Mercerization and sizing constitute essential pretreatment protocols for optimizing the processability and wear performance of cotton gauze in textile manufacturing. Nevertheless, conventional methodologies relying on high-concentration alkali solutions and non-degradable sizing agents (e.g., polyvinyl alcohol) present critical challenges. To address these limitations, we developed an integrated cellulose/NaOH/urea ternary system (1 wt% cellulose, 7 wt% NaOH, 12 wt% urea) that synergistically achieves fiber mercerization, sizing, and in situ synthesis of silver nanoparticles (Ag NPs) through a single-bath process. Within this system, NaOH was used as a mercerizing agent, while cellulose derivatives served as triple functions: (1) as a green reductant for Ag + ions, (2) as a stabilizer of Ag NPs, and (3) as a biodegradable sizing matrix. Urea operates as a multifunctional adjuvant through [Ag(NH 2 ) 2 CO] + . Compared with Ag-NaBH 4 @GZ, the optimized Ag-140°C@GZ composite demonstrated exceptional functional integration: the attachment of Ag NPs was confirmed through characterization techniques, such as FTIR, XPS, and so on. Notably, the modified gauze still achieved complete sterilization of Escherichia coli within 4 h after 100 accelerated washing cycles. Crucially, functionalization preserved intrinsic textile characteristics with a minimal impact on vapor transmissibility (1079 g/m 2 /day) while enhancing tensile strength by 25.6%. Biosafety is confirmed via cyto-compatibility assessments. This efficient collaborative process has developed durable medical textiles while addressing issues of antibacterial performance, environmental sustainability, and industrial scalability.

Poly(ethylene oxide) (PEO) is widely employed as the matrix material for solid polymer electrolytes (SPEs) in lithium-metal batteries (LMBs). However, inherent drawbacks such as high crystallinity and excessive lithium-ion coordination effects severely hinder its practical applications. To address these limitations, this work develops an integrated polymerization-mixing-impregnation (PMI) strategy, fabricating a PACP-PEO@CF SPE through polymerizing of P(AN- co -PEGMA), mixing with PEO, and impregnating onto a cellulose framework (CF). Complementary density functional theory (DFT) calculations elucidate the critical role of PACP's functional groups in facilitating Li + transport. This approach simultaneously enhances Li + conductivity, dendrite suppression capability, and cycling stability in assembled PACP-PEO@CF-supported LMBs, effectively overcoming the intrinsic constraints of cellulose-based SPEs. It is impressive that the PACP-PEO@CF SPEs exhibits a high ionic conductivity of 1.95 × 10 −4 S cm −1 at 25 °C, a Li + transference number of 0.62, a wide electrochemical stability window of 5.6 V, and exceptional Li plating/stripping stability (>440 h at 0.1 mA cm −2 ). Furthermore, corresponding LMBs achieve stable cycling over 500 cycles at 0.5C and 45 °C. This study not only enhances lithium-ion conductivity through the molecular design of PACP polymer chains and their mixing with PEO, as supported by theoretical simulations, but also leverages the scaffold effect of CF to improve mechanical support and interfacial stability. This viable strategy further advances the application of biomass-derived materials in advanced energy storage technologies.

The loss and overuse of avermectin (AVM) on protecting plants pose a threat to ecosystems. To increase the efficacy of AVM, fluorinated sodium carboxymethyl cellulose (CMC-g-PHFBA) was synthesized by inducing poly 2, 2, 3, 4, 4, 4-hexafluorobutyl methacrylate (HFBA), and AVM was then enveloped in CMC-g-PHFBA (AVM@CMC-g-PHFBA) via hydrophobic interaction. According to the results, the samples exhibited desirable angle contact (min = 58.18°), retention rate (max = 60%, after water washing) and LHC (15.5 mg/cm2) on cucumber leaves. AVM@CMC-g-PHFBA also showed good storage stability with obvious Tyndall effect (size <240 nm and charge <–21 mV) for 11 days, with higher anti-UV property. The loaded AVM nanoparticles can release drugs for 95 h, which can be fitted to a zero-order model under different pH conditions for achieving a prolonged pharmacological action. Moreover, the samples have retained insecticidal activity. Collectively, CMC-g-PHFBA nanoparticles are promising delivery systems of AVM with the adhesive and sustained-release property.

Hydrogels based on cellulose-graft-poly (acrylic acid) copolymers (C-g-AA) were synthesized by graft copolymerization in a phosphoric acid solvent. Fourier transform infrared (FT-IR) spectra confirmed the structure of the C-g-AA. The adsorption behaviors of the hydrogels for Cu(II) and Ni(II) were investigated. The results showed that their adsorption capacity increased as the initial concentrations of metal ions and the pH value of the solution increased. Freundlich and Langmuir isotherm models were employed to analyze the data from batch adsorption experiments. The results indicated that there were very good correlation coefficients for their linearized equations. The maximum adsorption amounts of the hydrogels for the metal ions, based on the Langmuir model, were 182 and 200 mg/g for Cu(II) and Ni(II), respectively. When the initial concentration of metal ions was 1000 mg/g the actual adsorption amounts of the hydrogels for Cu(II) and Ni(II) were 181 and 183 mg/g, respectively.

Cellulose aerogels (CA) were widely used in the adsorption field due to high porosity, ultra-light quality, high-proportioned surface area. This article used a 3D La-CA-based adsorbent to improve wastewater eutrophication. Filter paper as cellulose source was applied and lanthanum was doped. Batch adsorption experiments showed that the maximum phosphate adsorption capacity could reach 54.377 mg g −1 (pH = 3.0). At the same time, the leaching of the lanthanum of the adsorbent was negligible, which proves good stability. In particular, the 3D La-CA presented an overall cylindrical monolith and would be easily separated from water compared with the powdery adsorbent. The adsorption performance of La-CA was not significantly affected by the competitive ions (F − , SO 4 2− , Cl − , NO 3 − ) and could still maintain 84.8% after 5 cycles. And mechanism analysis suggested that the 3D La-CA had a specific affinity with phosphates, through electrostatic attraction and inner-sphere complexation. In general, these 3D La-doped cellulose aerogels would provide new possibilities for the practical application of adsorbents in phosphate adsorption.

The hierarchical zeolite (ZC) was synthesized by using electrospinning cellulose microfibers (ECM) with three-dimensional network structure as a hard template. The textual and structural properties of the prepared materials were characterized by powder X-ray diffraction patterns (XRD), nitrogen adsorption–desorption analysis, scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, and TG-DSC. In terms of adsorption properties, the performance was examined by adsorption of methylene blue (MB) on the conventional zeolite (ZA) and ZC. The results showed that ECM templating could significantly increase the mesoporous area and volume of the traditional microporous zeolite, and thus improve the mass transfer performance and adsorption capacity. ZC exhibited much faster and higher MB removal performance than the traditional zeolite with adsorption rate constant and maximum adsorption capacity of ZC approximately 20 and 1.2 times greater than that of ZA. Besides, ZC exhibited better resistance to interfering ions than ZA. Moreover, ZC could be conveniently regenerated by washing with NaCl and the MB adsorption capacity was almost constant in five cycles of the regeneration. These features enable ZC to be an effective and promising adsorbent to remove MB from water.

Cellulose-based thermoplastic elastomers (TPEs) have attracted considerable attention because of their rigid backbone, good mechanical properties, renewable nature and abundance. In the present study, sustainable TPEs based on ethyl cellulose (EC), fatty acid and furfural were generated by the combination of ATRP and “click chemistry”. To fabricate sustainable TPEs with higher toughness, a range of polymers, including mono random-copolymer poly(tetrahydrofurfuryl methacrylate- co -lauryl methacrylate) (P(THFMA- co -LMA), dual polymer side chains PTHFMA and PLMA, and mono-block copolymer PTHFMA- b -PLMA, were designed as side chains to fabricate EC brush copolymers with random, dual or block side chain architectures using the “grafting from” and “grafting onto” methods. The multi-armed structures, chemical compositions and phase separation of these EC brush copolymers were confirmed by FT-IR, 1 H NMR, GPC, DSC, TEM and SEM. Overall, three types of EC brush copolymers all exhibited the desired mechanical properties of TPEs. In addition, the EC brush copolymers with dual/block side chain architectures showed higher tensile strength than that of the random polymers with similar compositions.

A rapid and efficient strategy for preparing amino cellulose nanofibers (A-CNFs) via click-like amino-yne functionalization was developed. Cellulose was initially swelled in a catalytic deep eutectic solvent (DES), followed by partial alkynylation with propiolic acid and amination with ε-poly- L -lysine. The optimization of reaction conditions resulted in a process that could be completed in just 7 h at 80 ° C. Antibacterial assays showed that 0.4 wt % A-CNF dispersion inhibited Escherichia coli and Staphylococcus aureus growth by 98.96% and 99.99%, respectively, with complete inhibition achieved at 0.6 wt %. When integrated with poly(vinyl alcohol) (PVA), the 1% A-CNF/5% PVA coating film displayed superior barrier properties, with water vapor and oxygen transmission rates of 160.5 g·m −2 ·day −1 and 5.462 × 10 −5 cm 3 ·m −2 ·day −1 ·Pa −1 , respectively. Practical application on cherry tomatoes’ preservation demonstrated a 35.7% delay in decay over 14 days at ambient temperature. This study offers an efficient and sustainable solution for active food packaging, highlighting the potential of A-CNFs in fruit preservation.

Thiol/MCMs-Ni microspheres synthesized via green aqueous epoxy-thiol grafting. • Microspheres are uniform 2 μm spheres with superparamagnetism, enabling rapid magnetic separation within 30 s. • Achieves high BSA adsorption capacity of 77.37 mg/g, fitting Langmuir isotherm and pseudo-second-order kinetics. • More than 91.5% elution efficiency and 67.56 mg/g capacity after five cycles, demonstrating excellent recyclability. In this study, cellulose was epoxy-functionalized with glycidyl methacrylate (GMA), and sodium hydrosulfide (NaHS) was further introduced to successfully prepare thiol-modified magnetic cellulose microspheres (Thiol/MCMs-Ni) for protein separation research. This green and scalable strategy addresses the pressing demand for efficient adsorbents in downstream bioprocessing, where rapid magnetic separation can circumvent conventional centrifugation and filtration bottlenecks, reducing operational complexity and cost. The material was systematically characterized by FTIR, XRD, SEM, VSM, and XPS. The results indicated that the Thiol/MCMs-Ni microspheres exhibited a regular spherical shape with a particle size of approximately 2 μm, while also demonstrating good magnetic responsiveness and thermal stability. Adsorption experiments using bovine serum albumin (BSA) as a model protein showed that the adsorption behavior conformed to the pseudo-second-order kinetic model and the Langmuir isotherm adsorption model, with a maximum adsorption capacity of 77.37 mg/g. Thermodynamic analysis indicates that the adsorption is a spontaneous and endothermic process, and the material still maintains a high elution efficiency of more than 91.5% after five cycles of use. This study provides a novel approach for developing efficient and green materials for protein separation. Download: Download high-res image (140KB) Download: Download full-size image

Global freshwater scarcity has intensified interest in passive fog harvesting as a low-energy strategy for decentralized water supply. However, most existing fog-harvesting systems rely on complex structures or extreme wettability gradients, making it difficult to simultaneously optimize droplet capture, growth, and removal. Herein, a synergistic strategy combining wettability regulation and flow-guiding structures is proposed for efficient fog harvesting. Electrospun cellulose acetate nanofibrous membranes were subjected to controllable alkaline deacetylation to regulate surface wettability. Appropriate hydrophilicity promoted droplet nucleation, adhesion, and sustained growth. The membrane treated for 2 h (DCA2 NFM) exhibited balanced wettability and increased the fog collection rate from 1.481 to 2.519 g·cm −2 ·h −1 . Furthermore, parallel copper wire arrays were introduced to construct low-resistance drainage pathways, accelerating gravity-driven droplet transport and surface renewal. As a result, the optimized membrane achieved a fog collection rate of 3.996 g·cm −2 ·h −1 . This work provides a simple and scalable strategy for coordinating droplet capture and drainage in passive fog harvesting.

Rice-straw-derived CNF/lignin aerogels were developed as microwave-passive insulating cores. • CNF/L10 provided the best balance of porosity, strength, moisture tolerance, and insulation. • Low thermal conductivity and humid-state dielectric loss supported reduced wall self-heating. • CNF/L10 prototype walls reduced outer sidewall temperature from 62.7 to 45.9 °C. • CNF/L10 retained mechanical stability and microwave transmittance after 1000 wash–reheat cycles. Rice-straw-derived cellulose nanofiber/lignin (CNF/lignin) aerogels were developed as microwave-passive insulating cores for reusable food-container walls. Cellulose and lignin co-recovered from Vietnamese rice straw were reassembled into aerogels containing 0–20 wt% lignin to define a practical formulation window for microwave-reheatable packaging. Moderate lignin addition preserved the cellulose I framework and improved the balance between pore-wall integrity, moisture tolerance, thermal insulation, and dielectric stability. Among the tested samples, CNF/L10 gave the best overall performance, with a density of 0.025 ± 0.001 g cm −3 , porosity of 98.33 ± 0.07%, compressive modulus of 74.6 ± 3.7 kPa, compressive strength of 32.7 ± 1.8 kPa at 70% strain, water contact angle of 79.2 ± 2.8°, and moisture absorption of 49.8% after 48 h at 75% RH. Its thermal conductivity remained low, increasing only from 0.0288 ± 0.0009 W m − 1 K − 1 at 50% RH to 0.0336 ± 0.0011 W m − 1 K − 1 at 75% RH. At 2.45 GHz, CNF/L10 showed ε′ = 1.61, ε″ = 0.053, and tanδ = 0.0329 at 50% RH, and ε′ = 1.93, ε″ = 0.129, and tanδ = 0.0668 at 75% RH. In a PP/aerogel/PP prototype wall, CNF/L10 reduced the outer sidewall temperature from 62.7 ± 1.2 °C to 45.9 ± 0.9 °C while maintaining food-center heating. After 1000 wash–reheat cycles, it retained 86.8% modulus, 85.0% strength, and 87.8 ± 1.5% microwave transmittance, with overall migration below 10 mg dm −2 . These results support CNF/L10 as a promising bio-based insulating core for lower-plastic microwave food-packaging prototypes.

Foams have found widespread application in a variety of industries, owing to their distinctive characteristics. In the field of oil development, the injection of foam into the formation is a common method to enhance oil recovery. However, when traditional foam systems encounter the oil phase, the spreading of the oil phase on the liquid film leads to a significant decrease in their stability, which adversely affects their application. In this study, two surfactants, sodium dodecyl sulfate and lauramidopropyl hydroxy sulfobetaine, were selected and compounded at a mass ratio of 2:1 to construct a foam system with optimal foamability and foam stability. At 0.3 wt%, the foam volume reached 820 mL, and the liquid drainage half-life was 6.73 min. After adding 0.02 wt% bacterial cellulose, the foam volume of the system only decreased by 30 mL, but the half-life increased by 8.2 min. The results of single-bubble oil resistance experiments and microscopic model experiments both demonstrated that the ternary composite foam system exhibited effective oil resistance. Through emulsification experiments combined with the measurement of interfacial tension and interfacial dilatation modulus, it was found that the excellent oil resistance of the ternary composite foam system was due to the low oil-water interfacial tension and high interfacial dilatation modulus.
