Multi-stimuli-responsive actuators attract significant interest due to their flexibility and adaptability to complex environments. However, achieving controllable response directionality and complex programmable deformation remains challenging. In this study, a humidity- and UV–visible light-responsive base film was developed using cellulose nanofibrils (CNF)/polyvinyl alcohol (PVA) functionalized with 4-hydroxyazobenzene (Azo). An asymmetric multi-stimuli-responsive composite film was fabricated via sequential coating of a polyimide (PI)/lignin oligomer (LIG) blend solution onto this substrate, exhibiting excellent dual humidity-light responsive deformation. The PI/LIG coating demonstrated excellent compatibility with the substrate, endowing the composite with excellent photothermally driven deformation and enhanced thermal stability. Under near-infrared (NIR) irradiation (100 mW/cm 2 , 60 s), the irradiated surface reached a maximum temperature of 64.07 °C. The actuator exhibited a moisture response sensitivity of 0.206 cm −1 /%RH −1 , along with excellent reversibility and remarkable responsiveness to sunlight, LED light, and NIR light. The distinct interfacial composition and response gradients enabled controllable deformation directions under moisture and light stimuli. Furthermore, stimulus-driven 2D-to-3D structural transformations, including grasping, lifting, and hinge-like motions, were achieved through diverse patterning strategies. This work provides a rapid and scalable approach for developing programmable patterned actuators with sophisticated deformation capabilities based on sustainable carbohydrate-derived materials.

Nanozymes are nanomaterials designed to mimic the catalytic functions of natural enzymes, offering advantages such as enhanced stability, tunability, and scalability. Although precise control over the spatial arrangement of catalytic centers is essential for maximizing nanozyme activity, it remains a fundamental challenge in nanozyme design. Here, we present a supramolecular strategy to achieve molecular-level engineering of catalytic centers by grafting hemin onto monodisperse cellulose oligomers (MCOs). The crystallization-driven self-assembly of MCOs directs the spatial organization of hemin while preventing its detrimental aggregation. Systematically tuning of the cellulose chain length reveals that a degree of polymerization (DP) of 6 optimally balances supramolecular packing and increased availability of active sites, whereas shorter (DP1) and longer (DP20) chains compromise catalytic performance due to aggregation or decreased substrate binding affinity. Structural analyses reveal that chain-length-directed crystallization governs nanozyme morphology, aggregation behavior, and catalytic performance. Through this approach, we achieve an approximately 500-fold enhancement in catalytic efficiency over free hemin, while structural analyses elucidate the role of chain-length-dependent crystallization in governing nanozyme morphology and performance. This study establishes transferable cellulose-based supramolecular strategy for engineering high-performance nanozymes with broad applicability across diverse catalytic systems.

The preparation of stable and efficient cellulose-based oil/water separation membranes is of great significance in solving the problem of industrial oily wastewater. Herein, rod-like hydroxyapatite (HAP) modified microfibrillated celluloses (MFCs) are used to form the fibrous framework to produce a microporous PDMS-MFC-HAP membrane. The membrane shows good superhydrophobicity with a water contact angle of 151.6°. It exhibits the oil-water separation performance for various water-in-oil emulsions. The separation flux of the membrane is up to 3665.3 L·m −2 ·h −1 ·bar −1 under 0.5 bar pressure with a separation efficiency of over 99.6 %. The PDMS-MFC-HAP membrane could maintain a high separation efficiency of 98.6 % after 20 cycles. This study provides a simple and effective method to fabricate cellulose-based superhydrophobic membranes, which have a greater potential to achieve oil-water separation for oily wastewater treatment with high efficiency.

The eco-friendly cellulosic paper-based mulch film has become an alternative to petroleum-based plastics. However, the integration of black, hydrophobic and high mechanical performances into cellulose mulch film still remained challenge. Herein, multifunctional (P/SLS-Fe/CA) black mulch film with the sandwich structure was designed by layer-by-layer assembly (LBL) strategy using filter paper (P) as the substrate, sodium lignosulfonate chelated with iron (SLS-Fe) as black factor and cellulose acetate (CA) as the hydrophobic layer. The quinone structure formed by the chelation and redox reaction between Fe 3+ and SLS induced the color change from brown-yellow to black of lignin. Moreover, the dynamic reversible physical bonds between P, SLS-Fe and CA endowed the composite with enhanced mechanical performance. The dry and wet tensile strength of the composite were 1.6 times and 21.3 times higher than pristine filter paper, respectively. The water contact angle increased from 58.4º for pure filter paper to 138.7º for the optimized P/SLS-Fe 4 /CA. Furthermore, the prepared black paper-mulch has low water vapor transmittance, heat preservation properties and good water resistance, which promote the growth of cabbage seeds. This work provides a prototype for the design and preparation of black cellulose fiber base membrane, and promotes the green development of agriculture.

In this study, a green lubricating grease was prepared based on cellulose and epoxidized soybean oil (ESO). The cellulose extracted from the corn stover was functionalized using diphenylmethane diisocyanate (MDI), which enhances its compatibility and thickening ability in non-polar oil, and subsequently dispersed in ESO to form a stable gel-like bio-based grease. The functionalized surface of cellulose was characterized by FTIR, SEM, and XRD. And the rheological and tribological characteristics of the prepared bio-based grease were discussed. The superior lubricity and anti-wear properties of our bio-based grease are demonstrated by its lower friction and diminished wear relative to commercial lithium-based formulations. This work provides practical guidance for designing environmentally friendly grease for sustainable lubrication.

Low-density lipoprotein (LDL) plays a crucial role in the development of cardiovascular disease. Lowering the level of LDL is an effective therapeutic strategy for treating cardiovascular disease. Here, we developed a facile and robust method to prepare carboxymethyl cellulose beads (CMCBs) for selectively adsorbing LDL. CMCBs had plentiful carboxyl groups and large numbers of nanopores on their surface. The in vitro assay reveals that CMCBs had a high LDL adsorbing capability of 7.67 ± 0.16 mg/g, owing to the carboxyl group-induced electrostatic adsorption and the nanopore-mediated trapping effect. CMCBs also possessed the excellent mechanical strength to resist the impact of rushing blood. Moreover, CMCBs were highly blood-compatible and had anticoagulant activity. The in vivo experiment reveals that LDL were significantly reduced from 15.02 ± 1.62 to 9.35 ± 1.71 mmol/L after blood perfusion using CMCBs, while minimal side effects were detected for the blood routine parameters. The study provides an easy-to-fabricate LDL adsorbent for selective and efficient clearance of LDL in hemoperfusion.

Currently, toughening poly(lactic acid) (PLA) without reducing its strength and modulus is still challenging. Fortunately, this problem could be addressed by incorporating cellulose nanocrystals grafted with epoxidized soybean oil (CNCs-g-ESO) into the PLA matrix. The percolation threshold for uniform dispersion of the CNCs-g-ESO in the PLA matrix was about 0.8 wt%. The loading made the elongation at break and tensile fracture energy of the PLA composite film increase to 26.5 and 11.26 from 3.7% and 0.96 MJ.m −3 , respectively, concerning the neat PLA. Meanwhile, it also resulted in a 4.7% and 12.4% increase in the tensile strength and Young's modulus, respectively. Additionally, the initial decomposition temperature (T 5% ) of the PLA composite increased to 334.9 from 316.1°C after incorporating the CNCs-g-ESO. Therefore, the CNCs-g-ESO, acting as an ESO-like plasticizer and a CNCs-like nucleating agent, is a potential nanofiller for reinforcing and toughening PLA.

Bio-based aerogels are sustainable and eco-friendly materials that have gained increasing attention. However, their development is hindered by complex technological processes and unsatisfactory mechanical properties. To obtain a multi-scale hierarchical micro-meso porous composite aerogel with extraordinary thermal insulation and mechanical properties via simple and facile preparation process, we used oxidized cotton linter fiber (CF) as the skeleton and reinforcement, oxidized microcrystalline cellulose (MCC) as the supporting and filling matrix, and PVA as the crosslinking agent and a good glue to enhance the interaction between CF and MCC, and the porous network of the composite aerogel. The composite aerogel is very light, strong, and flexible. The best obtained composite aerogel has a apparent density of only 67.5% of the pure cotton fiber composite aerogel (CF 0 ), a maximum compressive stress of 1.22 MPa, which is 22 times higher than the pure microcrystalline composite aerogel (MCC 0 ), and a thermal conductivity of 0.0335 W/m.K, which is 89% lower than CF 0 . These properties make the composite aerogel suitable for various thermal insulation applications, such as protective clothing for extremely cold environment.

Nanofluidic membranes utilize selective ion transport to capture osmotic energy from salinity gradients, efficiently converting it to electrical energy. However, traditional nanofluidic material synthesis still encounters challenges, including low charge density, high ion transport energy barriers, and limited current output. Here, we present a composite membrane consisting of hole-enriched graphene oxide (HGO) and cellulose nanofibers (CNF), engineered to enhance ion transport and energy conversion. HGO facilitates direct ion transfer through the nanopore within lamellar layers, effectively reducing the transmission distance and lowering the energy barrier for ion movement, thus enabling faster ion transfer between layers. CNF, on the other hand, offers robust mechanical strength and numerous active groups, imparting high ion selectivity to the nanoporous membrane. An osmotic energy generator utilizing the HGO/CNF membrane achieved a peak power density of 1.25 W m–2. Notably, the cationic transference number and energy conversion efficiency peaked at 0.84 and 23.64%, respectively, under a 500-fold concentration gradient. Additionally, the HGO/CNF composite membrane exhibits a robust tensile strength of 78.51 MPa, underscoring its excellent mechanical properties. The above results suggest that this highly ion-selective and energy-efficient composite membrane presents a promising avenue for advancing osmotic energy research.

Solid acid catalysts have attracted much attention in cellulose hydrolysis due to their high product selectivity, easy preparation and reusability. However, most current researches only focus on modifying their surface functional groups but overlook the impact of carrier shape on hydrolytic performance. Herein, we synthesize a series of rod-shaped silica with varying sizes for cellulose hydrolysis to analyze the shape mode to enhance the breaking of cellulose structure during solid-solid reaction. Experimental results show rod-shaped silica produces particular penetrating mode to enter into the interior of cellulose and thus causing strong disruption. This mode quickly disrupts the aggregated structure of cellulose, fragmenting it in a short time. The cellulose fragments are rapidly converted to glucose in a 0.02 M H + solution. This process achieves an 83.92 % cellulose conversion rate and a 52.98 % glucose yield. The discovery suggests a new strategy to design one-dimensional solid catalyst for the efficient hydrolysis of cellulose to sugar.

High adsorption capacity, high adsorption rate and reusable adsorbents are urgent needed for removing heavy metals from wastewater. In this study, porous sodium alginate/cellulose nanofiber (SA/CNF) composite hydrogel microspheres were prepared by combining sodium alginate with cellulose nanofibers by microfluidics technology and adding polyethylene glycol (PEG) as pore making agent. The SA/CNF composite hydrogel microspheres could efficiently adsorb heavy metals (Pb 2+ , Cu 2+ and Cd 2+ ) in wastewater. The influencing factors of adsorption process, including pH, temperature, initial concentration, coexisting ions and aquatic environments, were systematically discussed. The adsorption process was more consistent with Langmuir isotherm model and pseudo-second-order model in batch system, indicating the adsorption process was mainly chemical adsorption. The adsorption capacity to Pb 2+ obtained by Langmuir model was as high as 544.66 mg/g at 20 °C. Fixed-bed column adsorption experiments demonstrated the excellent performance of the as-prepared SA/CNF microspheres for treatment of the flowing wastewater in a column system. Overall, a highly practical adsorption process based on hydrogel adsorbents was developed for the removal of heavy metals from actual wastewater.

Levofloxacin (LEV), a widely used quinolone antibiotic, persists in aquatic environments and is difficult to degrade. Its significant toxicity can exacerbate the spread of antibiotic resistance through environmental transmission, making it a pollutant that urgently requires attention. As a new type of porous adsorbent material, hydrogels offer abundant adsorption sites during the adsorption process, making them widely used in water pollution treatment. In the present work, sodium periodate was used to oxidize cellulose to synthesize easily modified diacetyl cellulose (DAC). Subsequently, hyperbranched polyamides (HBP) containing multiple amine groups were ammoniated and crosslinked with DAC. Hyperbranched ammoniated double aldehyde cellulose hydrogels (HBP-DAC@SA) featuring a three-dimensional porous structure were prepared. The microstructure of HBP-DAC@SA was analyzed to investigate the adsorption performance of HBP-DAC@SA on LEV pollutants. The effects of synthesis temperature, pH, and HBP-DAC dosage on the adsorption properties of LEV were investigated through orthogonal experiments. The adsorption capacity of HBP-DAC@SA for LEV reaches up to 216.72 mg·g −1 . The adsorption kinetics and adsorption isotherm data are consistent with the quasi-secondary adsorption model and the Langmuir isothermal adsorption model, respectively. Furthermore, the adsorption capacity of HBP-DAC@SA remained at 80 % of its initial capacity after 14 cycles of adsorption/desorption. HBP-DAC@SA is easily recyclable and exhibits excellent reusability. Consequently, it can serve as an effective adsorbent material for treating LEV pollution.
