While adhesive patches are vital for emergency and surgical trauma care, especially in sealing tissue defects, conventional variants exhibit inadequate bonding in moist conditions, which severely restricts their use for tissue sealing under mechanical pressure and in bioelectronic applications. Herein, we developed a resilient, rapidly adhesive bioelectronic patch (CAA) engineered via photoinitiated copolymerization of carboxymethyl cellulose methacrylate (CMC-MA), acrylic acid, and N -hydroxysuccinimide acrylate. Crucially, CMC-MA acts dually as cross-linker and matrix-forming monomer, enabling exceptional mechanical tunability with tensile stress reaching 5 MPa alongside outstanding cytocompatibility. The CAA patch can rapidly adhere to wet tissues, achieve mechanical sealing of defects by withstanding burst pressures exceeding 600 mmHg, and maintain consistency in real-time monitoring at the dynamic biointerface. In vitro porcine tissue models—including lung leakage, gastric perforation, and cardiac injury—and murine adhesion assays confirm superior wet adhesion and long-term interfacial stability. As a versatile bioelectronic interface adhesive, CAA ensures stable device-tissue integration for wearable sensors, enabling high-fidelity dynamic monitoring of ECG and EMG signals. This tough, ultrahigh-burst-pressure adhesive patch presents a promising application platform for wearable electronics, electronic skin, biosensing, and related biomedical systems.

A novel ethyl cellulose-sodium alginate/chitosan/curcumin (EC-SA/CS/Cur) composite microgel system was developed through a one-step emulsion method. Optimized homogenization at 1,300 rpm for 2 min enabled consistent fabrication of EC-SA/CS/Cur microgels with a mean particle size of 2.85 μm. The microstructural morphology, particle size distribution, and chemical composition of the optimized EC-SA/CS/Cur microgels were characterized by microscopy, laser particle size analysis, and Fourier-transform infrared spectroscopy. The microgels exhibited a curcumin encapsulation efficiency of 54.4 ± 6.8% and a drug loading capacity of 0.032 ± 0.004%. The microgels exhibited excellent stability under enzymatic and physiological pH environments while displaying a unique sustained-release profile in ethanol-containing media; under agitated conditions, a cumulative release of 3.2 μg/mL was achieved within 6 h, representing a 28.0% increase in cumulative release compared to static conditions. The minimum inhibitory concentration of EC-SA/CS/Cur microgels was determined as 675 μg/mL; after 3 h of exposure, their antimicrobial efficacy significantly outperformed free curcumin. These results confirm that the EC-SA/CS microgel system acts as an effective delivery vehicle, markedly enhancing curcumin’s antimicrobial performance. This study provides a promising strategy for developing stable, high-efficiency curcumin delivery systems with improved therapeutic potential, particularly for oral/throat protection against alcohol-induced irritation via on-site curcumin release to alleviate local inflammatory damage.

The growing demand for sustainable polymeric materials has driven efforts to replace petroleum-based polyols in rigid polyurethane foams (RPFs) with renewable alternatives. Lignin, owing to its abundant hydroxyl groups and aromatic structure, is considered a promising candidate; however, its intrinsic rigidity and structural heterogeneity often limit its incorporation and compromise foam performance. In this study, industrial Kraft lignin (KL) was liquefied using 1,4-butanediol and employed as a bio-based polyol for RPF fabrication. Process optimization demonstrated that catalyst, surfactant, and water contents played critical roles in regulating foam density and compressive strength. To enhance mechanical performance, microcrystalline cellulose (MCC) derived from tobacco stems was introduced as a reinforcing phase. At an MCC loading of 5 wt%, the compressive strength at 10% strain increased by 34%, from 171.6 ± 7.5 to 229.7 ± 12.6 kPa, with enhancement up to 50% strain, while the apparent density increased slightly from 85.4 ± 2.0 to 93.5 ± 2.6 kg·m −3 . MCC incorporation also reduced the water contact angle from 110.3° to 100.0°. Morphological analysis revealed that increased system viscosity during foaming led to gas entrapment and larger, more irregular cellular structures. Overall, this work demonstrates an effective strategy for valorizing industrial byproducts into high-performance, sustainable RPFs.

The growing issue of electromagnetic pollution has generated a significant demand for multifunctional wearable textiles with electromagnetic wave (EMW) absorption. In this study, a multifunctional conductive cellulose-based composite fiber has been fabricated by wet spinning. A continuous conductive layer composed of polypyrrole (PPy) and carboxylated multiwalled carbon nanotubes (c-MWCNTs) was uniformly deposited on the surface of regenerated cellulose fibers (RCF) through in situ polymerization. The electrical conductivity of the resultant fibers could be improved to 127.12 S/m, benefiting from the addition of c-MWCNTs. Owing to multiple interactions between PPy and c-MWCNTs, including physical adsorption, hydrogen bonding, and π–π conjugation, the as-obtained composite fibers showed excellent electrical conductivity stability in abrasion resistance and washing durability tests. Due to the improvement in impedance matching by a conductive network and multiple loss mechanisms, the composite fibers exhibited excellent EMW absorbing properties with an excellent minimum reflection loss (RLmin) of −43.46 dB and a broad effective absorption bandwidth (EAB) of 7.95 GHz. Additionally, the composite fibers also displayed remarkable antibacterial activity against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli), as well as outstanding sensing performances for monitoring pressure with a high sensitivity of 1.10 kPa –1 over a range of 0–10 kPa.

The fabrication of high-performance hollow-fiber membranes (HFMs) can be effectively achieved through nanomaterial-based surface modification. However, achieving a uniform deposition of nanomaterials onto the curved surface remains a challenge. In this work, we have developed a pressure-driven, liquid-phase continuous deposition method to construct oxidized bacterial cellulose (BC) nanofibers onto HFMs in a layer-by-layer way. By controlling the oxidation time and deposition time, the Immunoglobulin G (IgG) rejection rate increases progressively from 50% to 90.1%, while the water permeance correspondingly decreases from approximately 1500 L m −2 h −1 ·bar −1 to 438.2 L m −2 h −1 ·bar −1 . The introduction of polyethylenimine (PEI) as a property regulator not only strengthens the crosslinking reaction but also further tunes the membrane properties. The oxidized BC membranes achieve a flux recovery ratio (FRR) of 64% in the cyclic filtration tests, which is 4 times that of the pristine substrates. The water permeance of the oxidized BC membranes can still be maintained above 80% of its initial value in the long-term filtration test. Moreover, the consumption of oxidized BC is as low as 1.77 g m −2 for modifying HFMs, which further enhances the process sustainability of HFMs fabrication.

Improving the interfacial compatibility between cellulose and poly(butylene adipate-co-terephthalate) (PBAT) is critical for enhancing the performance of PBAT-based composites. Here, microcrystalline cellulose (MCC) was homogeneously silanized at the molecular chain level usingt-hexyldimethylchlorosilane (TDMS-Cl) as the modifier, yieldingt-hexyldimethylsilylated cellulose (TDMS-Cell). TDMS-Cell/PBAT composite films were then prepared by solution blending and casting in tetrahydrofuran (THF). Structural characterizations confirmed the successful grafting of TDMS-Cl onto cellulose chains, resulting in TDMS-Cell with a degree of substitution of approximately 2. Microstructural observations combined with thermal analysis revealed that TDMS-Cell exerted a dual effect on the crystallization behavior of PBAT: it acted as a heterogeneous nucleating agent that increased the crystallization temperature, while the pronounced steric hindrance simultaneously suppressed crystal growth. Mechanical testing showed that simultaneous strengthening and toughening were achieved at an optimal TDMS-Cell loading of 3–5 wt%. Specifically, the tensile strength increased from ~16 MPa for neat PBAT to 21 MPa (31.25% improvement), and the elongation at break increased from ~700% to 964% (37.7% improvement). In addition, the incorporation of an appropriate amount of TDMS-Cell effectively enhanced the surface hydrophobicity of the composite films. At higher filler loading, however, solvent evaporation-induced phase separation led to self-aggregation of TDMS-Cell, which in turn deteriorated both the mechanical properties and surface hydrophobicity of the composites. Overall, this work systematically elucidates the structure–property relationships of silanized cellulose/PBAT composites in a homogeneous solution system, providing a rational basis for interfacial design and property optimization of PBAT/biomass-based composite materials. The prepared TDMS-Cell/PBAT composite films with balanced mechanical strength, tunable crystallization behavior, and improved surface hydrophobicity exhibit great potential for practical applications in high-performance flexible packaging materials, functional film substrates, lightweight composite structural components, and tunable hydrophobicity coating substrates.

The development of catalyst that workable homogeneously in reaction and recoverable heterogeneously in separation remains a challenge. We designed functionalized cellulose featuring malononitrile carbanion ion pair as a bifunctional catalyst for the cycloaddition of CO₂ to epoxides (CCE) reactions. The malononitrile (MNH) group was regioselectively anchored on the C-6 position of the anhydrous glucose unit of the cellulose backbone (Cell-MNH), and subsequently deprotonated with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) yielding catalyst Cell-[MN][DBUH], which exhibited excellent catalytic activity in CCE reactions of styrene oxide under conditions of 120 °C, 1.0 MPa, and 8 h, with catalyst loading of 1.5 mol%, achieving a yield of 93% and a selectivity of 94%. A bifunctional catalytic mechanism was proposed in which the carbanion attacked the CO₂ and the 1,8-diazabicyclo[5.4.0]undec-7-enium (DBUH) as an H-bond donor activated the epoxide. NMR titration experiments validated the role of DBUH in coordinating to epoxide through hydrogen bonding, and 13 C NMR spectra revealed a carbonate intermediate derived from malononitrile carbanion and CO 2 . The catalyst was homogeneous at 120 °C during the reaction but precipitated upon cooling due to the inter-chain attractions of the positive and negative ions, allowing easy filtration and recycling. The catalyst maintained robust by yields of 82%–97% and selectivity of 92%–99% through five recycles. This lignocellulose-based ion pair organocatalyst enables efficient homogeneous catalysis with heterogeneous recovery, offering potential design and broad applicability.

Environmentally friendly, sustainable, and widely available bio-based flame retardants provide an effective route for flameretardant functionalization of recycled cellulose materials. In this study, coaxial wet spinning is employed to encapsulate cellulose as the core with alginate as the shell. Coagulation in a Ca²⁺-containing bath enables simultaneous cellulose regeneration and in situ ionic crosslinking of sodium alginate (SA). With an optimized structural design, stable, all-bio-based core-sheath flame-retardant fibers (CAF) are constructed. The effects of sodium alginate concentration in the shell on fiber morphology, mechanical properties, and flame retardancy are systematically investigated. The resulting CAF markedly enhance flame retardancy while maintaining high mechanical properties, achieving a limiting oxygen index (LOI) of up to 32%. Compared with regenerated cellulose fibers (RCF), the peak heat release rate (PHRR) decreases by over 70%. Structural and thermal analyses reveal that the calcium alginate shell decomposes at the early stage of combustion to form a CaO/CaCO3-carbon composite protective layer, which effectively impedes heat and oxygen transfer and enables highly efficient flame retardancy. This work provides insights into the design and fabrication of high performance bio-based flame retardant regenerated cellulose fibers.

CMC/Ag-MOFs-CIN exhibited excellent mechanical and antioxidant capability. • CMC/Ag-MOFs-CIN exhibited controlled-release capability. • The film inhibited the growth of spoilage microorganisms in Lactifluus volemus . • The composite film can extend the shelf life of Lactifluus volemus . To extend shelf life of Lactifluus volemus, Ag@MOF loaded with cinnamaldehyde (CIN) was prepared and embedded into carboxymethyl cellulose (CMC) to develop antimicrobial films. The physicochemical properties of composite films were evaluated, along with their practical performance in Lactifluus volemus preservation. Compared with the CMC film, the CMC/Ag@MOF-CIN film exhibited better performance, including enhanced mechanical strength, barrier property, and antioxidant capacity, while showing reduced moisture content and water solubility. The CMC/6Ag@MOF-CIN composite film demonstrated 16.71% increase in tensile strength and 55.47% increase in elongation at break. The water vapour permeability decreased to 0.22 ± 0.01 g·mm/m 2 ·h·kPa, while oxygen permeability dropped to 18.67 ± 0.29%. Notably, antimicrobial and antioxidant properties improved by 68% and 45.49%, respectively. The composite films also exhibited controlled-release functionality. When applied to Lactifluus volemus preservation, the composite films effectively reduced weight loss, maintained higher activities of antioxidant enzymes, suppressed the activities of lipid peroxidation-related enzymes, and inhibited the growth of spoilage microorganisms. These findings demonstrated the potential of the CMC/Ag@MOF-CIN composite films as active packaging materials for Lactifluus volemus mushroom and other perishable foods.

A cellulose‑based Salisbury‑screen composite achieves 90.8 dB EMI shielding at 1.3 mm. • The screen provides strong reflection and destructive interference for high shielding. • It combines low emissivity and thermal insulation for excellent infrared stealth. The development of materials that seamlessly integrate electromagnetic interference (EMI) shielding and infrared stealth is of vital importance in addressing the challenges of complex electromagnetic environments and advanced multi-spectral detection. However, conventional metallic spectral defense materials suffer from high thermal conductivity and high density, making it difficult to meet the requirements for lightweight, high-performance materials. Herein, we incorporated the classic Salisbury screen structure into cellulose-based composites to overcome this problem. The composite featured a “conductor-insulator-conductor” architecture consisting of a cellulose nanofiber (CNF)/metal carbides/nitrides (MXene) film as the conductive layer and a CNF/gelatin aerogel as the insulating layer. This design exploited high interfacial reflection and phase-delay‑induced destructive interference, achieving an EMI shielding effectiveness of up to 90.8 dB at a thickness of only 1.3 mm. Simultaneously, the Salisbury screen configuration inherited the low infrared emissivity of MXene and the thermal insulation capability of the aerogel, substantially reducing the radiation temperature of the hot target surface and exhibiting outstanding infrared stealth performance. By modulating a sustainable cellulose platform with a classic wave‑interference architecture, this work establishes a new paradigm for next‑generation spectrally compatible defense materials that combine high‑performance EMI shielding and infrared stealth in a lightweight, eco‑friendly composite.

Sustainable wearable protective textiles integrating mechanical protection, monitoring, and visual feedback are desirable for healthcare and personal protection. However, multifunctional integration remains challenging because rigid inorganic fibers are difficult to integrate with conductive polypyrrole (PPy) and cellulose-based layers. Inspired by climbing plants, a biofermentation-induced cellulose integration strategy was developed to construct a basalt textile. Polypyrrole-coated basalt fabric was biofermented with bacterial cellulose (BC) to form a basalt/PPy/BC composite (BPB), the primary platform for mechanical protection and piezoresistive sensing. A self-assembled cellulose nanocrystal (CNC) layer was deposited on BPB to obtain basalt/PPy/BC/CNC (BPBC), adding structural-color feedback while retaining electrical responses. BPB exhibits an air permeability of 472.3 mm·s −1 , high mechanical robustness (maximum tensile force of 1390.6 N, 438.2 N bursting force, 24.4 N puncture force), good impact resistance (71.64% attenuation after 50 consecutive impacts), and piezoresistive sensing (−0.0448 and −0.0222 kPa −1 ). With the assistance of a one-dimensional convolutional neural network (1D-CNN), the platform enabled real-time hazard warning (98.3% within-dataset accuracy).

A liquid metal–wood hybrid was constructed via Pickering emulsion engineering. • CNC-stabilized liquid metal droplets enabled uniform infiltration into wood. • In situ droplet coalescence generated a continuous conductive pathway. • Multiple functionalities were achieved in a single bio-based material platform. • The strategy offers a new route for sustainable structural electronic materials. Wood, as a renewable and mechanically robust bio-based material, holds great promise for advanced functional applications; however, its intrinsic electrical insulation severely restricts its applications in advanced electronic and energy systems. Here, we report a facile approach to fabricate multifunctional conductive wood by infiltrating liquid metal (LM) via cellulose nanocrystal (CNC)-stabilized LM Pickering emulsion (PE). A hierarchically porous cellulosic wood scaffold (CBW) with enlarged lumen structures, reduced cell wall thickness, and improved pore accessibility is constructed through the selective removal of hemicellulose and lignin, enabling efficient infiltration of LM nanoparticles. The CNC-stabilized LM PE droplets are employed as LM nanoparticles and are introduced into CBW via vacuum-assisted impregnation. Subsequent hot pressing is proposed to facilitate the formation of an interconnected conductive network through the pressure-induced coalescence of discrete LM droplets. The resulting conductive wood (DCBW@LM) exhibits a high electrical conductivity of 310.2 S m −1 , good Joule heating performance, efficient near-infrared photothermal conversion, and stable EMI shielding effectiveness of 25–30 dB in the X-band. Moreover, DCBW@LM demonstrates significantly enhanced mechanical strength and flame resistance properties. This work establishes a facile strategy to construct highly conductive, photothermal, EMI shielding, robust, and improved short-term flame resistance wood and integrate LM with porous materials for sustainable, high value-added, and multifunctional applications.
