Transparent polymer films are widely used in optical devices, packaging, and information display, but most of them are derived from non-renewable petrochemical resources and show limited environmental sustainability. Cellulose represents an attractive natural polymer alternative owing to its high abundance and biodegradability. However, its pronounced hydrophilicity and limited functional integration restrict the development of advanced transparent cellulose-based films. In this work, highly transparent, water-resistant, and fluorescent cellulose-based films were fabricated from bleached forestry pulp through sequential carboxymethylation, periodate oxidation, silane coupling, diamine-assisted crosslinking, and post-functional fluorophore grafting. Carboxymethylation enabled the formation of transparent films, while silane modification and network construction significantly improved the surface hydrophobicity and water durability of the cellulose matrix. Subsequent immobilization of N-(1-pyrene)maleimide endowed the films with distinct fluorescence. The resulting films maintained high optical transparency after multistep functionalization, with a transmittance of about 90% in the visible region, exhibited a water contact angle of 101.6°, and a tensile strength of about 70 MPa. In addition, the fluorescent films showed clear optical responses under UV irradiation. This work provides an effective strategy for constructing a transparent cellulose-based platform that simultaneously integrates hydrophobicity, fluorescence functionality, and mechanical reinforcement through sequential covalent modification, and highlights their potential in optical labeling, smart packaging, flexible substrates, and security marking.

Passive radiative cooling offers a sustainable pathway for thermal management by minimizing solar absorption while maximizing mid-infrared (MIR) emission through the atmospheric transparency window. However, parasitic heat gain substantially compromises its net cooling efficiency. Here, we report a reversible xanthation-mediated strategy to fabricate hierarchical SiO 2 @cellulose nanofiber aerogels that synergistically integrate broadband solar reflectivity, high MIR emissivity, and low thermal conductivity. The xanthation chemistry enables uniform, in situ anchoring of ∼300 nm SiO 2 nanospheres along nanofibers, creating a distinctive ‘pearl-necklace’ morphology, while directional ice-templating further constructs lamellar hierarchical porous networks that suppress nonradiative heat transfer. The optimized aerogel exhibits an average solar reflectance of 95.6%, a MIR emissivity of 95.3% within the 8–13 µm atmospheric window, and an ultralow thermal conductivity of 0.028 W m −1 K −1 . Under 1000 W m −2 solar irradiance, it achieves a time-averaged subambient cooling of 3.7°C and a net temperature reduction of 24.9°C compared to polystyrene foam, while extending refrigeration thermal cycling by 47.3%. This work provides a scalable material design framework for monolithic integration of optical selectivity and thermal insulation, offering a promising sustainable solution for energy-efficient buildings, cold-chain logistics, and next-generation thermal management systems.

Temperature-responsive hydrogels are ideal intelligent carriers for drug delivery due to their ability to enable precise and on-demand drug release. Compared to synthetic polymers with similar thermoresponsive properties, hydroxypropyl cellulose (HPC) offers distinct advantages for drug delivery applications due to its wider availability from natural sources, lower cost, and superior biocompatibility and biodegradability. However, the lower critical solution temperature (LCST) is relatively high (40–50 °C), and it cannot form a cross-linked network by itself, which limits its practical application in drug delivery. Herein, we innovatively developed an injectable, thermoresponsive, drug-loaded hydrogel microsphere (HPC-AGE/PVA@DS). This system achieves on-demand drug release via thermoresponsive hydrogel shrinkage at a physiological temperature (37 °C). Poly(vinyl alcohol) (PVA) effectively prevents microsphere fracture during shrinkage, thereby avoiding burst drug release. The microspheres also exhibit excellent lubricity, along with outstanding biocompatibility and superior anti-inflammatory efficacy compared to nonthermosensitive hydrogels. This stimuli-responsive localized drug delivery system offers a promising platform for treating osteoarthritis (OA) and other chronic diseases.

Achieving durable lubrication and effective damping, which are essential for suppressing friction-induced vibration and noise, remains a challenge in water-lubricated polymer friction components. In this study, a slippery multi-crosslinked polyvinyl alcohol (PVA) hydrogel (MCPH) was proposed based on PVA as the hydrogel matrix, carboxylated cellulose nanofibers as reinforcing agents, and various reversible interactions as efficient energy dissipation mechanisms. Subsequently, the prepared MCPH was blended with thermoplastic polyurethane (TPU), and a novel TPU/MCPH composite was developed. Friction and vibration experiments demonstrated that the incorporation of MCPH significantly enhanced the aqueous lubrication of the TPU composite, which was attributable to the synergistic effects of the improved hydrophilicity, water absorption/release functions of MCPH, and hydration lubrication. Moreover, the reversible interactions within MCPH were continuously disrupted and rapidly reconstructed under frictional shear stress, enabling efficient mechanical energy dissipation and enhancing the damping capacity of the TPU/MCPH composite. Consequently, under the synergistic effects of improved lubrication and enhanced damping capacity, the modified TPU composite exhibited a low coefficient of friction of 0.109 under aqueous conditions and a substantial reduction in vibration and noise responses. This innovative composite provides a promising strategy for developing high-performance polymer friction materials with superior lubricity and vibration-noise suppression under aqueous environments.

Developing organic room-temperature phosphorescence (RTP) materials stable in aqueous environments remains highly challenging due to the facile quenching of triplet excitons. Inspired by the protective β-barrel architecture of the green fluorescent protein ( Aequorea victoria ), the study presented a covalent anchoring strategy based on an amphiphilic cellulose derivative (cellulose acetate) to construct water-resistant and scalable RTP materials. Covalent immobilization of chromophores within the rigid framework yields dynamic photoactivated afterglow, extending the lifetime from 2.1 to 946.4 ms. The resulting films retain bright RTP even under water while exhibiting water-mediated tunable mechanical properties. Furthermore, Förster resonance energy transfer with Rhodamine B enables full-color RTP spanning blue to orange. Benefiting from the inherent thermoplasticity and hydroplasticity of cellulose acetate, the RTP cellulose derivatives are readily processed into diverse 1D/2D/3D architectures and applied in multilevel information encryption. This covalent anchoring strategy offers a sustainable and commercially viable pathway to robust polysaccharide-based RTP, opening new opportunities for optoelectronics, security, and eco-friendly photonic technologies.

Solid-state electrolytes (SSEs) offer a promising pathway for replacing flammable liquid electrolytes in lithium metal batteries. However, their widespread application remains limited by low ionic conductivity, interfacial incompatibility, and high production costs. Here we introduce a cellulose-based SSE featuring sulfonyl-functionalized polymer chains that simultaneously enhance ionic transport and interfacial adhesion. The rich microdomain gradient-concentration sulfonated cellulose (RMGC-SC) achieves optimal ionic conductivity (1.11 × 10 −3 S cm −1 ) and intimate interface contact, and supports 1000 h of uninterrupted plating/stripping in Li||Li symmetric cells at 0.2 mA cm −2 (0.2 mAh cm −2 ). Moreover, Li||LiFePO 4 coin cells deliver outstanding cycling performance with a minimal capacity fade of only 0.023% per cycle, and a 5 × 5 cm 2 pouch cell with an areal loading of 11.2 mg cm −2 still retains 94.9% of its initial capacity, highlighting the electrolyte's practical robustness. Furthermore, a non-solvent-induced phase separation strategy enables efficient recovery and reuse of the cellulose matrix and lithium salt, establishing a closed-loop recycling approach that reduces costs and environmental impact. This work demonstrates the potential of polymer molecular functionalization in precisely tuning SSE properties, offering a sustainable and scalable pathway toward high-performance solid-state battery technologies.

Microbial contamination leading to food spoilage necessitates the development of food packaging films with both monitoring and sterilization functions. In this study, we developed a dual-functional film named Anthocyanin/Alizarin-hypocrellin B (ATH/ALI-HB) that simultaneously integrates freshness monitoring, sterilization, and data-driven freshness evaluation within a single platform. By integrating bacterial cellulose with polysaccharides, the ATH/ALI-HB film substrate effectively overcomes the intrinsic brittleness of pure bacterial cellulose films. Incorporating various pigments, the film exhibits sensitive pH-dependent color changes for freshness monitoring. Specifically, the ATH/ALI-HB film's change from brown to purple signals the onset of the spoilage process, and it successfully delays meat spoilage until day 10. Photosensitizers incorporated into the film improve sterilization efficiency, as demonstrated by the ATH/ALI-HB film's ability to reduce Listeria monocytogenes populations from 10 6 CFU/mL within 15 min due to the production of reactive oxygen species (ROS). Additionally, a one-dimensional convolutional neural network (1D-CNN) model based on Raman spectrum was proposed to make a more precise judgment of the freshness of meat, enabling fully accurate (100%) classification of meat freshness states. This work presents a novel strategy for intelligent food packaging, in which material design, monitoring, sterilization, and artificial intelligence–assisted sensing are seamlessly integrated, paving the way for future advancements in food packaging technology.

Cellulose-based hydrogels, owing to their softness, biocompatibility, and ionic conductivity, hold promise for applications in wearable sensing and human–machine interfaces. Herein, we present an effective strategy for synthesizing the PAAP-CMCs-PA hydrogel by incorporating carboxymethyl cellulose (CMC) and phytic acid (PA), with an optimized balance between mechanical and conductive properties. Strong electrostatic interactions and multiple hydrogen bonds are established within the polymer network, thereby reinforcing structural stability and endowing the hydrogel with excellent integrated properties. As a result, the PAAP-CMCs-0.2 PA hydrogel exhibits high ionic conductivity (7.8 S/m), considerable tensile strength (0.68 MPa), substantial stretchability (1473%), and robust adhesion (10.38 kPa) on diverse substrates. In addition, the hydrogel demonstrates remarkable antifreezing performance at low temperatures and reasonable antibacterial activity. These multifunctional properties endow the hydrogel with stable signal-detection capability for subtle motions, thereby enabling Morse code information transmission, indicating an effective design strategy for flexible sensors in harsh cold conditions.

Developing redispersible nanocellulose products is crucial for their industrial applications. However, challenges persist in developing convenient and efficient processes. This study presents a green strategy using dynamic covalent chemistry to tune the hydrogen-bonding network of cellulose nanocrystals (CNCs). CNCs were combined with sodium lipoate (SL) in an aqueous solution and dried to form composite films. SL incorporation effectively prevents CNC aggregation via electrostatic repulsion and steric hindrance, transforming the CNC skeleton structure from a “bundle-to-bundle” structure to a uniform, horizontally stacked architecture. The composite films exhibited enhanced transparency, surface smoothness, and tunable mechanical properties. Upon water immersion, SL depolymerized and separated with 100% recovery. The remaining CNC skeleton readily redispersed into individual nanocrystals via sonication, achieving near-complete recovery even with 15% SL. This simple, water-based process tailors CNC film performance and enables complete closed-loop recycling, offering sustainability and simplicity for advanced applications.

Cellulose-based fabrics are ubiquitous in daily life due to their processability, biodegradability, and flexibility. Integrating cellulose-based fabrics with functional coatings can release their potential functions to participate in various applications. However, the large-scale production of multifunctional fabrics still remains a great challenge. Herein, a multifunctional superhydrophobic hemp fabric (HF) with integrated antibacterial, fluorescent, UV-blocking, self-cleaning, and oil-water separation capabilities was fabricated via an effective interfacial engineering strategy based on diazonium chemistry and MOF assembly. The HF surface was grafted with a polymer layer of benzoic acid via diazonium chemistry, which provided abundant active sites of carboxy group to effectively anchor Ce-MOF. A dense hierarchical morphology was constructed on HF by in-situ growth of Ce-MOF, and a large number of pores were generated by self-assembly, which could be used to load berberine (Ber) and then modified with stearic acid to prepare superhydrophobic fabric. The water contact angle of the modified HF is as high as 154°, and it has good self-cleaning performance. The oil-water separation efficiency of the modified fabric is remarkable (97%), and it can effectively separate light and heavy oil from water. The modified fabric exhibits excellent UV-blocking performance with a high UPF of 70.2. Encouragingly, Ber also endows HF with excellent antibacterial and fluorescence properties. Encouragingly, the tensile strength of HF was not significantly affected. This study not only focuses on the materials design and large-scale fabrication but also provides multifunctional hemp fabrics with broad application prospects for many fields.

Simultaneously improving the functional durability and ecological sustainability of textile dyeing and finishing techniques has long presented a formidable challenge in textile processing. This study utilized a surface-dissolution strategy to functionalize polyethylene terephthalate (PET) yarns with cinnamate-functionalized cellulose nanocrystals (CinCNC), imparting durable ultraviolet (UV)-blocking properties. Incorporating CinCNC stabilized the yarn, reducing the coefficient of variation (CV) for yarn breaking strength to 6.43%, significantly enhancing its stability. The resultant woven fabric exhibited excellent UV-blocking performance, wash fastness, air permeability, and antistatic properties. The fabric achieved a maximum ultraviolet protection factor (UPF) of 273.54, retaining a UPF of 203.20 after 10 laundering cycles. Compared to conventionally coated fabrics, this method improved fabric air permeability by 22.60%. Furthermore, the static dissipation rate of fabrics processed via this technique increased by 46.70% compared with the untreated counterparts. The yarns and fabrics produced using this approach demonstrated outstanding overall properties, further underscoring the advantages of functional nanocellulose in developing advanced textiles. This technique holds significant potential for superseding conventional coating methods and may find application in producing outdoor tents and umbrellas.

In aquatic environments, traditional cellulose-based hydrogels face structure change challenges due to excessive swelling caused by hydrophilic groups, resulting in poor conductivity and limiting their electrochemical applications. To overcome these challenges, this study presents a bioinspired carboxymethyl cellulose/polyacrylamide/butyl acrylate/polyaniline (CMC/PAM/BA/PANI) composite hydrogel, mimicking the smart responsive interface of hydrophobic human skin. When applied in the electrochemical capture of nanoplastic in wastewater, the flexible CMC/PAM network resembles the subcutaneous layer as the substrate, the BA's hydrophobic long-chain esters allow for selective nanoplastic interaction, while the PANI component at the outmost surface enables conductive charge transfer for precise adsorption control, achieving a superior 96% removal efficiency for polystyrene nanoplastic (1 mg/L) at 1 V with good reusability. This biomimetic design synergistically combines electrostatic adsorption, hydrophobic interactions, and π-π stacking interactions. Mechanism studies reveal pseudo-second-order kinetics with Freundlich-dominated adsorption. The biomimetic design, inspired by skin's layered structure and functionality, achieves intelligent and efficient nanoplastic removal through precisely engineered interfacial interactions, offering new perspectives for advanced water purification technologies.
