong Zn 2+ -cellulose coordination that slows ion transport, and parasitic reactions triggered by free water and sulfate species. Here, we design a multifunctional cellulose nanofiber (CNF) hydrogel electrolyte incorporating copper hybrid cluster Cu 4 I 4 (L) 4 (L = 3-Fluoropyridine (3-FPy)) to address these intrinsic limitations. Strong interactions between the clusters and cellulose chains prevent molecular aggregation and introduce additional crosslinking, reorganizing the network into a more continuous and uniform 3D architecture. Unexpectedly, the hydrogel develops a sandwiched structure consisting of dense outer layers that homogenize Zn 2+ flux and shield the anode from free water, and a porous intermediate layer that serves as an electrolyte reservoir to facilitate long-range ion migration. The clusters exhibit weaker affinity toward Zn 2+ than cellulose, mitigating excessive Zn 2+ -polymer coordination and enabling faster ion movement. Their spatially polarized charge distribution also provides sequential Zn 2+ hopping sites, further promoting directional ion transport. Meanwhile, strong binding with H 2 O and SO 4 2− converts free water into bound water and immobilizes anions, thereby suppressing H 2 O- and SO 4 2− -driven parasitic reactions. Benefiting from this cooperative regulation of microstructure, ion coordination, and water chemistry, the CNF@Cu 4 I 4 (L) 4 hydrogel exhibits high ionic conductivity, stable Zn plating/stripping, and effectively suppressed side reactions. As a result, Zn anodes achieve a long-term cycling stability up to 1200 h, and capacity retention of 99.5% over 2000 cycles for Zn||Polyaniline full cells. This work establishes a robust strategy for engineering cluster-modified hydrogels toward safe, durable, and high-performance aqueous ZIBs.

Regulating structural and electronic coupling in layered vanadium oxide is crucial for achieving high stability and fast reaction kinetics in aqueous zinc-ion batteries (ZIBs). Herein, we engineer a layered vanadium oxide cathode (LaPVO) through the intercalation of La3+ and in situ polymerized polyaniline (PANI) into the vanadium oxide framework. The La3+ functions as rigid structural pillars that expand and stabilize the interlayer spacing, while the conjugated PANI chains establish continuous electronic pathways and buffer mechanical strain. Through this interlayer regulation, the structural and electronic coupling within the vanadium oxide host is effectively reinforced, thereby accelerating Zn2+ diffusion, enhancing charge transport, and suppressing phase degradation during prolonged cycling. Comprehensive structural and spectroscopic characterizations verify the successful cointercalation of La3+ and PANI, accompanied by an increased V4+ content and pronounced interfacial charge redistribution. Owing to the synergistic structural-electronic regulation, the LaPVO cathode delivers a high reversible capacity of 358 mAh g–1 at 0.3 A g–1 and exhibits remarkable cycling stability, retaining 331 mAh g–1 after 200 cycles and 209 mAh g–1 after 1000 cycles. In addition, LaPVO demonstrates outstanding rate capability with minimal capacity decay under high current densities. Density functional theory calculations reveal strengthened Zn2+ adsorption, an increased density of electronic states near the Fermi level, and reduced Zn2+ migration energy barriers, providing fundamental insight into the experimentally observed performance enhancement. This work establishes a general and effective interlayer engineering strategy for designing robust vanadium-based cathodes, offering new opportunities for grid-relevant aqueous ZIBs.

Membrane fouling is a key issue restricting the development of membrane distillation (MD), especially when the types of contaminant are becoming diverse. In this study, a Janus membrane modified with wettable conductive hydrogel is prepared, which is synthesized via an interfacial free radical polymerization (FRP) of poly (ethylene glycol) diacrylate (PEGDA) monomers, utilizing the Joule heating effect of carbon nanotubes (CNTs). The resulted hydrogel exhibits a unique sandwich structure of dense hydrogel film-loose CNTs networks-dense hydrogel film. Firstly, positive roles of the ultra-thin PEGDA hydrogel and hydroxylated porous CNTs layer in increasing intermediate water ration and reducing water evaporation enthalpy are revealed. Then, their rejecting properties against contaminants with different charges are accessed, including cationic/anionic surfactants, cationic/anionic dyes and semi-volatile organic compound aniline. In the electric field-assisted MD system, switching the connected electrodes allows the membrane to resist these variously charged pollutants based on the enhanced electrostatic repulsion. Without an electric field, the transport of aniline molecules can be restricted based on size sieving effect and intermolecular hydrogen bond. These findings provide a strategy for constructing all-round anti-fouling MD system and reveal its application prospects in the recycling process of high-salinity organic wastewater.

Polymer composites with room temperature magnetoresistance (MR) are attractive for emerging magnetic sensors and information-storage devices in the era of the Internet of Things. In this work, the magnetorsistive polyaniline (PANI) functionalized magnetic Ti 3 C 2 T x Composites were prepared by solvothermal and in-situ polymerization method. By decorating non-magnetic Ti 3 C 2 T x with magnetic Fe 3 O 4 particles and tuning the Fe 3 O 4 loading on Ti 3 C 2 T x , the room temperature magnetoresistance can be effectively controlled. The Ti 3 C 2 T x /PANI (T/P) composites exhibit positive MR of 4.65% at 2 T, while the Fe 3 O 4 –Ti 3 C 2 T x /PANI (FT/P) composites demonstrates negative MR of -11.13% at 2 T with 60 wt% Fe 3 O 4 loading in Fe 3 O 4 –Ti 3 C 2 T x . Structural and morphological characterizations (SEM, TEM, XRD, FT-IR and XPS) confirm the successful fabrication of FT/P composites. The positive MR in T/P is well described by the wave-function shrinkage model, and the negative MR in FT/P composites is quantitatively fitted by the forward interference model. The localization length ( a 0 ), hopping distance (R hop ) and density of states at the Fermi level (N(E F )) are evaluated. The localization length decreases with increasing magnetic field for all samples and is significantly larger in T/P than in FT/P composites. This work demonstrates a simple and effective strategy to achieve tunable negative MR at room temperature PANI composites for magnetic sensing and data-storage applications.

Agricultural films have attracted considerable attention in recent years. Herein, four types of organic-inorganic complex red light conversion agents ( W-2L , W-8L , S-8L , H-8L ) were designed, the S-8L conversion agent exhibits an extremely broad ultraviolet absorption range of 200-400 nm. Contact angle (142.7°) tests confirmed its excellent hydrophobic properties, enabling better compatibility with LLDPE substrates. Meanwhile, its outstanding photothermal stability of S-8L was demonstrated by a long red fluorescence lifetime: 478.14 μs, an exceptional fluorescence quantum yield: 76.77 %, a high initial decomposition temperature and an extended ultraviolet aging resistance period. Furthermore, the S-8L1 conversion film was utilized to assist in the cultivation of Chlorella cells, demonstrating its excellent UV-blocking and red-light conversion capabilities, significantly increasing both biomass and chlorophyll content. This work proposed a potential way to develop highly efficient light conversion agents by regulating the inorganic-organic functional groups.

Flexible supercapacitors have emerged as promising energy storage devices, owing to their high power density and long cycle life. However, the development of electrode materials with high specific capacitance, superior electrochemical and mechanical stability remains a critical challenge. In this work, we report a facile strategy for fabricating cellulose nanofiber (CNF)-carbon nanotube (CNT)@polyaniline (PANI) nanocomposite aerogels via TEMPO oxidation, freeze-drying, and in-situ polymerization. The CNFs serve as a dispersive scaffold to uniformly distribute CNTs, forming a three-dimensional (3D) interconnected network, while PANI coats the CNF-CNT hybrid to construct a core-shell structure, enhancing pseudocapacitive performance. The resulting CNF-CNT@PANI aerogel exhibits a hierarchical porous structure with a high specific surface area of 121.4 m 2 g -1 and low density of 12.8 mg cm -3 . The assembled flexible supercapacitors deliver a high areal specific capacitance of 722.4 mF cm -2 at 2 mA cm -2 , long-term capacitive cyclic stability (86% capacitance retention after 3000 cycles), and remarkable mechanical stability (95.2% capacitance retention after 200 bending cycles). Additionally, the device achieves a maximum areal energy density of 99.5 μWh cm -2 at a power density of 1005.4 μW cm -2 , outperforming many reported PANI-based supercapacitors. This work provides a feasible approach for designing high-performance flexible electrode materials for next-generation energy storage systems.

The wide occurrence of sulfonamide antibiotics in water environments poses a great threat to ecological system and human health. Cobalt-based catalysts are well known for advanced oxidation processes (AOP), but the synergistic role of heteroatoms is still uncertain. In this work, a new type of heterogeneous Co based catalyst with sulfur as the ligand (Co@S-N-C) was transferred through a straightforward one-pot pyrolysis approach for efficient activating peracetic acid (PAA) to degrade sulfadiazine (SDZ). Systematic characterization confirmed that the co-doping by S and N in carbon induced the formation of several cobalt species (Co 0 , Co 2+ , and Co 3+ ) and built a unique electronic structure featuring in abundant defects and large specific surface area. The Co@S-N-C/PAA system exhibited exceptional catalytic efficacy, accomplishing total SDZ degradation in 25 min and a substantial mineralization rate of 78.2% within 90 min, markedly surpassing the performance of single heteroatom-doped catalysts (Co@N-C and Co@S-C). Mechanistic investigations indicated that •OH and CH 3 COO• contributed 66.4% and 34.1% to SDZ degradation, respectively. DFT calculations revealed that S-N co-doping increased the electron transfer from low-valent cobalt sites to PAA, promoting O-O bond splitting. The catalyst exhibited excellent stability with 71% activity retention and minimal Co leaching (5%) after four cycles. Based on these results, five primary degradation pathways for SDZ were proposed, and the results of ecotoxicity analysis showed that the transformation products were less toxic. Overall, this work provides significant insights into the development of high-performance dual-heteroatom-doped catalysts to form the PAA-mediated AOP for wastewater treatment.

Aromatic amines, particularly aniline derivatives, serve as pivotal intermediates in the manufacture of dyes, pharmaceuticals, and polymers. However, their conventional synthesis remains heavily reliant on fossil feedstocks and frequently employs toxic reagents. The valorization of lignin presents a promising, renewable pathway to these valuable compounds, yet the reactivity of lignin-derived phenols varies markedly depending on their functional group substituents. Herein, a pronounced "promotion-inhibition dichotomy" is reported. Alkyl substituents substantially enhance reactivity-achieving a 44.3 mol% yield of aromatic amines from 4-propylphenol, representing a 34.7% increase over phenol. Conversely, methoxy groups exert a strong inhibitory effect in limiting the yield of aromatic amines from 4-propylguaiacol to only 11.0 mol%. Furthermore, Mo-Ga/HZSM-5 catalyst employed under NH 3 -H 2 atmosphere effectively doubled the yield of aromatic amines to 25.9 mol%. A sequential hydrodeoxygenation-amination strategy is further devised, boosting the yield to 34.1 mol%. Notably, by integrating this two-step strategy with a lignin-first biorefining approach, a 16.6 mol% of aromatic amines (based on lignin) could be achieved from birch. This study elucidates key reactivity principles in lignin valorization and demonstrates an integrated strategy that advances the sustainable production of aromatic amines from renewable biomass.

Hydrogel-based zinc–ion batteries (ZIBs) stand out as promising flexible energy storage devices, benefiting from their synergistic advantages of high theoretical specific capacity, reliable safety performance, and cost-effectiveness. However, conventional hydrogel-based ZIBs are plagued by inadequate ionic conductivity and structural instability at subzero temperatures, which consequently lead to sluggish Zn-ion migration kinetics and severe capacity decay. Herein, we introduced zwitterionic proline (PL) as an antifreezing additive into cross-linked polyacrylamide/carboxymethyl chitosan (PAM/CMCS) to address the above-mentioned challenges. PL can reduce hydrogen bonds between free water, thus endowing the hydrogel electrolyte (HE) with good antifreezing and antidrying performance, interfacial adhesive, high ionic conductivity (30.20 ± 0.47 mS/cm), and enhanced interfacial adhesion. Notably, the PL additive facilitates more uniform zinc deposition in the PAM/CMCS/PL electrolyte relative to the bare PAM/CMCS electrolyte and the ZnSO4 aqueous electrolyte. Accordingly, the PAM/CMCS/PL HE confers outstanding long-term cycling stability on the Zn//Zn symmetric cell. The asymmetrical Zn//MXene@PANI flexible ZIBs can deliver a specific capacity of 154.8 mAh/g at 0.5 A/g and maintain 84.9% capacity with an excellent Coulombic efficiency above 99% after 500 cycles. This flexible ZIB can withstand severe deformations and operate normally at low temperatures (75.2 mAh/g at 1.0 A/g, even at −30 °C). High-performance flexible ZIBs with outstanding low-temperature tolerance are successfully fabricated in this work, providing insightful references for advancing multifunctional flexible energy storage systems and wearable electronics.

Organic coatings tend to lose their
corrosion protection
during
service in a marine environment. In this study, a dual-layer composite
polyurethane (c-PU) coating consisting of a superhydrophobic bottom
layer and a self-healing polyurethane surface layer was designed for
durable corrosion protection. The bottom layer was constructed by
bonding praseodymium-loaded polyaniline-modified hexagonal boron nitride
(Pr 3+ @PANI@h-BN) nanoparticles with epoxy resin. The surface
layer was prepared by the synthesized self-healing polyurethane with
dynamically reversible Diels–Alder covalent bonds. Tafel polarization
curve tests demonstrated that the c-PU coating exhibited significantly
improved corrosion resistance, with a corrosion current density as
low as 95.17 pA/cm 2 . The electrochemical impedance spectroscopy
revealed that the low-frequency impedance modulus of the pristine
c-PU coating was 8.9 × 10 8 Ω·cm 2 , which decreased to 9.9 × 10 4 Ω·cm 2 after scratching. Upon thermal heating at 130 ° C for
10 min, the value returned to 8.7 × 10 8 Ω·cm 2 , indicating complete restoration of its barrier properties
against corrosion media. In summary, the bottom layer provides corrosion
inhibition through active corrosion inhibition, passivation, and a
physical barrier, while the surface layer maintains integrity via
its self-healing ability. The synergy of the two layers enables the
coating to deliver long-term protective performance in harsh corrosive
environments, offering a promising strategy for extending the service
life of marine steel structures.
