Consequently, the development of advanced smart wound-dressing systems, such as bioelectronics-integrated wound dressings, has the potential to address numerous clinical challenges associated with effective wound management. Herein, we introduce a versatile Janus film composed of MXene@PEDOT:PSS and bacterial cellulose (designated as MPP/BC), developed as an innovative and adaptable bioelectronics-integrated wound dressing. This material is designed to enhance skin bioelectronics for health monitoring while facilitating accelerated wound healing. The resulting MPP/BC Janus film exhibits remarkable flexibility, high conductivity, photothermal sterilization capabilities, and excellent biocompatibility. These essential characteristics render it suitable for integration into a versatile epidermal sensor capable of real-time monitoring of various human physiological signals. Furthermore, this MPP/BC Janus film-based wound dressing demonstrates significant potential in enhancing therapeutic efficacy to promote wound healing by facilitating epithelial regeneration and increasing collagen deposition. Consequently, this study introduces a promising strategy for developing advanced smart wound-dressing systems aimed at accelerating and optimizing the wound healing process.

Passive daytime radiative cooling (PDRC) is an emerging technology for regulating indoor temperatures without electrical energy consumption by reflecting incoming solar light and emitting thermal infrared radiation into outer space. However, the cooling efficiency of existing PDRC materials remains limited. In this work, we developed a porous composite xerogel integrated with hygroscopic lithium chloride (LiCl) and cellulose nanofibers (CNFs). Benefiting from its highly porous structure and the abundant C-O-C and C O functional groups of CNFs, the xerogel exhibits exceptionally high solar reflectance (97.76%) and mid-infrared emissivity (95.36%) within the atmospheric transparency window (8–13 μm), endowing it with superior radiative cooling properties. Furthermore, the evaporation of water molecules captured by the hygroscopic LiCl under solar irradiation induces additional heat absorption, which effectively suppresses temperature rise and further enhances cooling performance. Consequently, through the combination of radiative and evaporative cooling, the composite xerogel achieves maximum outdoor temperature reductions of 12.65 °C in spring and 27.76 °C in summer, compared to traditional porous polystyrene foam. Energy consumption simulation calculations indicate that the application of the CNF composite xerogel could reduce cooling energy consumption by over 30% in most regions of China. This study demonstrates a highly efficient PDRC material achieved through the synergistic integration of radiative and evaporative cooling strategies, showing strong utilization potentiality on the energy-saving capabilities of dual-functional materials.

Sweat is a key physiological fluid involved in regulating body temperature and maintaining hydration balance. Compared with sensible sweat, insensible sweat is continuously lost in the form of water vapor. Its dynamic variation is closely associated with skin barrier function and basic thermoregulatory activity. However, its low flux and diffuse distribution make reliable detection challenging. In addition, multiparameter analysis of biochemical components in sensible sweat is of significant importance for the evaluation of electrolyte balance and physiological status. In this work, a multiparameter textile platform based on functionalized cellulose materials was developed for monitoring and analyzing the sweating process. Cellulose was employed as the core material platform. By incorporating lithium chloride, humidity-responsive units were fabricated and further configured into a scalable fabric-integrable array, enabling the detection of subtle humidity variations induced by low-flux insensible sweat. As thermal load increased and the system transitioned to the sensible sweating stage, electrochemical sensing fibers were integrated. In combination with the sweat absorption and transport capability of cellulose yarns, the platform enabled the determination of key biochemical parameters in sensible sweat, including pH, sodium, potassium, and uric acid. On-body sweat analysis demonstrated that the textile system enables array-based monitoring of insensible sweat, during the transition to the sensible sweating stage, allowing simultaneous acquisition of multiple physiological parameters. This integrated capability provides a promising approach for continuous monitoring and evaluation of the human sweat rate, electrolyte balance, and related physiological conditions.

Reed-inspired aerogels integrate hydrophobic interfaces and flexible junctions. • MTMS deposition yields high hydrophobicity with a WCA of 139.1°. • PDMS bridges dissipate junction stress under repeated compression. • Dual-siloxane modification limits shrinkage during wet-dry cycling. • Re -dried aerogels retain low thermal conductivity after moisture exposure. Cellulose-based aerogels are promising sustainable thermal insulators, but their hydrophilic skeletons absorb moisture, causing capillary-shrinkage-induced collapse and insulation loss. Meanwhile, rigid hydrogen-bonded or ionically cross-linked networks fatigue under cyclic deformation. Inspired by reed structures, which integrate a water-repellent exterior with a lightweight porous interior, a two-step methyltrimethoxysilane (MTMS)/polydimethylsiloxane (PDMS) dual-siloxane strategy was developed to regulate wettability and junction flexibility in cellulose nanofibril/sodium alginate aerogels, where MTMS forms a water-repellent external interface and PDMS improves the flexibility and cyclic stability of the interconnected porous framework. Chemical vapor deposition of MTMS created a methyl-rich, low-surface-energy layer, and subsequent PDMS vacuum impregnation and thermal curing formed flexible coatings and bridges at fibrillar junctions. The optimized aerogel showed a water contact angle of 139.1° and retained 92.18% and approximately 68% of peak stress after 10 and 100 compression cycles at 50% strain, respectively. Its thermal conductivity changed from 48 mW m −1 K −1 in the dry state to 72 mW m −1 K −1 under near-saturated wet conditions and recovered to 56 mW m −1 K −1 after re-drying following 72 h wet-dry cycling. Although its dry-state thermal conductivity is higher than that of many conventional commercial insulation materials, the aerogel exhibited more stable thermal-insulation performance and partial recovery after re-drying following the 72 h wet-dry cycling protocol. Roof-model tests confirmed more stable insulation under simulated rainfall and weathering. This work provides a structure-oriented strategy for biomass-derived aerogels in wet-dry environments.

The scalable production of chemically tailored cellulose nanofibrils (CNFs) remains challenging because native cellulose lacks sufficient chemical versatility for simultaneous fibrillation and functional regulation. Here, we develop a highly efficient swelling-modification strategy using a hydrated deep eutectic solvent (Zn(OAc) 2 /ChCl/H 2 O) to enable efficient CNF production and programmable chemical modification. Zn(OAc) 2 regulates proton activity through buffering effects, suppressing excessive hydrolysis and preserving the crystalline structure of CNFs with an ultrathin diameter (3–4 nm), high aspect ratio (~1800), high degree of polymerization (600–900), and high yield (93%). By incorporating diverse cyclic anhydrides, this DES system is transformed into a multifunctional operating platform, enabling customizable CNFs with diverse chemical functionalities, including carboxyl groups, double bonds, bridged bicyclic structures, and aromatic rings. This highly efficient swelling-modification strategy provides a scalable and expandable route toward customized CNFs, advancing the design of cellulose-based functional nanomaterials.

Using waste cotton stalk fibers to prepare highly hydrophobic eMCC for PLA composites. • As a nucleating agent, eMCC enhances PLA crystallinity and crystallization rate. • Hydrogen bonding and van der Waals forces give composite ductility and barrier. • It presents a novel strategy for sustainable applications of PLA-based eco-friendly materials. Poly(lactic acid) (PLA) is a promising biodegradable polymer, yet its inherent brittleness, poor barrier properties, and slow crystallization rate limit its application in food packaging. In this study, hydrophobically modified microcrystalline cellulose (eMCC) and poly(butylene succinate- co -terephthalate) (PBST) were incorporated into PLA via solution casting to prepare a ternary composite with balanced properties. Characterization by polarized optical microscopy, X-ray diffraction, and differential scanning calorimetry demonstrated that eMCC promoted heterogeneous nucleation of PLA under isothermal conditions, while PBST served as a ductile toughening phase. Owing to synergistic interfacial interactions, primarily hydrogen bonding and van der Waals forces, eMCC was uniformly dispersed and exhibited strong interfacial adhesion with both polymer phases. The resulting composite achieved a tensile strength of 39.7 MPa while retaining a high elongation at break of 199.9%, reflecting a favorable balance between stiffness and toughness. Barrier property measurements revealed that the water vapor and oxygen barrier properties were improved by 18.0% and 26.1%, respectively, compared with neat PLA. This work provides an effective strategy for utilizing hydrophobically modified microcrystalline cellulose to develop food packaging materials with high performance and potential biodegradability.

The development of sustainable separation membranes based on natural minerals and renewable biomass has emerged as an attractive strategy for environmentally friendly wastewater treatment. Here, a sustainable kaolin/cellulose nanofiber (K/C) composite membranes were fabricated via a vacuum filtration self-assembly successfully, employing exfoliated kaolin as the structural framework and cellulose nanofiber (CNF) as a hydrophilic reinforcing agent. The optimized composite membrane (K/C-3) exhibited superior underwater superoleophobicity with an underwater oil contact angle of 172.7°. Specifically, K/C-3 delivered remarkable separation performance toward diverse surfactant-stabilized oil-in-water emulsions, achieving a high permeance of 1353-3491 L m −2 h −1 bar −1 and a separation efficiency exceeding 99%. Furthermore, the membrane maintained stable separation efficiency above 98.6% and favorable permeance under harsh service conditions, encompassing a broad pH range of 1-13, high salinity of 1-5 wt%. Density functional theory (DFT) calculations were performed to elucidate the intrinsic interfacial mechanism governing the evolution of surface wettability in composite membranes. Moreover, K/C-3 achieves a flux recovery rate of 99.7% after single short-duration filtration followed by water rinsing, exhibiting favorable antifouling performance. This work highlights the potential of integrating naturally abundant minerals with renewable biomass for the development of sustainable separation membranes for oily wastewater treatment.

Transition metals such as Fe 3+ and Cu 2+ are essential for fundamental biological processes, yet their excess can trigger diverse symptoms and diseases. Therefore, precise detection of Fe 3+ /Cu 2+ via real-time and visual analytical techniques is urgently required. In this work, cellulose-based fluorescent material was designed via Steglich esterification by grafting perylene-3,4,9,10-tetracarboxylic acid (PTCA) onto cellulose acetate (CA) backbone. The resulting materials (CA-PTCA) exhibited bright yellow fluorescence, which was quenched in the presence of Fe 3+ /Cu 2+ , providing a highly sensitive detection platform. The fluorescence quenching by Fe 3+ occurs via a photoinduced electron transfer (PET) mechanism with CA-PTCA, while that by Cu 2+ proceeds through coordination. Moreover, the excellent processability of the CA backbone enables CA-PTCA to be fabricated into diverse material forms, including inks, coatings, films, aerogels, and fibers, all of which retain outstanding fluorescence properties. This work highlights the potential of cellulose-based fluorescent materials for multifunctional applications in sensing and information encryption.

Construct a dual-network structure to achieve a leap in substrate performance • Fluorinated cellulose adaptively tunes the liquid-metal (LM) interface, enabling ultra-durable printed electronic devices. • Excellent sensing performance and diverse applications Liquid metals (LMs) are promising for printed electronics, but their durability is limited by weak substrates and LM oxidation/leakage. Here, we propose a dual strategy combining aqueous polyurethane (WPU) substrate regulation and LM interface optimization. By introducing dimethylglyoxime (DMG) and Zn 2+ , a dual-network structure with multiple hydrogen bonds and metal-ligand coordination bonds is formed, enabling the WPU-Zn substrate to achieve a tensile strength of 21.6 MPa, an elongation at break of 1000%, and a self-healing efficiency of 98.3% after 24 h at room temperature. Fluorinated bacterial cellulose (FBC) is further prepared to mediate the WPU-Zn/LM interaction via adaptive dipole-dipole forces, endowing the system with excellent tensile stability and environmental durability. Using DIW 3D printing, flexible printed electronic devices are fabricated; the serpentine sensor shows a stable linear response (GF = 0.3, R 2 = 0.98), fast response/recovery times (196.8/246.8 ms), and durability over 2000 cycles, achieving 98.6% gesture-recognition accuracy in human-machine interaction. A customized electrode patch retains 95% of ECG signal amplitude after 12 h of monitoring, clearly outperforming commercial gel electrodes. This work provides a comprehensive solution for durable LM printed electronics, facilitating large-scale manufacturing and commercialization for wearable and biomedical applications.

This study reports the development of a beeswax-based Pickering emulsion stabilized by TEMPO-oxidized cellulose nanofibers (TCNF) and titanium dioxide nanoparticles (TiO 2 ) as co-stabilizers, aimed at fabricating multifunctional coatings with enhanced hydrophobicity and UV-shielding performance. By systematically varying the TCNF: TiO 2 mass ratio (1:0 to 1:4), the structural characteristics of the composite stabilizers, emulsion stability, rheological behavior, and coating functionality were comprehensively evaluated. The results revealed a synergistic stabilization mechanism: TCNF imparted steric hindrance and electrostatic repulsion to suppress droplet coalescence, while TiO 2 reinforced interfacial mechanical integrity and contributed intrinsic UV-blocking capacity. At a TCNF: TiO 2 ratio of 1:3, the emulsion exhibited optimal comprehensive properties, including high emulsification efficiency, long-term storage stability (30 days), strong interfacial film formation, and a water contact angle exceeding 120° after coating application. Furthermore, the incorporation of TiO 2 significantly improved the UV shielding performance of the coating in both UVA and UVB regions, whereas TCNF reinforced the tensile strength of the paper substrate via hydrogen bonding and three-dimensional network formation. Overall, this work establishes a sustainable strategy for the functionalization of cellulose-based materials and highlights the potential of bio-inorganic composite Pickering emulsions in eco-friendly packaging, specialty papers, and green protective coatings.

To address the problems of poor mechanical properties and strong hygroscopicity of the existing eutectogels, this study presents a novel eutectogel containing carboxymethyl cellulose (CMC) designed for wearable strain-sensing applications. The gel was synthesized via a rapid photopolymerization strategy using a choline chloride-urea deep eutectic solvent to dissolve CMC, combined with hydroxyethyl acrylamide as the monomer and phytic acid as a multifunctional crosslinker. The optimized eutectogel exhibited exceptional high stretchability (1189% strain), tensile strength (1166 kPa), and toughness (6.1 MJ/m 3 ), alongside remarkable optical transparency (91% transmittance). The incorporation of phytic acid enhanced hydrogen-bonded crosslinking, enabling self-healing within 3.2 s. The dual ionic/protonic conductive network endowed the gel with high strain sensitivity (gauge factor: 8.81 at 150–300% strain) and temperature resilience, maintaining stability across a wide temperature range (−20 to 60 °C). Unlike conventional hydrogels, this eutectogel demonstrated superior environmental stability, with minimal weight fluctuation (±4%) after 7 days under ambient conditions. This eutectogel-based flexible sensor can monitor both large joint movements (e.g., knee bending) and subtle muscle activities (e.g., facial expressions). This work provides a construction strategy of eutectogel by integrating green chemistry, multifunctional performance, and scalable fabrication, offering a promising platform for durable, high-sensitivity wearable electronics.

Astaxanthin (AST), a natural lipid-soluble carotenoid, exhibits numerous advantageous biological activities. However, its widespread utilization is limited by strong hydrophobicity and poor stability. To overcome these limitations, the AST-loaded zein/sodium carboxymethyl cellulose composite nanoparticles (AZC NPs) were prepared primarily via electrostatic interactions and hydrogen bonding. AZC NPs showed a spherical shape with a mean size of approximately 250 nm. As expected, due to its high negative zeta potential (−33.10 ± 2.72 mV) and the decoration of sodium carboxymethyl cellulose, AZC NPs demonstrated excellent stability against different environmental stresses. Notably, AZC NPs possessed sustained-release behavior and better antioxidant activity compared to those of free AST. These findings suggested that AZC NPs had significant application potential in the food industry.
