Sustainable fluorescent elastomers derived from cellulose, coumarin, and plant oil were designed. • The mechanical properties of cellulose graft copolymers can be systematically manipulated. • These sustainable elastomers show typical blue fluorescence emission under UV irradiation. The development of sustainable functional materials from renewable resources is a critical pursuit in modern materials science. In this work, we report a novel class of sustainable fluorescent elastomers fabricated by grafting a coumarin derivative, 7-acryloyloxy-4-methylcoumarin (AMC), as the fluorescent chromophores and a plant oil-based polymerizable monomer, lauryl acrylate (LA), from cellulose backbone via homogeneous reversible addition-fragmentation chain transfer (RAFT) polymerization. In this architecture, the rigid cellulose acts as the backbone, LA plays the role of soft segments to provide the stretchability, while AMC serves as the hard segments to enhance the tensile strength and endow the matrix with fluorescent performance. The resulting cellulose- graft -poly(7-acryloyloxy-4-methyl co umarin- co -lauryl acrylate) (Cell- g -P(AMC- co -LA)) copolymers exhibit tunable mechanical properties and strong fluorescence emission. This work demonstrates a feasible strategy for converting renewable natural cellulose into sustainable fluorescent elastomers by integrating coumarin and plant oil derivatives, providing new insights into the development of fluorescent materials from bio-derived resources.

Efficient loading of liquid small molecules (LSM) on nanofibrous membranes is crucial for multifunctional integrated high-performance air filtration. However, due to the coupled influence of intermolecular interactions on the manufacturing process, it remains highly challenging to coordinately optimize the sustained release effect of LSM and the structure of the membrane. Here, a one-step green electrospinning strategy based on the adaptation between hydrogen bonding and van der Waals forces is proposed. Ethanol and water are used as solvents to avoid toxicity. Ethyl cellulose provides abundant hydrogen bonding sites to reduce the release kinetics of menthone, while the van der Waals forces of menthone contribute to enhancing jet splitting behavior. Under an applied voltage of 24 kV, a feeding rate of 800 μL/h, a needle-to-collector distance of 15 cm, and a relative humidity of 50 ± 3%, the vein-like nanofibrous membranes are efficiently fabricated to enable the sustained release of menthone, achieving high-performance PM 0.3 filtration with a refreshing effect. The membrane exhibits a tensile strength of 0.90 MPa and an elongation at break of 11.77%, indicating adequate mechanical performance. Its quality factor (QF) is 1.83 times higher than that of the N95 mask. The use of completely bio-based materials and degradability makes the membrane more environmentally friendly. Furthermore, the efficient sustained release of menthone ensures a refreshing effect that lasts over 10 h. This research provides an efficient strategy for the green manufacturing of functional materials for high-performance personal protection.

Aqueous zinc-ion batteries (ZIBs) are regarded as a promising candidate for the next-generation energy storage system. As a gel electrolyte with tunable chemistry, polyacrylamide hydrogels suffer from insufficient mechanical strength and limited capability to regulate Zn 2+ transport. Herein, we address this challenge by incorporating 2D cellulose nanosheets (CNS) into a polyacrylamide network, constructing a composite gel electrolyte with heterogeneous synergistic effects. The CNS reinforces the gel through physical cross-linking with polyacrylamide chains, significantly improving its mechanical properties, while the CNS increases the transference number of Zn 2+ and suppresses side reactions, thereby favoring uniform zinc deposition and reversible stripping. Benefiting from this cooperative mechanism, the composite hydrogel enables stable cycling in Zn||Zn symmetric cells, operating for over 2800 h at 0.5 mA cm −2 and 0.5 mAh cm −2 , and the assembled Zn||MnO 2 full cell demonstrates a high-capacity retention of 88.5% after 2500 cycles at 0.5 A g −1 . Furthermore, the assembled flexible battery exhibited stable specific capacity under repeated bending, confirming its excellent mechanical flexibility. This work establishes a novel system for long-life and high-safety gel electrolyte for ZIBs, while validating the considerable promise of 2D biomass-derived nanomaterials for advanced energy storage systems.

ADP-P@Mn and ADP-P@Ni composites were prepared by the interfacial assembly of ammonium dihydrogen phosphate (ADP) with transition metal–phytic acid (PA) complexes. These composites were then mixed with cellulose fibers in an aqueous solution to produce flame-retardant paper. Morphological analysis revealed that the original ADP particles exhibited a smooth, cubic morphology; however, after functionalization with phytic acid, the particles became rougher. The presence of P–O–Mn and P–O–Ni bonds confirmed the bridging effect between phytic acid and ADP, which led to reduced crystallinity and promoted synergistic flame-retardant effects during combustion. Within all concentration ranges tested, both ADP-P@Mn and ADP-P@Ni exhibited significantly improved flame retardancy compared with pristine ADP and reduced the flame spread rate by up to 50%, showing remarkably enhanced flame-retardant efficiency. Notably, even at low concentrations, these two novel flame retardants endowed cellulose paper with self-extinguishing properties. Additionally, increased carbon and oxygen contents in residual char, along with cross-linking via P–C, P–O, and P═O bonds, indicated the formation of a dense carbonaceous layer. Consequently, ADP-P@Mn and ADP-P@Ni significantly enhanced the flame resistance of cellulose paper while maintaining its excellent writing performance, moisture resistance, and mechanical properties.

The development of printable, biocompatible, biodegradable, and cost-effective bioinks, or biomaterial inks, remains a focal point in extrusion-based bioprinting research. In this study, fish gelatin (FG) was reinforced with microcrystalline cellulose (MCC) to formulate biomaterial inks. These FG/MCC composite inks were fabricated into 3D scaffolds using an extrusion bioprinter. The influence of MCC concentration on printability was systematically evaluated. Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analyses confirmed the formation of hydrogen bonds between MCC and FG, indicating molecular-level interactions. Notably, MCC incorporation enhanced the rheological properties of the ink and significantly improved the compressive strength of printed scaffolds. Furthermore, MCC content modulated key scaffold characteristics, including porosity, degradation rate, swelling behavior, and microarchitecture. These findings demonstrate that FG/MCC composite hydrogels exhibit optimal properties for extrusion-based 3D bioprinting, offering a promising platform for tissue engineering applications.

Hydrogel sensors have experienced rapid advancements due to their sensitivity in detecting motion signals and the versatility of their synthesis strategies. However, to enhance their intrinsic performance or to provide additional functionalities necessary for complex application requirements, hydrogel sensors typically require the incorporation of various nanofillers. As demand grows for sensors that are skin-friendly, wearable, and mechanically stable, cellulose nanofibers (CNF) as a natural polymer have emerged as indispensable nanofillers. Nevertheless, despite being a widely utilized natural biomass nanofiller, CNF exhibit poor conductivity, and the second cross-linked network they form often results in the improved performance of hydrogel sensors at the cost of their electrical properties. In this study, surface-active carboxyl functional groups of CNF, which were prepared through nanofibrillation and modification with deep eutectic solvent (DES), were utilized to load the organic conductor PEDOT/PSS via electrostatic attraction. This resulted in the formation of functionalized nanofillers designated as PEDOT/PSS@OA-CNF. Subsequently, PAA/PEDOT/PSS@OA-CNF hydrogel sensors were synthesized through rapid in situ polymerization using an aqueous solution of acrylic acid (AA), photoinitiator, and polymerization under UV-light. The incorporation of PEDOT/PSS enables OA-CNF to function as a nanofiller, simultaneously enhancing both its mechanical properties (stress–strain: from 2.91 MPa and 321.23% to 4.69 MPa and 512.73%) and electrical conductivity (0.12 to 0.58 S/m), and the dual-functionalization cellulose nanofillers with improved mechanical and electrical properties of hydrogel sensors were achieved. Notably, the PAA/PEDOT/PSS@OA-CNF hydrogel sensor exhibits a high sensitivity to motion detection and long-term stability. Moreover, its compatibility with 3D printing allows for the fabrication of complex shapes, making it adaptable to various practical applications. It can precisely monitor both subtle (drinking and coughing) and large-scale (joint movement) human motions, demonstrating potential applications in human motion monitoring, flexible sensors, and stretchable electronic devices.

In response to the escalating threat of electromagnetic pollution, there has been a growing focus on the development of electromagnetic interference (EMI) shielding materials. Particularly, renewable components and proper structure are favored to design EMI shielding materials. Herein, polysaccharides (i.e., TEMPO oxidized cellulose nanofiber and cationic starch) and cellulose paper were applied to fabricate a composite with the sandwich structure of “conductor-magnet-conductor” by integrating with Ti 3 C 2 T x and Fe 3 O 4 . This cellulose-based composite exhibited good flexibility and tensile strength. The sandwich structure enhanced the electromagnetic wave loss, owing to interfacial reflection, dielectric loss, and magnetic loss. The composite achieved an EMI shielding effectiveness (SE) of 62.9 dB. It also possessed a satisfactory infrared stealth performance due to the low infrared emissivity of Ti 3 C 2 T x , which could effectively block infrared radiation from the heated object. Furthermore, the composite exhibited good Joule heating performance (reaching 104.8 °C within 25 s at 5 V). This work might provide a new pathway for the design of multifunctional cellulose-based materials.

Modern infrared detection technology and electromagnetic interference (EMI) problems spur the development of multispectral compatible defense materials. However, high-performance materials prepared with facile preparation technology are in urgent demand. Herein, we proposed a cellulose-based asymmetric hierarchical composite for dual-spectra compatible defense (i.e., EMI shielding and infrared stealth). This hierarchical composite was assembled with a TEMPO oxidized cellulose nanofiber (TOCNF)/carbon nanotube (CNT) aerogel prepared by ambient pressure drying and a TOCNF/MXene film. The assembled composite realized a maximum EMI shielding effectiveness (EMI SE) of 77.3 dB, and the absorption coefficient could reach 0.71 at most, benefiting from an “absorption-reflection-reabsorption” shielding mechanism. This composite acted as an absorption-dominated EMI shielding material that effectively mitigated the secondary reflection of electromagnetic waves. Interestingly, the asymmetric structure allowed this composite to switch to a reflection-dominated EMI shielding material when flipped easily. Furthermore, the composite exhibited outstanding infrared stealth performance, attributed to the impeded heat transfer within the aerogel layer and the inherently low infrared emissivity of the film layer. This asymmetric hierarchical structural design, based on ambient pressure drying, offers a facile strategy for developing dual-spectra compatible defense materials with switchable electromagnetic wave absorption capability.

There has been increasing public interest in physical and mental health in recent years, rendering high-performance flexible sensors a burgeoning research focus. However, currently available hydrogel sensors fail to achieve high stretchability, conductivity, and stability. In this study, polyacrylamide (PAM) served as the matrix, and a dual-cellulose hierarchical network (MCNF) was constructed using microfibrillated cellulose and TEMPO-oxidized cellulose nanofibers of differing dimensions through a photocuring method. MXene was then loaded onto this network to form an effective conductive path. This approach endowed the hydrogel with a new energy dissipation mechanism, enhancing its mechanical properties: tensile strength (116.86–277.84 kPa), strain (1923–2029%), and toughness (1.34–2.12 MJ m −3 ). Additionally, the electrical conductivity of the PCMH hydrogel can reach 4.55 S m −1 and still maintain 64% of its conductivity at −70 °C, demonstrating excellent freeze resistance. Finally, when used as a flexible sensor, it can stably and sensitively monitor the movement signals of various parts and joints of the human body, accurately identify different sounds, and expand the application of cellulose in multifunctional sensors, soft electronic devices, and skin patches.

Soilless cultivation relies on hydrogel matrices for water and nutrient management, but conventional hydrogels lose performance at low temperature and show unstable sustained release. Here this study develops an antifreeze sustained-release hydrogel (P-GTCH) that integrates l-proline (L-P) with a humic-acid-modified cellulose nanocrystal nanocomposite (CNCs-HA) for nanoenabled controlled release. L-P suppresses ice nucleation via hydrogen bonding, while CNCs-HA boosts HA loading and enables controlled transport within the cross-linked network. HA shows slow, continuous release governed by Fickian diffusion, achieving 96.7% cumulative release over 12 days at 0 °C and mitigating poor fertilizer release in cold environments. P-GTCH provides mechanical support for plant roots, and the synergistic effects of L-P and HA maintain lettuce germination above 86% at 0 °C while promoting root growth. This biobased, biodegradable platform is scalable for low-temperature soilless cultivation.

Liquid-free ion-conductive elastomers represent an attractive platform for flexible electronics by circumventing the leakage and instability inherent to conventional hydrogels and ionogels. Despite the ability of polysaccharide fillers to address the low overall performance in single-network, liquid-free ion-conductive elastomers, balancing their conflicting electrical and mechanical properties is hindered by poor filler dispersion. Here, we introduce a green water vapor-mediated regeneration strategy to construct a cellulose filler skeleton. By effectively lowering the cellulose regeneration rate to resolve structural inconsistency and surface roughness, this strategy produces a more homogeneous cellulose skeleton, thus allowing its uniform dispersion within the PDES matrix. The uniform 3D porous cellulose framework, rich in hydroxyl groups, synergistically forms a homogeneous network with polyacrylic acid. This enables effective energy dissipation by providing additional reversible hydrogen bonds and also offers stable pathways for free ion migration. The as-fabricated elastomer composite exhibits exceptional mechanical robustness with a tensile strength of 3.1 MPa, Young's modulus of 1.63 MPa and toughness of 13.0 MJ/m 3 , together with tunable ionic conductivity (1.1–3.2 × 10 −2 S/m), enhanced environmental stability, and intrinsic self-healing capability. PDES-VC-2% withstands 10,000 cycles at 200% strain without fracture, and maintains stable signal output for approximately 680 cycles. Consequently, strain sensors from this elastomer are employed for human motion monitoring, information encryption, and handwriting recognition. A battery fabricated with it as the solid-state electrolyte achieves a 0.731 V open-circuit voltage and stable 14-day operation, making it suitable for both charging capacitors and driving self-powered sensing, with both repeatability and sustainability. This work provides a sustainable strategy for constructing internal networks in ionic conductors using polysaccharides, opening new opportunities for multifunctional and environment-friendly soft iontronics.

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.
