Cellulose films are known for their sustainability, high flexibility, and outstanding mechanical strength; however, they often exhibit limited optical, electrical, and thermal properties. Conventional modification strategies, such as carbonization or physical blending with conductive materials, tend to be energy-intensive and often require specialized equipment or controlled environments. In this study, we report an ultrafast coating of PEDOT:PSS onto a unique cellulose/hydroxyapatite substrate, achieved within just 5 s under ambient conditions without the need for any equipment. The incorporation of hydroxyapatite nanowires between cellulose fibers and PEDOT:PSS enhances the interfacial bonding strength by 2.8 times via multiple interactions, enabling such an ultrafast coating process. The resulting composite films effectively combine the excellent water affinity and mechanical robustness of the cellulose/hydroxyapatite substrate with the superior optical, electrical, and thermal properties of the PEDOT:PSS coating. Based on these advantages, we demonstrate multifunctional devices, including solar-driven water evaporators, wearable strain sensors, and flexible thermoelectric generators, that exhibit competitive performance metrics: a water evaporation rate of 2.02 kg m−2 h−1, salt rejection (20 wt.% NaCl), stable and rapid sensing toward varying human movements, an electrical conductivity of 465 S m−1, and a Seebeck coefficient of 28.21 µV K−1.

Liquid crystal elastomer (LCE) fiber actuators are promising candidates for smart textiles owing to their reversible large-stroke actuation and high aspect ratios. However, current LCEs require ultraviolet (UV) curing and are not recyclable. In addition, research is mainly focused on flat knitted thermo-responsive textiles. Here, a scalable recycling route for smart LCE textiles is developed by melt-extruding a thermoplastic LCE containing a near-infrared photothermal dye. The LCE fibers exhibit ∼30% reversible actuation strain and display light-driven rolling motions with left- or right-turning trajectories according to their programmed twist handedness. Using commercial knitting machines, multi-material plain- and rib-knit textiles are fabricated that exhibit in-plane contraction and out-of-plane deformations including bending and twisting under thermal and photo stimuli. Circularly knitted tubular structures exhibit reversible contraction in both radial and axial directions, reaching approximately 16% in outer diameter, 19% in inner diameter, and 14% in length, enabling applications in autonomous climbing, controlled liquid release, and micro pumping. Finally, thermo-mechanical recycling yields recycled fibers and both flat and circularly knitted textile structures with nearly unchanged actuation performance and comparable mechanical properties, demonstrating robust recyclability. Our results demonstrate the creation of smart textiles that are simultaneously intelligent in function and sustainable in design.

The management of Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is severely hampered by the inability of existing therapies to achieve conformal fitting and sustained drug release within the dynamic, moist vaginal environment. Herein, we report a novel Janus-structured microneedle (MN) system engineered from a poly(vinyl alcohol)/silk fibroin (PVA/SF) hybrid that overcomes these critical limitations through intelligent, hydration-triggered shape adaptation. A facile one-pot process induces spontaneous spatial segregation, forming an asymmetric bilayer architecture with a PVA-rich upper layer and an SF-enriched lower layer. This unique structure enables the device to be pre-programmed into a compact coil for minimally invasive insertion, which subsequently unfurls upon vaginal moisture exposure to achieve conformal contact with irregular wound surfaces. Crucially, we decipher the shape memory mechanism through 2D correlation spectroscopy and molecular dynamics simulations. These analyses reveal a sequential disruption of hydrogen bonds, while hydrophobic interactions from SF β-sheets provide exceptional mechanical stability in the hydrated state. In a rat model of severe vaginal injury, the arbutin-loaded MN (ARMN) scaffold orchestrates a holistic healing process—effectively scavenging ROS, suppressing IL-6-mediated inflammation, promoting VEGF-driven angiogenesis and PCNA-enhanced proliferation, and mitigating surgery-induced dysbiosis. This work establishes a pioneering paradigm of stimuli-responsive, self-adapting medical devices for transformative therapy in complex mucosal tissue regeneration.

The short-wave infrared (SWIR, 1–2.5 µm) spectral window has recently attracted intense attention owing to its intrinsically low scattering, deep penetration, and exceptional robustness under complex environments, capabilities that far surpass those of visible and near-infrared systems. These advantages have positioned SWIR photonics at the core of emerging applications ranging from biomedical imaging and environmental monitoring to autonomous sensing and optical communication. Although state-of-the-art SWIR technologies are predominantly based on inorganic semiconductors such as InGaAs, their high cost, rigidity, and limited compatibility with flexible or biocompatible platforms constrain further deployment. Organic semiconductors have therefore emerged as a compelling alternative, offering molecular tunability, solution processability, mechanical compliance, and scalability for large-area manufacturing. This review provides an overview of recent developments in SWIR materials, emphasizing donor-acceptor small molecules and polymers featuring band gaps below 1.24 eV. Topics addressed include molecular design strategies, structure-property relationships, distinct SWIR absorption and emission characteristics, and their device performance and representative applications in organic photodetectors, solar cells, and light-emitting diodes. Finally, we identify key challenges related to nonradiative losses, stability, charge management, and material–device integration and provide a forward-looking perspective for the development of next-generation SWIR organic optoelectronics.

The rapid advancement of intelligent electronics and radar technologies has created an urgent demand for stimuli-responsive microwave absorbers with dynamically tunable electromagnetic properties. However, most high-performance absorbers remain fixed in their electromagnetic properties after fabrication, limiting adaptability to varying electromagnetic environments. Here, a magnetically reconfigurable Ni@CNT—cellulose liquid crystal film (NCCF) is constructed with a solid-shell/fluid-core architecture based on renewable hydroxypropyl cellulose (HPC). The fluid cholesteric core endows Ni@CNT chains (NCC) with rotational freedom, while the solidified shell preserves mechanical robustness. Under magnetic fields, NCC rotation induces concurrent reorganization of the surrounding HPC matrix through interfacial hydrogen bonding, yielding a multiscale anisotropic framework. The films feature pronounced orientation-dependent microwave absorption (MA), where magnetic-field-induced structural reconfiguration reorganize conductive pathways, dipolar interfaces, and magnetic coupling domains, enabling programmable modulation of Reflection loss (RLmin) and effective absorption bandwidth (EAB). This tunability follows a clear performance trend (NCCF-H > NCCF-R > NCCF-V > NCPF), corresponding to progressively strengthened anisotropic dissipation networks. Consequently, the horizontally aligned NCCF exhibits the strongest attenuation (RLmin = −42 dB at 12 GHz) with X−Ku-band-wide absorption. This work provides a sustainable and scalable strategy for constructing next-generation adaptive electromagnetic absorbers by integrating renewable cellulose liquid crystals with magnetically responsive nanochains.

The development of all-solid-state batteries (ASSBs) with sulfide-based solid electrolytes is a promising strategy for realizing safe Li-ion storage systems with high energy densities. However, the practical implementation of Ni-rich layered cathode active materials (CAMs) with superior theoretical capacities remains hindered by their interfacial instability in sulfide electrolytes and intrinsic structural degradation caused by cation mixing and oxygen losses. To address these challenges, this study introduces a novel flash-light sintering (FLS) technique that can rapidly generate a conformal NiO-like protective surface layer directly from the CAM lattice without using external precursors or extensive thermal treatments. This uniformly engineered nanoscale surface layer undergoes robust chemical and mechanical stabilization by blocking direct contact with the electrolyte, thereby significantly inhibiting parasitic interfacial reactions. Additionally, the NiO-like shell acts as a rigid structural pillar, effectively preventing cation migration, layered-to-rock-salt phase transitions, and the subsequent lattice collapse, thereby preserving the electrochemically active core. Electrochemical assessments demonstrate significantly enhanced performance; at a charge rate of 0.1 C in the normal voltage window, the capacity retention after 100 cycles improves from 55% with 103.8 mAh g−1 and a Coulombic efficiency of 89.13% for the pristine material to 81% with 152.1 mAh g−1 and a Coulombic efficiency of 99.78% for the treated material. In an extended cut-off window, the capacity retention improves from 40% with 90.9 mAh g−1 and a Coulombic efficiency of 86.98% to 78% with 166.3 mAh g−1 and a Coulombic efficiency of 98.9%. Owing to its rapid, scalable, and highly controllable nature, FLS offers a compelling approach for practical surface engineering with a substantial potential for improving both the performance and safety of ASSBs and extending their applicability to various functional oxide materials that require precise and efficient surface modifications.

Non-contact luminescence thermometry featuring high resolution and high sensitivity represents a crucial application of lanthanide upconversion materials. Nevertheless, primarily due to the thermal quenching (TQ) effect, traditional fluorides continue to present significant challenges in attaining real-time, high-sensitivity temperature sensing across a broad temperature spectrum. In this study, two thermometers are developed based on the thermal coupling energy levels (TCLs) and non-thermal coupling energy levels (NTCLs) of CaZrF6:3%Yb; 2%Er. Benefiting from the luminescence thermal enhancement induced by lattice thermal contraction, these ratio-type thermometers demonstrate the ability to operate within an extensive temperature range, spanning from relatively low to high temperatures (193 ∼ 793 K). TCLs and NTCLs display extraordinarily comparatively large relative sensitivity of 1.53 and 1.45% K−1 at room temperature. Most notably, based on NTCLs, the absolute sensitivity value consistently remains above 4.00 × 10−2 K−1 within the high-temperature range (393–793 K), and attains a maximum of 5.08 × 10−2 K−1 at 543 K, which is significantly higher than those of the vast majority of Yb3+/Er3+-doped optical temperature-measurement materials. These results offer a novel approach for the advancement of high-sensitivity and high-resolution sensor devices across a wide temperature range (Especially in high-temperature).

ZnS electroluminescent (EL) fibers currently serve as a crucial component in smart wearable flexible electronic devices. While offering advantages such as excellent flexibility and low power consumption, these fibers still require external high-frequency power to excite luminescence, which limiting their potential in portible and wearable interaction applications. To address this challenge, triboelectric generators (TEG) are employed to effectively harvest electrical energy by converting mechanical energy. The TEG, inspired by origami structures, achieves a maximum output voltage of 228 V, current of 22 µA, and power density of 0.4 W m−2, maintaining excellent performance even after 50 000 compression cycles. The ZnS EL fibers with a coaxial structure of the dielectric and luminescent layers are realized via the microfluidic spinning technology, which has a special advantage in the precise control of the microstructure. Most importantly, a novel energy management circuit is proposed to convert TEG energy into high-frequency alternating current (AC) for driving the EL fibers, which possess a brightness of up to 150.88 cd m−2 under the lower output of TEG. Ultimately, a self-powered, highly luminous ZnS EL fiber with an integrated energy management circuit and TEG has been developed, which makes it possible to provide energy for luminescent fibers through the common mechanical friction.

Ultimately, a self-powered, highly luminous ZnS EL fiber with an integrated energy management circuit and TEG has been developed, which makes it possible to provide energy for luminescent fibers through the common mechanical friction.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"72 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146138922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Plasma catalysis realizes CO2 conversion under ambient conditions through the inelastic collision of high-energy electrons, but the continuous impact of high-energy electrons often leads to the excessive dissociation of formed intermediates. To address this limitation, we designed a biomimetic stoma-shell nanoarchitecture, inspired by natural leaves, to enhance the selectivity of C2+ products. Its microporous shell with vertically aligned pores, emulating natural leaf stomata, functions as a selective barrier that mitigates high-energy electron impact while maintaining reactant transport. Inside, a defect-rich mesoporous network with exposed copper sites promotes C─C coupling and stabilizes C2+ intermediates within confined catalytic spaces. This functional architecture redistributes the active species within the plasma catalytic zone, thereby suppressing undesired side reactions. Catalytic results showed a significant reversal in product selectivity between methanol and ethanol, with a 3-fold enhancement in ethanol selectivity over methanol from 24% to 65%. This work proposes an advanced functional materials design strategy that is broadly applicable to catalytic plasma-driven reactions, integrating electron impact tolerance with catalytic efficiency to direct the desired reaction pathway.
