Petroleum-based plastic packaging stays in the environment longer and raises safety concerns, prompting the development of sustainable bio‑based alternatives. Herein, high‑performance regenerated cellulose (RC) films reinforced with phenolated lignin nanoparticles (P‑LNPs) were developed by dissolving softwood pulp in an ZnCl 2 /AlCl 3 inorganic molten salt hydrate system and regenerating it in water. Phenolation increased lignin’s phenolic–OH content, and nanolization allowed for uniform nanoparticle dispersion and strong interfacial interactions within the cellulose matrix. At 3 wt% P‑LNPs (RCPL‑3), the composite film showed a balanced profile: tensile strength of 89.14 MPa; elongation at break of 9.47%; water vapor permeability of 0.91 × 10⁻¹ ² g·cm/(cm²·s·Pa); visible‑light transmittance of 83.78%; UV blocking over 90%; and a water contact angle of 103.2°. The films possess antioxidant activity and inhibit the growth of Escherichia coli and Staphylococcus aureus . In a model application, RCPL-3 effectively slowed banana peel browning and reduced 7-day weight loss to 18%. Soil burial tests confirmed biodegradability with 71% mass loss after 60 days. These findings show that P-LNPs work together with regenerated cellulose to produce transparent, barrier-improved, antioxidant, and antibacterial films suitable for active, biodegradable food packaging.

Cellulose beads are produced through dissolution–regeneration processes that are solvent- and water-intensive and disrupt the native microfibrillar organization by converting cellulose I to cellulose II. Here, we establish a dissolution-free chemomechanical pathway that converts lignocellulosic biomass into spherical cellulose assemblies via architecture-governed cell-wall remodeling and shear-driven consolidation. Six feedstocks spanning agricultural residues (date palm, rice straw, corn straw, soybean straw) and woody biomasses (pine and peach wood) were subjected to sequential alkaline extraction, oxidative bleaching, and high-shear agitation. Comparative compositional, structural, and morphological analyses reveal that successful spheronization does not depend solely on cellulose content but requires the formation of a deformable continuity-preserving fibrillar intermediate. In this state, partial matrix removal induces wall swelling and delamination while maintaining load-bearing connectors that enable fibrillar bending, entanglement, and densification under hydrodynamic shear. Date palm and rice straw satisfy these criteria and produce stable cellulose I beads with fiber-assembled interiors. In contrast, corn and soybean residues undergo excessive fragmentation into fines that disperse as pulps/flocs, whereas pine and peach wood retain stratified, locked wall domains and yield irregular, rigid fragments. These findings establish an architecture-based mechanistic framework and selection rules for solvent-minimal, dissolution-free manufacturing of cellulose beads directly from low-value lignocellulosic biomass.

Co-pyrolysis of biomass and plastic enables simultaneous production of biochar, bio-oil, and gaseous products and also offers a pathway for waste recycling and valorization. This research investigates the synergistic effects of co-pyrolysis of cellulose and low-density polyethylene (LDPE) by TG-FTIR and a fixed bed reactor. Kinetic analyses by Flynn-Wall-Ozawa (FWO) and Kissinger-Akahira-Sunose (KAS) models showed that the average activation energy ( E a ) for pyrolysis of cellulose and LDPE individually was 184.1 and 267.4 kJ/mol, respectively, whereas that of 1:1 cellulose/LDPE mixture decreased to 150.4 kJ/mol. Pyrolysis experiment showed that co-pyrolysis suppressed biochar formation while enhancing yields of bio-oil and gaseous products. Co-pyrolysis enriched carbon and removed oxygen in biochar, resulting in maximum graphitization degree and higher heating value (HHV) of 31.51 MJ/kg at 700 °C. Additionally, co-pyrolysis decreased the relative content of light oxygenated compounds in bio-oil. The inhibitory effect of co-pyrolysis on aldehydes, ketones, and acids was maximum at 600 °C. Co-pyrolysis enhanced CH 4 and H 2 formation and suppressed CO 2 and CO. At 700 °C, CH 4 and H 2 proportions peaked to 19.3 vol% and 13.1 vol%, respectively, during co-pyrolysis. This research provides fundamental insights into the synergistic mechanisms of biomass and plastic co-pyrolysis for polygeneration.

Abstract Fatty acid cellulose esters (FACEs) are cellulose thermoplastics with wide application potential. However, the molecular factors governing the thermoplasticity of highly substituted FACEs remain poorly understood. Here, we synthesized a series of FACEs with varied side-chain lengths to clarify the role of intermolecular interactions. Characterization and density functional theory calculations showed that extensive esterification largely disrupted the hydrogen-bonding network, leaving van der Waals interactions (VDW) as the predominant intermolecular interactions. As the side-chain carbon numbers increased from 2 to 8, the Hamaker constant (Apoly/poly) decreased from 9.20 × 10−20 J to 6.04 × 10−20 J, accompanied by decreases in the melt flow temperature (Tf) from >240 °C to 120 °C and glass transition temperature (Tg) from 195 °C to 90 °C. Moreover, strong linear correlations (R2 ≥ 0.91) were established between Apoly/poly and Tg, Tf, providing a quantitative VDW-based framework for understanding the thermoplasticity of highly substituted FACEs.

Abstract Emerging as innovative multifunctional devices, antenna sensors integrate wireless communication and environmental sensing capabilities into a single architecture. Undoubtedly, it is advantageous for the development of green electronic materials to incorporate natural biomacromolecules into antenna sensors. Herein, a facile vacuum filtration process was reported for fabricating TEMPO-mediated oxidized cellulose paper (TOCP). Subsequently, highly porous Cu-1,3,5-benzenetricarboxylic acid (CuBTC) crystals were in situ introduced onto the surface of oxidized cellulose fibers via a layer-by-layer (LbL) growth technique. The TOCP/2CuBTC composite film with two growth layers exhibited a humidity-induced linear dielectric response. Moreover, simulations were performed for the antenna sensor based on the TOCP/2CuBTC film whose resonant frequency demonstrated a one-to-one correspondence with humidity levels, achieving a sensitivity of 10.6 MHz/% relative humidity (RH). Overall, this work overcomes the inherent limitation of data transmission in conventional humidity sensors and provides a novel and instructive strategy for the advancement of green low-permittivity electronic substrate materials.

Cellulose-ZIF67 adsorption of emulsified oily wastewater was systematically studied. • Excellent environmental tolerance under high salinity and pH 6-10 range. • Synergistic electrostatic adsorption and hydrophobic interactions for emulsified oil removal. • Real textile oil fume wastewater achieved 68.77% oil and 92.42% turbidity removal. • Real marine diesel wastewater achieved 80.60% oil and 80.57% turbidity removal. Emulsified oily wastewater has emerged as a major challenge in the field of water treatment due to the difficulty of oil-water separation and its severe impact on environmental ecosystems. Cellulose offers excellent modifiability and biodegradability, while metal-organic frameworks have demonstrated unique advantages in oil-water separation owing to their high specific surface area and tunable pore structures. In this study, a hydrophobic cellulose-based MOF adsorbent was successfully fabricated by in situ growth of ZIF67 on cellulose via diazonium chemistry, followed by depositing of hydrophobic monomers. The results showed that at dosages of 60 mg/L and 40 mg/L, the oil removal efficiencies for emulsified oily wastewater at concentrations of 300 mg/L and 150 mg/L reached 93.88% and 93.55%, respectively, while the turbidity removal efficiencies both exceeded 99.6%. The adsorbent maintained satisfactory oil removal performance under high-salinity conditions and over a pH range of 6-10. The adsorption process conformed to the Sips isotherm model and pseudo-second-order kinetics, and was characterized as spontaneous, endothermic, and entropy-driven. The interaction mechanism between the adsorbent and oil was primarily attributed to the synergistic effect of hydrophobic interactions and electrostatic attraction. The adsorbent demonstrated significant removal of esters, ethers, and siloxanes from real textile oil fume purification wastewater, as well as alkanes and cycloalkanes from marine diesel wastewater. This work systematically investigated the adsorption performance of the as-prepared adsorbent toward surfactant-stabilized emulsified oily wastewater. Its practical applicability was preliminarily evaluated using two real oily wastewaters with different compositional characteristics.

Supercapacitors are high-power-density energy storage devices essential for applications requiring rapid energy delivery. However, their practical implementation is often hindered by significant self-discharge. Functional separators capable of regulating ion transport offer an effective strategy to mitigate self-discharge without compromising electrochemical performance. In this work, a functional binary piezoelectric membrane based on cellulose acetate (CA) and poly(vinylidene fluoride) (PVDF) is fabricated via electrospinning and employed as a high-performance separator. The electrospun PVDF matrix provides intrinsic piezoelectricity, enabling the modulation of ion flux via a built-in electric field. Meanwhile the incorporation of CA significantly enhances electrolyte affinity, liquid uptake, and mechanical integrity. Benefiting from high porosity, and strong polarity, the separator delivers outstanding electrochemical performance in solid-state supercapacitors, achieving a high specific capacitance of 194.5 F g −1 at 0.5 A g −1 with over 10,000 stable cycles. Crucially, the functional separator effectively suppresses the self-discharge rate to ~18.7 mV h −1 and retains 44% of the initial voltage after 24 h, which is an approximately 28% improvement in charge retention over the commercial separator. This work demonstrates that electrospun piezoelectric CA/PVDF composite membranes are promising functional separators for next-generation supercapacitors with low self-discharge.

Dye-containing wastewater remains an important environmental concern because many synthetic dyes are persistent and potentially harmful to aquatic organisms and human health. In this work, a biomass-based adsorbent was evaluated together with a separate post-desorption photo-oxidative treatment step. Cellulose (CL) and chitosan (CS) were used to prepare cross-linked CS/CL (C-CS/CL) microspheres for dye removal from water, with glutaraldehyde (GA) used to improve the structural stability of the microspheres. The synthesized C-CS/CL microspheres exhibited improved mechanical stability and pH-dependent dye adsorption, with preferential uptake of anionic dyes (acid blue 93 and acid black 1) and lower uptake of cationic dyes (methyl violet and methyl green). After adsorption, the dyes were eluted, allowing the C-CS/CL microspheres to be reused for repeated dye removal. The dye-containing eluate was subsequently subjected to UV/H 2 O 2 treatment, resulting in partial degradation of the model dyes. Overall, the C-CS/CL microspheres enabled preferential adsorption and repeated reuse, while the separate UV/H 2 O 2 step provided subsequent treatment of the dye-containing eluate. Graphical Crosslinked chitosan/cellulose microspheres provide stable, pH-responsive adsorption of anionic and cationic dyes and retain most adsorption capacity through ten reuse cycles. Adsorption is maintained in electrolyte, binary-dye, and real-water matrices. Regeneration releases dye-containing eluate for separate UV/H 2 O 2 treatment, which provides partial dye degradation as a complementary downstream oxidation step after desorption.

Chitosan modified with quaternary phosphonium salt and sorbic acid was synthesized. • The TEO Pickering emulsions stabilized by CNC and MCS were prepared, which exhibited excellent stability. • A multifunctional film with good mechanical and barrier properties was designed. • The composite film against C. gloeosporioides can prolong the shelf life of mangoes. Mango is a popular tropical fruit valued for its flavor and nutritional richness. However, its postharvest shelf life is limited because of its climacteric nature, which leads to rapid softening and spoilage. Chitosan-based coatings suffer from limited mechanical strength and single-function antimicrobial activity. To address these limitations, a bifunctional modified chitosan (MCS) was synthesized by grafting quaternary phosphonium salts and sorbic acid onto the chitosan backbone. This MCS was then combined with a thyme essential oil (TEO) Pickering emulsion stabilized by cellulose nanocrystals (CNC) to fabricate an active composite coating (MCS-PE). The chemical structure, thermal stability, mechanical properties, and barrier properties of the composite films were characterized. The results indicated that the composite film loading with TEO at 3 μL/mL exhibited favorable tensile strength (10.94 MPa) and elongation at break (41.12%). Antibacterial assays revealed that the MCS-PE film-forming solution had excellent activity against Escherichia coli , Staphylococcus aureus and C.gloeosporioides . The coating films effectively extended the storage life of mangoes at 25 °C, as indicated by assessments of peel color, firmness, weight loss, and other physiological indices. Consequently, mangoes coated with the optimal MCS-PE3 coating film (3 μL/mL TEO) had a shelf-life extension of at least 10 days compared to the uncoated control group. The sensory acceptability of the coated mangoes, particularly regarding potential flavor alteration, should be evaluated in future studies prior to commercial application. This work demonstrates that the synergistic integration of bifunctional chemical modification and Pickering emulsion stabilization offers a promising strategy for designing next-generation fruit preservation coatings.

The cross-coupling interaction mechanisms among biomass components pose a critical challenge in pyrolysis mechanism research. In this study, β -d-glucose and 2-phenoxy-1-phenylethanol ( α -OH-PPE) were employed as model compounds for cellulose and lignin, respectively. By integrating density functional theory (DFT) calculations with experiments from synchrotron vacuum ultraviolet photoionization mass spectrometry (SVUV-PIMS), a unified and hierarchical mechanistic framework was established to elucidate the progressively evolving hydrogen transfer-mediated interactions during biomass pyrolysis. Specifically, the identified interaction pathways were categorized into three modes: (i) mutual reactant–reactant cooperative hydrogen transfer, (ii) reactant-assisted hydrogen transfer, and (iii) product/intermediate-assisted hydrogen transfer. The results demonstrated that β - d -glucose and α -OH-PPE exhibited coupled bond cleavage through a cooperative hydrogen transfer mechanism, with energy barrier lying between those of the individual component reactions. Intermediates from β - d -glucose ring-opening (e.g., hydroxyacetaldehyde) could serve as hydrogen transfer mediators to promote bond cleavage reactions like Maccoll elimination in α -OH-PPE. Conversely, phenolic products and tautomers (e.g., 2,4-cyclohexadienone) derived from α -OH-PPE pyrolysis were found to lower the energy barriers for ring-opening, dehydration and secondary reactions of β - d -glucose. Product evolution from SVUV-PIMS showed that α -OH-PPE lowered the formation temperature of 1,4:3,6-dianhydro- α - d -glucopyranose and furan derivatives from β - d -glucose, while β - d -glucose broadened the temperature range over which α -OH-PPE maintained its maximum decomposition rate. This study provides a mechanistic framework for understanding component interactions in biomass pyrolysis. Novelty and significance statement This work addresses a critical challenge in understanding biomass pyrolysis mechanisms by clarifying the microscopic cross-coupling interactions between cellulose and lignin via intermolecular hydrogen transfer reactions. The main novelty lies in the development of a unified and hierarchical mechanistic framework that organizes multiple hydrogen transfer-mediated interaction modes into a progressively evolving representation of biomass pyrolysis, categorizing them into three modes: (i) mutual reactant–reactant cooperative hydrogen transfer, (ii) reactant-assisted hydrogen transfer, and (iii) product/intermediate-assisted hydrogen transfer. This framework enables a systematic interpretation of cross-coupling evolution across the pyrolysis process, elucidating the initial reaction steps in biomass combustion. These findings provide critical insights into establishing a mechanistic foundation for understanding the combustion of complex biomass components, thereby advancing sustainable energy utilization.

Rice straw and lignin is used to from a cellulose/lignin composite membrane (CLCM) with photothermal de-icing properties. • Lignin incorporation boosts CLCM UV–Vis absorption (0.07 → 0.95), improving photothermal de-icing and UV resistance. • CLCM shortens ice slide by 72 s under 1 kW/m 2 solar radiation compared to CM. • CLCM can improve the germination rate and growth of soybean and Chinese cabbage. Agricultural films tend to freeze in low-temperature environments, causing a sharp decline in light transmission and thermal insulation properties, which severely hampers productivity in protected agriculture. The accumulation of ice layers intensifies the loss of light energy and heat dissipation, posing a severe threat to the stability of the crop growth environment. Here, a cellulose/lignin composite membrane with photothermal de-icing properties was prepared by green recombination technology using agricultural waste rice straw as raw materials. The activated cellulose is prepared by the extraction and activation process using rice straw as raw material, and the lignin/cellulose composite membranes is prepared by solution blending, scraping, and solution replacement. Due to the introduction of lignin, the CLCM exhibited a marked enhancement in absorption intensity (from 0.07 to 0.95) across the UV–visible spectrum (200–800 nm), which effectively improves its photothermal de-icing performance and UV resistance properties. Photothermal de-icing properties results show that under the solar radiation of 1 kW·m −2 , the complete sliding time of ice on the surface of CLCM is 72 s shorter than the CM, showing excellent de-icing performance. Under simulated light radiation, three temperature test point temperature in the self-made experimental device under CLCM coverage increases with the illumination time. In addition, Chinese cabbage and soybean germination rates reached 85 % and 83.3 % respectively under CLCM coverage, showing significantly stronger growth than under PE film coverage and no mulching. The developed photothermal deicing agricultural film effectively maintains optical and thermal properties by actively removing ice, providing a promising strategy to enhance the resilience of protected agricultural systems.
