Outdoor facilities such as charging infrastructure and box-type transformers face simultaneous threats from icing in cold environments and fire hazards during service, creating a strong demand for multifunctional protective coatings. This study proposes a hierarchical coating design that synergistically combines a flame-retardant matrix with a photothermal superhydrophobic surface to achieve integrated anti-icing/de-icing and fire-safety functions. To realize this concept, dopamine-modified TiO₂ and flame-retardant modified cellulose were used to construct the coating matrix, while multi-walled carbon nanotubes and fumed silica were deposited on the surface to create a micro/nanostructured hydrophobic layer with enhanced light-to-heat conversion capability. This architecture enabled the composite coating to achieve a water contact angle of ∼147°, an icing delay time of 1902 s, and a maximum surface temperature of 71.8 °C under one-sun irradiation, demonstrating effective photothermal de-icing capability. Additionally, it exhibited ultrafast fire-alarm response (<3.5 s), stable alarm cycling behavior, and excellent flame retardancy, together with robust durability under extreme temperatures, water-flow erosion, and mechanical abrasion. Overall, this study demonstrates a cost-effective and scalable strategy for integrating flame retardancy, rapid fire warning, and efficient anti-/de-icing capabilities within a single coating system, offering considerable potential for protecting outdoor equipment in harsh environments.

The pervasive contamination of micro/nanoplastics (MNPs) has emerged as a growing threat to global ecosystems and human health. In this study, a sustainable remediation strategy was proposed using polydopamine (PDA)-modified bacterial cellulose (BC) nanofibrous spheroids (PDA-BC) for the efficient sequestration of MNPs from aqueous environments. The PDA-BC spheroids demonstrated robust capture performance over a wide particle-size range, as well as across varying temperatures, pH values, and salinities, achieving an adsorption capacity of 461.62 ± 61.43 mg/g for 100 nm polyethylene terephthalate (PET) MNPs. Effective removal was also demonstrated for multiple polymer types, including polystyrene (PS), polypropylene (PP), and polyethylene (PE), with maintained its efficacy in real-world water matrices. Mechanistic analyses revealed that the superior performance was attributed to the synergistic contributions of physical interception and interfacial interactions, including electrostatic interactions, hydrogen bonding, and van der Waals forces. Beyond remediation, the discarded MNPs-loaded PDA-BC adsorbents were upcycled into mechanically reinforced composite films via citric acid-mediated hot-pressing, resulting in a 42.06% increase in tensile strength. This work not only enabled effective MNPs sequestration but also transformed waste into value-added products, offering a closed-loop route solution for MNPs pollution mitigation.

Sustainable alternatives with enhanced performance have attracted a great deal of research attention in response to the growing environmental and energy problems posed by petroleum-based plastics. However, the mechanical strength, water resistance, and functional properties of conventional bioplastics are occasionally restricted, limiting their utility. In this work, we describe a versatile cellulose-based bioplastic created through combining citric acid as a cross-linker and Ketjen black as a conductive filler with a carboxymethyl cellulose matrix. The optimized composite exhibits outstanding mechanical properties, including a tensile strength of 51.31 MPa and an elongation at break of 50.24%, as well as considerable electrical conductivity of 76.15 S/m, and a notable electromagnetic interference shielding effectiveness of 22.71 dB at a thickness of 0.19 mm. Its environmental compatibility was validated through soil degradation tests, confirming 100% biodegradability within 100 days with no observed effects on plant development. This study offers significant potential for flexible electronics and sustainable packaging by providing an environmentally friendly and scalable technique for designing high-performance multifunctional bioplastics.

Structurally colored photonic pigments are widely used in decorating, paints, and security packaging due to their unique iridescent colors and nontoxicity. However, the poor solvent stability and single optical property of the photonic pigments hinder their applications in the fields of multilevel anticounterfeiting and information encryption. Herein, by integration of cellulose nanocrystals (CNCs) with fluorescent carbon dots, solid CNC films with both fluorescent and structural colors are successfully fabricated via a self-assembly strategy. Ultrasonic treatment is employed to modulate the structural color of CNC films across the visible spectrum. After that, CNC-based photonic pigments are produced by heat and pulverization treatment, displaying excellent solvent stability and good color responsiveness. Importantly, the CNC-based photonic pigments display structural color and fluorescence stability under a wide range of temperatures (−65–70 °C) and photoirradiation. In addition, polymers are used to encapsulate CNC-based chiral photonic pigments to produce photonic plastics and coatings with fluorescent and structural colors, which can be applied in multidimensional anticounterfeiting and photonic coatings. This strategy provides a pathway for the functionalization of biomass photonic pigments.

Sustainable crop protection relies on the development of pesticide formulations characterized by intelligent release performance and high biological safety. However, due to the reliance on costly functional additives and complex synthesis processes, achieving all these multiple functions simultaneously still poses a formidable challenge. Here, we report cost-effective methacrylic anhydride-functionalized cellulose nanocrystals (MCNCs)-stabilized high internal phase Pickering emulsion (IMI@MCNCs-HIPPE) as a template for constructing a smart insecticide system. Through in situ radical polymerization of N, N-Diethyl-2-propenamide (DEAAM), we synthesized IMI@MCNCs-g-DEAAM microcapsules that exhibit multi-stimuli responsiveness (dual-pH responsive and temperature responsive), efficient pesticide encapsulation (96.5%), and a high loading capacity (58.2%). The resultant microcapsules demonstrate sustained and controlled release along with exceptional spreading, adhesion, rainfastness, and photostability on corn and tomato leaves, outperforming the commercial EC (Bisair®). Bioassays against Rhopalosiphum maidis and Tomato leafminers confirmed superior insecticidal efficacy of the microcapsules, while safety assessments on seed germination, soil microbes, and zebrafish indicated excellent environmental compatibility. This research innovatively establishes a sustainable, cost-effective, and multifunctional nanocellulose-based platform, enabling controlled release, precise targeting, and improvement in biological safety, thereby providing critical technical support for sustainable agriculture.

Tunable compact lasers hold great promise as integrated light sources for sensing, display and lab-on-a-chip applications, yet most existing devices rely on complex manufacturing process or synthetic materials that conflict with environmental sustainability requirements. Here, we construct a green cholesteric liquid crystal host using plant-derived hydroxypropyl cellulose doped with an organic laser dye. The high viscous material has disordered helical structure with thermo-responsive property, enabling the switching between random laser and band-edge-enhanced random laser by regulating the photonic bandgap position relative to the gain band via temperature control. The coupling between the high-density band-edge state with the multiple scattering network results in tunable emission wavelength, lower lasing threshold, extended feedback path, multimode coexistence and circular polarization property. This work helps to elucidate the light-matter interaction in complex biobased photonic structures and showcases the possibility for sustainable optical devices.

The development of sustainable and economical active food packaging remains a critical challenge for enhancing food quality and safety. This study presents an innovative strategy by utilising rice bran, an abundant agricultural waste product, to synthesise rice bran–derived bacterial cellulose (RBC) as a high-value matrix for active food packaging. This matrix was reinforced with zeolitic imidazolate framework-8 (ZIF-8) to fabricate multifunctional nanocomposite films. Structural analyses confirmed the successful integration of ZIF-8 into the RBC matrix via hydrogen bonding without disrupting its inherent crystalline lattice. The incorporation of ZIF-8 significantly improved the physical and functional characteristics of the packaging. Specifically, the optimal formulation (0.2% ZIF-8) enhanced tensile strength to 42.72 MPa and improved barrier properties against water vapour and oxygen. Notably, the film loaded with 0.1% ZIF-8 exhibited remarkable antibacterial efficacy, achieving a 99.41% inhibition rate against Escherichia coli . During chilled pork preservation trials, the nanocomposite films effectively suppressed microbial proliferation, delayed lipid oxidation and minimised the accumulation of volatile spoilage compounds. These synergistic effects successfully extended the shelf life of the pork by 6 days, demonstrating the film's superior capacity to extend food shelf life and ensure microbiological safety. This work highlights the promising potential of valorising RBC as a sustainable and highly efficient platform for advanced active food packaging.

In this study, cyanoethyl cellulose (CEC) was used as a membrane material, and polyvinylpyrrolidone (PVP) was used as pore-forming agent to prepare the substrates for the thin-film composite (TFC) forward osmosis (FO) membrane for the first time. The experimental results demonstrate that the properties of the substrates were significantly improved after PVP was added. The scanning electron microscope (SEM) images show that a two-sublayer structure, a fringe-like top sublayer and macrovoids with sponge-like wall bottom sublayer, were formed after the addition of PVP. These improvements contributed to improved membrane performance during FO tests. Meanwhile, after adding PVP, the TFC membranes exhibited good water flux, and excellent specific reverse salt flux. For instance, the TFC-M2 exhibited 9.10/20.67 LMH water flux, 1.35/2.24 gMH reverse salt flux, and 0.15/0.11 g/L specific reverse salt flux in FO/pressure-retarded osmosis mode while using 1 M NaCl as the draw solution and deionized (DI) water as the feed solution.

Conventional low-density polyethylene (LDPE) mulch films have caused serious white pollution, driving the need for sustainable alternatives. Biodegradable cellulose paper mulch has shown great potential, yet its practical use remains limited by excessive water absorption and poor mechanical strength. To overcome these drawbacks, a sandwich-like multilayer structure was innovatively constructed by successively coating cationic starch (S) and 3-aminopropyl triethoxysilane (APTES) onto cellulose substrates, followed by glyoxal-mediated cross-linking (CSGA). CS acted as an interfacial adhesive via hydrogen bonding and electrostatic interaction, while APTES introduced hydrophobic silane moieties through Schiff base and acetal linkages. Compared to pristine cellulose paper, the resultant composite film (CS 3 GA 5 ) exhibited a significant improvement in dry tensile strength (26.8 MPa) and wet tensile strength (5.2 MPa), with a water contact angle increased from 16° to 128°, and a reduced swelling ratio from 123 % to 62 %. Additionally, the seed germination rate under CS 3 GA 5 was 82 %, comparable to that of commercial LDPE mulch. The CS 3 GA 5 film also demonstrated complete biodegradability within 56 days in natural soil, aligning with crop growth cycles. This work presents a facile and scalable approach for fabricating high-performance biodegradable mulch films, offering a promising solution for microplastics pollution.

Environmentally benign and biodegradable chitosan (CS) membranes have disadvantages such as low mechanical strength, high brittleness, poor heat resistance and poor water resistance, which limit their applications. In this paper, home-made cellulose nanocrystals (CNC) were added to CS to prepare CNC/CS composite membranes through mechanical mixing and solution casting approaches. The effects of CNC dispersion patterns and CNC contents on the properties of composite membranes were studied. The analysis of the surface and cross-section morphology of the membranes showed that the dispersion performance of the composite membrane was better in the case that CNC was dissolved in an acetic acid solution and then mixed with chitosan by a homogenizer (Method 2). CNC had a great length-diameter ratio and CNC intensely interacted with CS. The mechanical properties of the composite membrane prepared with Method 2 were better. With a CNC content of 3%, the tensile strength of the composite membrane reached 43.0 MPa, 13.2% higher than that of the CNC-free membrane. The elongation at break was 41.6%, 56.4% higher than that of the CNC-free membrane. Thermogravimetric, contact angle and swelling analysis results showed that the addition of CNC could improve the heat and water resistance of the chitosan membrane.

Maximizing the use of waste is an important part of the strategy for sustainable development. Lignosulfonate , a waste product with sufficient reactive functional groups, can be used as reinforcing materials in polymer composites . In this work, composite hydrogels composed of lignosulfonate- graft -poly (acrylic acid) AA network and hydroxyethyl cellulose (HEC) polymer chains are synthesized through in situ polymerization and cross-linking reaction. The composite hydrogels have semi-interpenetrating network (semi-IPNs) structure, which is driven by the hydrogen bond interactions between proton-donating PAA and proton-accepting HEC. The mechanical properties of these composite hydrogels, including fracture stress, critical compression and elastic modulus and elongation are investigated by tensile measurements. These composite hydrogels exhibit higher toughness and extensibility compared to conventional PAA polymer hydrogels. Moreover, full recovery of their original shape after the removal of compression stress indicates their excellent shape-recovery property. Due to their porous structure , these hydrogels show stimuli responsive swelling properties in aqueous solution depending on the pH or ionic strength , which facilitate the repeating absorption and removal of dyes. Therefore, this work may open a new pathway to synthesize functional materials based on lignosulfonate.

This study investigated the structural and performance characteristics of cellulose nanofibers (CNFs) prepared through Fe 2+ assisted cold plasma (CP) pretreatment of cellulose. The results indicated that the high-energy active particles generated by Fe 2+ assisted CP played a crucial role in the deconstruction of cellulose, resulting in CNFs with a more uniformly dispersed network structure, increased carboxyl content, and enhanced intramolecular hydrogen bonding. This effect was particularly pronounced at a working voltage of 60 kV. In addition, the mechanical properties of CNF films exhibited significant improvements in tensile strength and elongation at break. At a working voltage of 60 kV, the tensile strength and elongation at break of the CNF film increased by 21.79% and 78.91%, respectively, compared to that obtained without pretreatment. Compared to enzymatic pretreatment methods, the Fe 2+ assisted CP pretreatment offered distinct advantages in both time efficiency and mechanical performance enhancement of CNF film. Considering the overall structure and properties of the CNFs, a working voltage of 60 kV was determined to be optimal for Fe 2+ assisted CP pretreatment, yielding superior CNF performance.
