The advancement of flexible electronics demands dielectric materials beyond single-mechanism regulation. This study introduces a synergistic dual-regulation strategy combining photo-crosslinking and fluorine effects to concurrently suppress relaxation and conduction losses. We fabricated cross-linked hexafluorobutyl methacrylate (HFMA)/β-cyclodextrin (β-CD)/poly(vinylidene fluoride) (PVDF) ternary composite films via ultraviolet (UV)-induced in situ polymerization. Fluorine incorporation effectively inhibited relaxation loss and leakage current, reducing its density from 6.19 × 10 −6 μC/cm 3 (1 wt% β-CD/PVDF) to 1.79 × 10 −6 μC/cm 3 (30 wt% HFMA composite), thereby mitigating thermal/electrical breakdown risks. Simultaneously, the photo-crosslinked structure restricted chain segment mobility, enhancing breakdown strength from 364.35 MV/m (PVDF) to 545.16 MV/m. The synergistic effect significantly improved energy storage performance, achieving a maximum energy density of 7.21 J/cm 3 at 20 wt% HFMA loading—156% of the value for PVDF. This work provides a new design pathway for high-performance flexible polymer dielectrics featuring low loss, high breakdown strength, and superior energy storage density.

Selective capture of structurally diverse molecules remains a major challenge in chemical separations. Here, we introduce dual-acidic deep eutectic solvents (DESs) in which Lewis acids modulate the Brønsted acidity, creating a synergistic environment for the simultaneous extraction of basic and non-basic nitrogen-containing molecules. Brønsted sites, activated by adjacent Lewis centers, preferentially bind basic heterocycles, while the Lewis sites coordinate with non-basic species, achieving unprecedented extraction efficiencies. Mechanistic studies combining FT-IR spectroscopy, density functional theory, and molecular electrostatic potential analysis reveal that proton transfer, Lewis acid–base coordination, and π–cation interactions collectively govern selective recognition. This dual-acidic design strategy is generalizable across different LA-metal DES compositions and robust against competing chemical species. Our findings demonstrate a rational approach to fine-tune cooperative acid functionalities, establishing a versatile platform for selective molecular capture and separations beyond conventional single-acid systems.

Meta-aramid (PMIA) insulating paper contains micron-scale pore defects that limit its dielectric strength and reliability under high electric field and power conditions. Inspired by a sandwich structure, this study employed self-fabricated polyarylate (PAR) nanofiber membranes as outer layers and commercial aramid paper as the core to fabricate hierarchical PAR/PMIA/PAR nanocomposite insulating paper via a scalable hot-pressing consolidation process. The high-aspect-ratio PAR nanofibers formed a dense interwoven network, reducing pore density and mitigating electrical weak points. During hot pressing, the reversible melting of PAR effectively sealed inter-fiber and interfacial pores, while π–π conjugation and strong hydrogen bonding with PMIA fibers ensured robust interfacial adhesion, suppressing electric field distortion from charge accumulation. As a result, the nanocomposite achieved tensile and breakdown strengths of 97.406 MPa and 114.55 kV/mm, representing increases of 51.3% and 204.3% over commercial aramid paper. After thermal aging at 200°C and 24 h UV exposure, breakdown strengths remained at 62.89 and 71.57 kV/mm (vs. 24.62 and 27.30 kV/mm for commercial aramid paper). Even after 20 crumpling-twisting cycles and 100 folding cycles, breakdown strengths exceeded 46.78 kV/mm, demonstrating outstanding durability and structural stability under extreme thermal, mechanical, and radiation conditions. Compatible with industrial wet-laid papermaking and hot-pressing, this work provides a realistic route toward scalable manufacturing of lightweight insulating papers for high-power motors, transformers, and photovoltaic modules requiring long-term dielectric reliability. Highlight Sandwich-structured nanocomposite with robust π–π conjugation interface. 114.55 kV/mm dielectric strength, 204.3% higher than commercial aramid paper. Tensile strength of 97.4 MPa, 51.3% higher than commercial paper.

In this work, poly(L-lactide-co-ε-caprolactone) (PLCL) copolymers with varying ε-caprolactone (ε-CL) contents that ranged from 0% to 10% were synthesized via ring-opening polymerization of L-lactide and ε-CL at 170°C for 1 h. Fully biodegradable PLCL/poly(D-lactide) (PDLA) blends with stereocomplex (SC) crystallites were fabricated through a solution blending approach. The effects of ε-CL content in PLCL on the crystallization behavior, thermal properties, mechanical performance, and degradation behavior of PLCL/PDLA blends were systematically investigated. The successful synthesis of PLCL was confirmed by 1 H NMR and FTIR analyses. The melting peaks observed in the high-temperature region and the characteristic diffractions in WAXD patterns provided evidence for the formation of SC crystallites in PLCL/PDLA blends. Compared with PLCL, the incorporation of PDLA significantly enhanced the crystallization rate, due to the nucleation function of SC crystallites. With increasing ε-CL content in the copolymer system, the T g and crystallinity of PLCL gradually reduced, and the melting peaks of HC and SC crystals shifted toward lower temperatures due to the reduced sequence regularity. A pronounced improvement in deformability was achieved by the presence of ε-CL segments. As the ε-CL content increased from 1.5% to 10%, the elongation at break rose from 12% to 192%, with the morphology of elongated fibrils. Higher ε-CL contents accelerated enzymatic degradation, with mass loss exceeding 75% after 7 days at 10% ε-CL, because the increased chain mobility may facilitate the penetration of water and Proteinase K into the blend, thereby promoting enzymatic erosion. Overall, high-performance PLA-based composites with excellent biodegradability were achieved via SC crystallization and modulation of ε-CL comonomer content. Summary PLCL copolymers with tunable ε-CL content were prepared and characterized. SC crystallization regulated the crystallization and thermal behavior. ε-CL segments enhance chain mobility and improve blend deformability. Enzymatic degradation kinetics were accelerated as ε-CL content increased.

Bismuth-based alloying materials have emerged as highly promising anodes for sodium-ion batteries (SIBs) due to their high theoretical specific capacity, superior volumetric capacity, and suitable operating voltage; however, substantial volume variation during alloying/dealloying and sluggish reaction kinetics critically compromise their cycling stability. To simultaneously address these challenges, this study designed and engineered a unique bismuth nanoscroll (BNR) structure derived from self-assembled nanosheet scrolling. This architecture substantially enlarges the electrochemically active surface area relative to commercial bismuth powder, thereby facilitating efficient reversible Na + intercalation/deintercalation. Consequently, the BNR anode delivers exceptional sodium storage performance: it achieves a remarkable 99.71% capacity retention after 900 cycles at 1A g −1 and demonstrates ultra-long cycling stability for 2500 cycles even at a high rate of 2 A g −1 . Furthermore, a full cell configured with the BNR anode paired with a Na 3 V 2 (PO 4 ) 3 (NVP) cathode maintains a stable capacity of 243.27 mAh g −1 following 250 cycles at 0.1 A g −1 . Beyond introducing a novel synthesis strategy for high-performance bismuth nanowires that exhibit exceptional cyclability in SIBs, this work provides pivotal insights for developing advanced electrode materials targeting high-energy-density and long-cycle-life sodium-ion batteries. Graphical This article investigates the structure–property relationship of spherically compact bismuth nanoscrolls (BNR) for sodium-ion battery anodes. Bismuth has emerged as a promising anode material due to its high volumetric capacity and stable alloying mechanism. The study reveals that the unique spherical architecture, self-assembled from numerous nanoscrolls, enables high performance and long cycle life in sodium-ion batteries through the synergistic effect of accelerated ion transport via one-dimensional channels and effective strain buffering within the internal space.

Direct transformation of biomass-derived platform compound 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) represents a highly attractive route with significant environmental and economic benefits. The nanozymes with oxidase-like (OXD-like) activity hold great promise for the green oxidation of HMF to FDCA. Herein, an iridium-coated γ-Fe 2 O 3 core-shell nanozyme (γ-Fe 2 O 3 @Ir) was prepared by the reduction of Ir 3+ with glycerol on the surface of γ-Fe 2 O 3, and the structure of the γ-Fe 2 O 3 @Ir nanozyme was confirmed by XRD, HAADF-STEM image, and elemental line-scan analyses results. The magnetic property of the nanozyme not only facilitates its recovery but also effectively enhances its affinity to oxygen. By employing γ-Fe 2 O 3 @Ir nanozyme as the catalyst and atmospheric oxygen as a green oxidant, a near-quantitative conversion (98.5%) of molar level HMF to FDCA was achieved.

Multifunctional membranes have recently attracted considerable attention as promising separation materials for the purification of complex oily wastewater, owing to their capability of simultaneously removing various contaminants. However, the organic polymer substrates utilized in multifunctional membrane fabrication suffer from low biodegradability and poor environmental compatibility, and their preparation processes are often technically complex. In this study, a multifunctional membrane based on cotton fabric (CF) was fabricated through the grafting of polyethyleneimine (PEI) and the deposition of titanium dioxide nanoparticles (TiO 2 NPs) via a surface micro-dissolution technology. The prepared membrane exhibited excellent oil/water separation, as well as remarkable performance in dye removal, heavy metal ion adsorption, and antibacterial activity. Specifically, it achieved a water flux of 1189 L/(m 2 h) for oil/water mixtures while maintaining separation efficiencies above 98%. The modified CF-based membrane also exhibited removal efficiencies of 96.3% for Congo red and 67.8% for chromium ions, respectively. Furthermore, antibacterial assessment revealed that the membrane generated inhibition zones of 8 mm for Escherichia coli and 5 mm for Staphylococcus aureus after a 6 h contact period, indicating satisfactory antibacterial performance. More than 83% of the membrane’s adsorption was recovered after a facile cleaning step, indicating good regeneration performance. Moreover, the membrane demonstrated satisfactory stability under harsh conditions. This work may provide a facile approach for fabricating multifunctional fabric-based membranes for the effective removal of contaminants in complex oily wastewater. Graphical abstract

Developing recycling photo-curing 3D printing materials (especially using renewable biobased feedstocks) can greatly alleviate environmental burden raised by the rapid development of 3D printing industry. Currently, it is still hard to achieve both high performance and excellent recyclability for such materials. In this study, by using a typical biobased phenol (i.e., eugenol) as starting material, we design biobased photopolymers containing dynamic dissociative phenol-carbamate bonds, part of which come from the phenol itself. The obtained materials not only have relatively high biobased contents, but also demonstrate excellent thermal and mechanical properties. Subsequently, the materials are conveniently recycled by a proposed “mixed-monomer assisted recycling” strategy, and high recovery efficiencies in at least three cycles were achieved. Furthermore, the materials indicate exceptional 3D printing performance and functionalities (such as oral bacteria inhibition and shape memory) as well as low environmental impacts. Overall, the combination of rigid biobased feedstocks (especially biobased phenols) and suitable dissociative covalent bonds offers the opportunity to develop high performance, recycling photopolymers with more functionalities and better sustainability.

The efficient treatment of dye-containing wastewater remains a critical environmental issue, primarily due to its biological toxicity to aquatic microorganisms and high chromaticity. In this work, two types of Co₃O₄-functionalized ceramic hollow fiber membranes were designed to activate peroxymonosulfate (PMS) for the efficient removal of dyes from water. Compared to the static-deposited membrane (SCHFM), the dynamic-deposited membrane (DCHFM) demonstrated a higher loading capacity and more uniform distribution of Co 3 O 4 on both the surface and internal pores, leading to a significant enhancement in catalytic performance. Under optimal operating parameters, the DCHFM achieved over 98% removal of rhodamine B (RhB) during the filtration. Radical quenching and electron paramagnetic resonance (EPR) confirmed the involvement of multiple reactive oxygen species, including singlet oxygen ( 1 O 2 ), hydroxyl radical (HO•), sulfate radical (SO 4 •− ) and superoxide radical (•O 2 − ), with 1 O₂ identified as the predominant reactive species. Furthermore, the functionalized membrane exhibited outstanding operational stability and reusability with negligible cobalt leaching. The findings of this study provide a high-performance catalytic membrane system for the advanced purification of industrial wastewater.

The rapid progress of soft robotics and flexible electronics has sparked tremendous demand for elastomers that unite high mechanical strength with intrinsic softness, thereby mimicking the mechanical performance of natural skin. Herein, we report a class of dynamically crosslinked supramolecular polyurethanes that combine skin-comparable low modulus with high strength and room-temperature self-healing, achieved through a segmental molecular engineering strategy. The design leverages entropy-driven soft elasticity together with enthalpy-governed strain-stiffening and energy dissipation, dictated by polymer segment topology. Using a prototypical supramolecular elastomer, we demonstrate that incorporating an isophorone diisocyanate (IPDI) chain extender, whose steric configuration matches that of ureidopyimidinone (UPy), reinforces hydrogen bonding interaction and suppresses premature crystallization. The optimized elastomer exhibits an ultralow initial modulus (<3 MPa) yet undergoes pronounced strain-stiffening, yielding exceptional tensile strength (>50 MPa) and high fracture toughness (∼2×10 5 J m −2 ), outperforming state-of-the-art room-temperature self-healing elastomers. Moreover, the elastomer features hydrophobicity, ensuring stability in underwater applications. These results underscore the promise of segment-level molecular engineering for constructing dynamic polyurethanes with thermoplastic processability, skin-like softness, and unprecedented mechanical robustness.

Non-invasive visualization of glucose metabolism in living organisms remains a major challenge, as existing techniques cannot specifically detect glucose molecules with deep-tissue penetration and without ionizing radiation. To overcome this, we developed an enzyme-activated magnetic resonance imaging strategy (eaMRI) using a biodegradable nanoprobe, CrGOx@Lip, that integrates endogenous Cr 3+ ions with glucose oxidase for glucose-responsive imaging. Our approach leverages GOx not only as a catalytic engine to specifically oxidize glucose but also as a structural template to guide the in-situ synthesis of a potent MRI reporter (paramagnetic chromium gluconate). This design enables direct, specific amplification of MRI signals in proportion to local glucose concentration, achieving an 8.28-fold relaxivity increase. We validated this method for sensitive glucose mapping in vivo, including delineating Warburg-effect-driven tumors and quantifying pathological glucose accumulation in metabolic dysfunction-associated fatty liver disease (ΔSNR% = 18.51 ± 3.72 vs. 1.14 ± 1.39 in controls; p <0.001), and further demonstrated its utility in monitoring therapeutic efficacy via glucose-responsive signal changes. By synergizing enzymatic precision with nanomaterial engineering, our CrGOx@Lip-mediated eaMRI platform provides a glucose-specific, radiation-free, and non-invasive strategy for sensitive metabolic diagnostics in precision medicine.

Sono-photodynamic therapy (SPDT) offers a non-invasive, spatiotemporally precise approach to cancer treatment, but its effectiveness is still limited by poor tumor specificity and penetration. To address this, we developed a cascade-targeted type I/II sensitizer, Ce6-TPP-Phe-Tyr (CTPT), which integrates chlorin e6 (Ce6), triphenylphosphonium (TPP), and a phospho-peptide motif for precise tumor targeting and potent SPDT. Upon dephosphorylation by tumor-overexpressed alkaline phosphatase (ALP), CTPT undergoes enzyme-instructed self-assembly (EISA) into nanoparticles (CTPT NPs), promoting their accumulation and retention in tumors. The TPP cations then guide these nanoparticles to mitochondria, concentrating the therapeutic payload at this critical organelle for cellular energy metabolism. Subsequent ultrasound/laser irradiation further enhances tissue permeability and triggers the generation of both type I and type II reactive oxygen species (ROS), leading to potent oxidative damage. This integrated strategy of EISA and mitochondria-targeted SPDT achieved approximately 86% tumor regression in ALP-overexpressing xenografts. This strategy minimizes systemic toxicity and achieves potent tumor regression by cascade delivery of the therapeutic agent, thereby significantly enhancing the precision and efficacy of SPDT.
