In this study, a pilot-scale straw cellulose-based polyurethane biocomposite modified with phytic acid (PA) and Fe 2 O 3 (SC/PA/Fe) was developed through an eco-oriented and scalable fabrication route, and its flame retardance, physical properties, colour characteristics, and application potential were systematically investigated. The composite was fabricated via sequential spray-assisted delignification, stepwise spray impregnation of PA and Fe 2 O 3 , high-shear reactive blending, and room-temperature press molding. The optimized SC/PA/Fe achieved a limiting oxygen index (LOI) of 27.9 and a total smoke release (TSR) of 48.89 m 2 /m 2 , demonstrating markedly improved fire safety relative to untreated SC. Mechanistic analysis indicated that the synergistic effect of PA and Fe 2 O 3 facilitated the formation of a stable phosphorus-rich char layer during combustion, which enhanced thermal stability and reduced smoke generation. In addition, interfacial cross-linking between PA and the -NCO groups of TDI helped preserve the structural integrity of the composite, resulting in a tensile strength close to 1.0 MPa and a bending strength of 5.2 ± 0.2 MPa. Based on Material Driven Design (MDD), the warm red-toned appearance together with the improved flame-retardant performance suggests that SC/PA/Fe is a promising candidate for non-load-bearing interior applications, such as furniture surfaces and decorative panels.

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.

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.

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.

The electrochemical deposition of metallic lithium, though a promising anode for next-generation high-energy batteries, is challenged by the formation of an unstable solid-electrolyte interphase (SEI), leading to dendrite growth and posing safety risks and limiting life cycles. Traditional strategies such as electrolyte additives offer improvements but struggle under harsh conditions due to insufficient durability of concentration and high flammability. Inspired by sustained drug-delivery systems, we introduce ultrathin (5 μm) cellulosic composite paper separators that enable the controlled release of antimony oxychloride (SbOCl) nano-additives via sustained first-order release kinetics from the intermolecular entanglement within the cellulose fibers. These additives form Li 3 Sb clusters at the anode interface, enhancing SEI stabilization and uniformity of lithium deposition, thereby mitigating dendrite formation. Integrating SbOCl and cellulose effectively suppresses dendrites and improves battery safety through flame-retardant (limiting oxygen index: 39.27%) and thermal stability. The Li anodes with the paper separator achieve over 6000 h of stable cycling in symmetric cells and over 250 cycles in full cells with NCM622 cathodes, realizing an energy density of 368.65 Wh kg⁻¹ (904.90 Wh L⁻¹). Ah-level pouch cells demonstrate robust safety in nail penetration tests, underscoring the potential of this method to advance safe, sustainable, high-energy lithium metal batteries (LMBs) for future wearable applications.

Cellulose-based insulation paper is widely used in high-voltage equipment, but its limited thermal conductivity and dielectric strength restrict reliable performance under elevated temperatures and strong electric fields. In this work, a dual-phase composite paper is developed by incorporating nano-ZnO and polyimide (PI) into a cellulose matrix, guided by molecular dynamics (MD) simulations. The combined fillers improve interfacial compatibility, suppress void defects, and establish continuous thermal pathways together with stable insulating barriers. Simulation predictions of enhanced thermal transport, charge suppression, and mechanical reinforcement are verified by experiments. The optimized formulation containing 3 wt% nano-ZnO and 6 wt% PI achieves a thermal conductivity of 0.294 W·m⁻¹·K⁻¹, a tensile strength of 72.12 MPa, corresponding to 87.26% and 41.02% improvements over pure cellulose (P0). Meanwhile, the breakdown strength increases from 60.22 to 73.51 kV·mm⁻¹ (+22.07%), and the relative permittivity and dielectric loss tangent decrease to 2.49 (−40.86%) and 0.46% (−43.21%). These results demonstrate that the dual-filler strategy provides a structurally compact and functionally stable composite architecture, enabling simultaneous enhancement of thermal, mechanical, and dielectric properties. This study confirms the effectiveness of simulation-guided design in accelerating the development of multifunctional cellulose-based insulating materials and highlights their potential for application in next-generation high-voltage power systems.

Despite excellent biocompatibility, hyaluronic acid (HA) exhibits poor 3D printability, insufficient mechanical properties, and uncontrolled degradation in tissue engineering applications. This study developed HA-based biomaterial inks by integrating cellulose materials, including cellulose nanocrystals (CNC), carboxymethyl cellulose (CMC), and methylcellulose (MC), into a methacrylated hyaluronic acid matrix. The influence of cellulose material structure and concentration on the rheological characteristics, 3D printability, and temporal evolution of physical properties during degradation was systematically elucidated. Results demonstrated that CNC served as a nano-reinforcing phase to enhance the mechanical properties of hydrogels, while CMC and MC functioned as rheological modifiers to improve pre-crosslinking rheological behavior. The incorporation of cellulose materials at varying concentrations into the HA matrix proved to be an effective strategy for modulating the mechanical performance of hydrogels. Upon photo-crosslinking, the prepared biomaterial inks produced intact printed structures with high mechanical properties and stability. The HA/CNC hydrogels retained approximately 83% of initial strength by day 14, maintaining load-bearing capacity and structural integrity throughout degradation. This work elucidates the synergistic mechanisms by which cellulose materials regulate multi-scale properties of HA biomaterial inks, providing a theoretical foundation for developing high-fidelity, mechanically tunable, and degradation-controllable 3D-printed tissue engineering scaffolds.

Hybrid CMC films with Ag/Cu/CuO nanoparticles were prepared via film casting method. • Comprehensively study water permeability, solubility, antimicrobial, and cytotoxic. • Enhanced mechanical strength and water-resistant of CMC-based films support food packaging. • A sustainable framework with strong potential for food packaging applications. Carboxymethyl cellulose (CMC), a renewable chemically modified material derived from rice husk, is a promising biopolymer matrix for biodegradable films and shows strong potential for high-performance, environmentally friendly packaging. This study investigates the synthesis and properties of CMC-based packaging films, including those derived from CMC, metal nanoparticles (Ag, Cu/CuO), and/or metal–organic coordination systems. Particular attention is given to key critical for food packaging applications, such as mechanical strength, transparency, water vapor barrier performance, antimicrobial activity against both Gram-positive and Gram-negative bacteria. The successful preparation of the hybrid films was evaluated using FT-IR, XPS, XRD, and TGA techniques, while solid content and swelling ratio were also determined. The results clearly indicated significant improvements in the thermal and mechanical performance of the hybrid nanocomposite films, with tensile strength and elongation at break increasing by 233–286% and 107–132%, respectively. The films showed improved moisture resistance and CMC-based hybrid films containing metal–organic coordination system exhibited significantly lower humidity transmission compared to unmodified film. The hybrid nanocomposite films exhibited the highest zones of inhibition of 10.6 ± 0.7 mm against E. coli and 11.2 ± 0.2 mm against S. aureus , indicating significant antibacterial activity resulting from the synergistic bacterial growth inhibition effects of Ag and Cu/CuO. The utilization of agricultural by-products enabled the sustainable fabrication of hybrid CMC-based packaging films, which demonstrate strong potential to meet functional and regulatory requirements for food packaging while supporting the transition toward sustainable and circular packaging systems.

Aminosilane functionalization formed stable Si–O–C/Si–O–Si covalent bonds. • Cross-linked siloxane networks enabled uniform reinforcement and aging resistance. • Paper surface property differences caused varied enhancements. • APTMS-BC improved performance across paper surfaces with varying effects. • Reinforced papers showed superior resistance to humid aging and yellowing. Bacterial cellulose (BC) is a promising nanofibrous material for paper conservation, but its inherent hydrophilicity limits interfacial adhesion and durability under humidity. Hence, we employed aminosilane functionalization using 3-aminopropyltrimethoxysilane (APTMS) to construct Si–O–C/Si–O–Si covalent bridges and extend hydrogen-bond networks, thereby reducing surface energy and enhancing the interaction at the BC-fiber interface. Structural analyses (FTIR, XPS) verified successful grafting through new Si–O–C/Si–O–Si signals and an O/C ratio reduction from 0.51 to 0.40, while thermogravimetric analysis revealed higher thermal stability, indicating a denser cross-linked network. The grafting ratio reached a maximum of 12.97% at a BC: APTMS ratio of 1:8, with optimal functionalized conditions identified at 4 h and 45−55°C. Under these conditions, tensile, tear, and folding strength of APTMS-BC reinforced paper (B# newsprint) rose by 68.55%, 128.81%, and 275.94%. Moreover, APTMS-BC significantly improved the mechanical properties and water resistance of paper samples with different interface properties while inducing negligible changes in appearance. During moist heat aging, the strength and yellowing of APTMS-BC reinforced papers demonstrated superior long-term durability. These results establish APTMS-BC as a versatile nanocoating that offers both mechanical reinforcement and environmental protection, providing a promising strategy for sustainable paper conservation.

This study investigated the effects of loadings of cellulose nanocrystals (CNC) extracted from jute fibers on the chemical, mechanical and thermal properties of the Epoxy matrix. The CNC/Epoxy composites were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectrometry, tensile tests, dynamic mechanical analysis, and thermogravimetric analysis. Experimental results showed that the tensile strength, modulus, and work of fracture showed a statistically significant increase from 1 to 5 wt.% CNC loading. In addition, TG measurements revealed that the onset temperature (Tonset) and temperature at maximum decomposition rate (Tmax) for composites decreased compared to neat epoxy with increasing CNC concentration. Dynamic mechanical analysis studies showed that the storage modulus values at 35 °C and 120 °C decreased for lower 1 wt% CNC content sample compared to neat epoxy, then increased for samples loaded with 3 and 5 wt% of CNC.
