The rise of additive manufacturing technology has enabled the personalization of cushioning materials. This study developed a cellulose-based hydrogel that can be 3D printed, featuring a crosslinked interpenetrating network (IPN) of hydroxypropyl cellulose (HPC)/methacrylic anhydride-modified polyvinyl alcohol (PVA-MA) reinforced with carboxylated cellulose nanofibers (CNF) and quaternized chitosan (HACC). Multiple characterization techniques confirmed the successful construction of the crosslinked interpenetrating network structure, and the relationship between the hydrogel's crosslinked network structure and its cushioning performance was investigated. We rigorously confirmed that sodium citrate solution post-treatment induces ionic crosslinking significantly boosts the cushioning performance of the hydrogels, via comparative analysis of PMHI and PMHI-Na samples. Specifically, at 50% compressive strain, it demonstrated an energy loss coefficient of 61.4%, a Young's modulus of 448.22 kPa, and a static minimum cushioning coefficient below 0.5. Its performance surpassed that of traditional commercial cushioning materials like expanded polyethylene (EPE) and expanded polystyrene (EPS). To address customized demands for cushioning packaging, the printability of hydrogels for additive manufacturing (3D printing) was systematically investigated. Hydrogels containing ethyl (2,4,6-trimethylbenzoyl) phenylphosphinate (TPO-L), a high-efficiency UV photoinitiator, demonstrated rapid curing rates while exhibiting compressive strengths up to 547.40 kPa and elongation at break up to 229.40%, enabling high-quality 3D printing. This work provides a promising approach to biomass-based cushioning materials with improved mechanical properties and 3D printability, advancing the large-scale application of biomass cushioning materials.

Nature has engineered hierarchical and heterogeneous lignocellulose structure, among which lignin significantly contributes to mechanical behavior due to its unique molecular structure and micro-distribution pattern. Inspired by this fact, we unveil the potential of intrinsic lignin to toughen and hydro-stabilize cellulose nanopaper (CNP)—a crucial advancement for its deployment in demanding structural applications. By examining CNPs assembled from nanofibrils with controlled variations in size distribution and lignin content, we show that an optimal level of intrinsic lignin simultaneously enhances both the elastic stiffness and inelastic deformability of CNP. This strengthening and toughening effect is attributed primarily to the significant influence of lignin on the topological structure and interfacial behavior of the constituent nanofibrils. In particular, we clarify the lignin-mediated toughening mechanism in CNP through a combined experimental-simulation approach: amorphous lignin undergoes conformational evolution during interfibrillar sliding, which effectively absorbs and dissipates energy, thereby significantly enhancing the toughness of the hierarchical cellulose matrix. Additionally, the hydro-stability of CNP is enhanced by lignin with intrinsic amphiphilicity, which plays a critical role in moderating interfacial wettability and thereby delaying the hygroscopic kinetics of cellulose assemblies. Therefore, this work presents a dual-purpose strategy that harnesses the inherent functionality of lignocellulosic components to simultaneously toughen and hydro-stabilize the resulting nanomaterials.

Citric acid was used to dissolve and crosslink chitosan, offering a green and environmentally friendly preparation route. • By introducing cellulose nanofibers, a highly stable 3D network scaffold was constructed. • The prepared cellulose nanofiber/sodium alginate/chitosan aerogel balls exhibited excellent structural stability. • The maximum adsorption capacity for the cationic dye methylene blue reached 1371.1 ± 54.8 mg/g. • Adsorption followed pseudo-second-order kinetics and Langmuir isotherm models. To develop sustainable materials for textile dye wastewater purification, this study utilized renewable biopolymers to fabricate cellulose nanofiber/sodium alginate (CNF/SA) hydrogel spheres via metal-ion crosslinking. Subsequently, chitosan was dissolved in an environmentally friendly citric acid solution and integrated into the CNF/SA matrix through crosslinking, followed by freeze-drying to obtain cellulose nanofiber/sodium alginate/chitosan (CNF/SA/CTS) aerogel spheres. Comparative characterization and adsorption performance studies revealed that the introduction of chitosan into the CNF/SA system formed a ternary composite material (CNF/SA/CTS) with a denser and more stable three-dimensional network structure, enriched with abundant functional groups, such as amino groups. This material maintained good structural stability and adsorption performance across a wide pH range and after multiple adsorption-desorption cycles. Notably, CNF/SA/CTS exhibited a strong adsorption capacity for various dyes, including methylene blue, crystal violet, methyl orange, and malachite green. The maximum adsorption capacity for cationic dyes reached as high as 1371.1 ± 54.8 mg/g, outperforming the corresponding CNF/SA binary material. The adsorption process followed pseudo-second-order kinetics and the Langmuir isotherm model, and was determined to be spontaneous and endothermic. This study confirms the significant potential of CNF/SA/CTS aerogel spheres as an ideal green adsorbent, highlighting the promising sustainable application prospects of biomass-based composite materials in wastewater treatment.

Catalytic pyrolysis for the targeted production of renewable phenol—which serves as a crucial oxygenated fuel additive for upgrading bio-oil stability and a key platform chemical in modern biorefineries—represents a vital pathway for advanced biomass valorization. Yet, the rapid deactivation of catalysts remains a critical bottleneck hindering its industrial bioenergy application. This study employs phosphoric acid-activated carbon (P-AC) as a solid acid catalyst to systematically explore the process conditions and multi-dimensional deactivation mechanism of phenol production from cellulose pyrolysis, with optimal phenol selectivity achieved at 500 °C and a catalyst-to-feedstock mass ratio of 1.0. Catalyst deactivation arises from the synergy of physical pore blockage and chemical degradation: physically, coke deposition acts as non-selective “blanketing” of pore channels, inducing proportional and systemic degradation of the entire pore structure; chemically, TPD and XPS correlative analyses confirm that medium-strong acid sites composed of C-O-PO 3 and C-PO 3 functional groups are critical to catalytic performance, and their loss not only blocks the main phenol formation pathway but also triggers the reoccurrence of upstream intermediates (e.g., ketones, furans) and activates downstream side reactions forming pyrans and esters, ultimately resulting in systemic deterioration of the entire catalytic reaction network. This work provides novel theoretical insights into understanding the complex deactivation behavior of carbon-based catalysts and designing targeted regeneration strategies.

Aqueous batteries offer inherent safety and low cost, but the inherently fixed physicochemical functionality and poor interfacial compatibility of existing binders limit their ability to boost positive electrode performance. Here we present a hydroxyl-chemistry regulation strategy that transforms cellulose, an abundant biopolymer on Earth, into a high-affinity, interfacially compatible binder that stabilizes high-capacity, shuttling-prone positive electrodes. By selectively opening the rigid cellulose ring structure within its molecular chains, we enhance dipole polarity, chain flexibility, and intermolecular hydrogen-bond density, thereby increasing functional-group accessibility and interfacial adhesion. These molecular-level modifications drive the formation of a dense nanofibrous network that conformally encapsulates active particles and anchors polyiodides, accelerating redox kinetics and reinforcing electrode stability. Iodine positive electrode incorporating the engineered binder deliver a reversible capacity of 150.9 mAh g −1 at 20 A g −1 , with pouch cells retaining 98.07% capacity after 3000 h at 0.2 A g −1 . The binder also enables layer-by-layer fabrication of high mass loading electrodes, and benefits other dissolution-prone positive electrodes such as V 2 O 5 . Overall, this work establishes a general and sustainable route for the molecular engineering of biopolymer binders, expanding their role in the design of advanced aqueous batteries.

Thermal insulation materials play a critical position in daily life and industrial processes, as they not only protect humans from cold environments but also reduce energy consumption and contribute to sustainable development. Biomass-based porous fibers, featuring excellent thermal insulation properties and environmental sustainability, demonstrate substantial potential in the field of personal thermal management. In this work, a series of cellulose acetate (CA)/thermoplastic polyurethane (TPU) porous fibers were prepared via a combination of wet spinning and freeze-drying techniques. The structure–property relationships among the preparation process, microstructure, and thermal insulation behavior were systematically investigated. Notably, at a CA/TPU mass ratio of 9/7 and a winding speed of 3.9 mm/s, the obtained porous fibers achieved a breaking stress of 2.84 MPa and a breaking strain of 7.41%. Such superior mechanical property not only ensures the stable continuous production of fibers during wet spinning, but also satisfy the tensile and weaving requirements of subsequent textile processing. Furthermore, the corresponding plain weave fabric exhibited optimal thermal insulation performance with a low thermal conductivity of 0.029 W/(m K). This work provides valuable guidance for the structural design and performance improvement of porous fibers, laying a solid foundation for their prospective applications in energy-efficient textiles.

Cellulose fibers derived from renewable biomass exhibit exceptional tensile strength through molecular alignment and dense packing, yet their toughness remains limited, typically below 50 MJ m −3 . Drawing inspiration from the helical nanoarchitecture of cherry bark, we introduce a bioinspired nano-orientation strategy to fabricate regenerated cellulose fibers with a biaxially oriented structure via a scalable microfluidic spinning technique. Combining experimental characterization and molecular simulations, we demonstrate that this biaxial nano-architecture effectively redistributes stress and suppresses crack propagation during deformation, achieving a remarkable fracture strain of 41% alongside a tensile strength of 553 MPa. This synergy yields a toughness of 184 MJ m −3 , exhibiting highly competitive performance relative to most previously reported cellulose fibers and synthetic polymers, and achieving a mechanical performance on the same order of magnitude as natural spider silk. Moreover, this enhancement extends seamlessly from single fibers to woven fabrics, highlighting its potential for sustainable, high-performance materials in textiles, automotive components, and aerospace applications. Our findings illuminate a design for overcoming the intrinsic brittleness of cellulose fibers, advancing their applicability as eco-friendly structural materials.

Sustained-release technologies for fragrance hold significant application value in the daily chemical, agricultural, and tobacco industries. However, conventional carrier systems such as nanoparticles, microcapsules, micelles, and inclusion complexes suffer from complicated preparation processes, poor scalability, and high costs. To address these challenges, we designed a facile and green fragrance sustained-release film system based on a hydrogen-bond-mediated cellulose–menthol network, which features simplified processing and a tunable structural architecture. The resulting composite films (HPMC@M and HEC@M) exhibited excellent film-forming ability, high menthol encapsulation efficiency (up to 90%) and a fivefold extension of the release period compared to free menthol. GC-MS and thermogravimetric analysis (TGA) revealed that the cellulose network effectively suppresses menthol volatilization, while SEM observations and XRD analysis confirmed a homogeneous porous structure that enables gradual diffusion. DFT calculations and FTIR analysis revealed that intermolecular hydrogen bonding between menthol and cellulose chains is the dominant retention mechanism, with HPMC exhibiting a stronger interaction energy (−25.27 kcal mol −1 ) than HEC (−22.18 kcal mol −1 ), which accounts for its superior release control. This environmentally benign, scalable, and low-cost approach provides a promising platform for the sustained release of lipophilic fragrances and functional volatiles in diverse industrial applications.

Replacing high-performance synthetic fibers with sustainable bio-derived alternatives is critical for mitigating microplastic pollution but remains limited by the inferior mechanical performance of biomass-derived fibers. Here, we present bioinspired cellulose metafibers (Meta-CFs) enabled by a scalable hydrodynamic twisting strategy, wherein an asymmetric microfluidic field precisely guides the formation of continuously twisted architectures within a chemically cross-linked network, thereby locking in the ordered configuration and markedly suppressing defect accumulation. Multiscale experiments and simulations reveal that this strategy promotes efficient stress delocalization and cooperative load transfer. The resulting Meta-CFs achieve an unprecedented maximum tensile strength of 3.29 GPa (average 3.06 ± 0.23 GPa) and a toughness of 349.5 MJ m −3 , simultaneously rivaling the strength of high-performance synthetic fibers and the toughness of natural spider silk. Furthermore, encapsulating multiple individual Meta-CFs with calcium alginate effectively scales up the bundle diameter while preserving GPa-level strength and full biodegradability. This upscaling strategy enables large-diameter structural applications, as demonstrated by durable trimmer lines that avoid the generation of persistent agricultural microplastic residues, thereby establishing a viable pathway toward high-performance, sustainable material alternatives.

Humidity-driven smart materials have attracted increasing attention due to their capability of autonomous actuation without external energy input, offering significant potential in soft robotics and adaptive systems. However, natural polymer-based actuators often suffer from insufficient mechanical strength and limited structural stability, which restrict their practical applications. In this study, a novel biomimetic water-driven actuator was developed based on silane-modified microcrystalline cellulose (KMCC) and fish bladder gelatin (FG). A bilayer anisotropic structure inspired by natural hygroscopic systems was designed, and the effects of KMCC content and structural parameters on deformation behavior were systematically investigated through experimental characterization and finite element simulation. The results demonstrate that the incorporation of KMCC significantly enhances the mechanical and thermal properties of the composite hydrogel. The tensile strength increased from 0.258 MPa (pure FG) to 0.477 MPa at 10% KMCC, while the thermal decomposition temperature improved by approximately 11.81 °C. The actuator exhibited excellent reversible deformation behavior, with a maximum bending curvature of 0.083 at 10% KMCC content. Increasing KMCC content led to reduced deformation amplitude but improved structural stability. Furthermore, the actuator achieved controllable twisting deformation, with a maximum torsion angle of 2.04π and deflection of 66.93 mm at a 20° layer angle. Finite element simulation results were in good agreement with experimental data, confirming the reliability of the deformation mechanism. he deformation mechanism is governed by moisture diffusion and hydrogen bond reconstruction, which induce anisotropic volume changes and interfacial stress mismatch in the asymmetrical structure. This study provides a feasible strategy for enhancing the performance of water-driven actuators through material interface modification and structural design, offering new insights for the development of high-performance smart materials in soft robotics and adaptive systems.

Developing sustainable and scalable personal thermal management textiles that simultaneously provide radiative cooling, moisture comfort, and responsible end-of-life management remains challenging. Here, we report a sustainable, scalable, and recyclable bamboo dissolving pulp-derived cellulose/SiO2fiber (CSF), fabricated by a wet-spinning process involving the dissolution and regeneration of cellulose and nano-SiO2. The resultant CSF exhibits a hierarchical interface-pore structure, which enhances solar scattering (up to 94.56% in 0.4–1.0 μm) by Mie scattering of nano-SiO2particles and multiple scattering at micro- and nanopore-induced air/cellulose/SiO2interfaces. By coupling high mid-infrared emissivity of 94.8% (8–13 μm), the CSF demonstrates average daytime sub-ambient cooling of 9.5 °C under hot and humid summer conditions. More importantly, the CSF presents a multiscale water-transport network that integrates molecular water capture (–OH groups), capillary infiltration (nanoscale interfaces between nano-SiO2and cellulose), and liquid spreading and evaporation (interconnected microchannels between fibers), which realizes larger liquid diffusion area and water-vapor transmission rate (7.55 cm2and 175.48 g m−224 h−1), compared to commercial cotton and polyester. In addition, the CSF demonstrates desirable soil-biodegradation capability, while the feasibility of closed-loop reuse is demonstrated through a single recycling cycle, supporting environmentally friendly wearable cooling textiles. The wet-spinning strategy paves the way for the construction of sustainable, scalable and recyclable fiber for thermal- and moisture-comfort textiles.

Stable rice protein liquids with a high protein concentration of 6.0 wt% were prepared. • A salt-free strategy was developed using cation-exchange resins to replace HCl. • The aggregation of RPs is significantly inhibited in an environment without NaCl. • The thermal stability of the RCs was improved through the interaction between RPs and CMC. • The stability and rheological properties of rice protein liquids were regulated by adjusting the mass ratio of RPs/CMC. Protein-polysaccharide complexation represents a unique paradigm for spatially arranging protein particles to formulate concentrated dispersions. However, this strategy is not applicable to hydrophobic rice proteins (RPs) with low solubility. The objective of this study is to develop a salt-free strategy for preparing high-concentration and stable RP liquids, suitable for high-protein foods. We first prepared uniform RP nanoparticles (29 nm) by cation-exchange resins (CERs) that released H + and replaced Na + while neutralizing OH − in an alkaline solution. Thus, the generation of NaCl was circumvented eliminating the self-aggregation of RPs. Then, the electrostatic interactions between RPs and an anionic polysaccharide, carboxymethyl cellulose (CMC), were enabled by CER-induced refolding of unfolded RPs. This strategy allowed us to create stable protein-polysaccharide complexes with a protein content up to 6.0 wt%, which were resistant to self-aggregation and had controllable rheological properties that are pivotal for designing high-protein foods.
