Achieving both high sensitivity and effective temperature compensation is crucial for high-performance humidity sensors. However, integrating temperature compensation often compromises sensitivity. We develop a fiber-optic surface plasmon resonance (SPR) sensor that integrates a cellulose-based humidity-sensing module and a polydimethylsiloxane (PDMS)-based temperature-sensing module on a plastic-coated multimode optical fiber. By utilizing a highly humidity-sensitive cellulose film, we developed a sensor that delivers high sensitivity while incorporating temperature compensation. The sensor exhibits an average humidity sensitivity of -9.15 nm/RH% and a maximum sensitivity of -14.1 nm/RH% within a relative humidity (RH) range of 25%-70%. In addition, it shows a temperature sensitivity of -2.48 nm/°C between 25 °C and 45 °C. By employing a sensitivity coefficient matrix, the system achieves real-time temperature compensation, thereby significantly enhancing humidity measurement accuracy. Due to its high sensitivity, robust performance, and simple structure, the proposed sensor demonstrates strong potential for practical applications, such as human respiration monitoring and health status analysis.

A simple chemical bonding method to synthesize magnetic cellulose–poly(dopamine) (Fe 3 O 4 @ [email protected] ) was reported. The adsorption behaviors of resorcinol in aqueous solution on Fe 3 O 4 @ [email protected] were systematically investigated. As the results shown that, with the advantage of high surface area, abundant hydroxyl and amino groups of Fe 3 O 4 @ [email protected] , and the magnetic property of Fe 3 O 4 , the resorcinol can be easily and rapidly extracted from the water by magnetic attraction under investigation. The adsorption equilibrium of Fe 3 O 4 @ [email protected] for resorcinol corresponded with Freundlich isotherm, and the novel adsorbent exhibited better resorcinol removal efficiency in solutions with low pH. It was found that the resorcinol adsorption performance of Fe 3 O 4 @ [email protected] strongly depends on their surface charge concentration and specific surface area. These results provide evidences for estimating and optimizing the removal of phenols from the wastewater by using of Fe 3 O 4 @ [email protected] composites in the future.

The architecture of cellulose nanomaterials is definitized by random deposition and cannot change in response to shifting application requirements. Herein, we present a magnetic field-controlled cellulose film derived from wood that exhibits great magnetic properties and reliable tunability enabled by incorporated Fe3O4 nanoparticles and cellulose nanofibers (CNF) with a large length-diameter ratio. Fe3O4 nanoparticles are dispersed in suspensions of CNF so as to enhance the magnetic response. The plane magnetic CNF can be processed to form a three-dimensional (3D) flower-like structure along the magnetic induction line after applying an external magnet. Inspired by the fluidic transport in natural flowers, a bilayer structure was created using the 3D flower-like film as the solar energy receiver and natural wood as the water pathway in a solar-derived evaporation system. Compared with a planar cellulose film decorated with Fe3O4, the 3D structure design can greatly improve the evaporation rate from 1.19 to 1.39 kg m–2 h–1 and the efficiency from 76.9 to 90.6% under 1 sun. Finite element molding further reveals that the 3D structural top layer is beneficial for the formation of a gradient temperature profile and the improvement of the energy efficiency through the reduction of thermal radiation. The magnetically controlled fabrication represents a promising strategy for designing cellulose nanomaterials with a complicated structure and controllable topography, which has a wide spectrum of applications in energy storage devices and water treatment.

Poly(lactic acid) (PLA), a new renewable and environmentally friendly polymer material, has gained significant attention in recent years. However, its application is limited by challenges such as poor thermal stability, brittleness and limited impact resistance. At present, PLA is predominantly modified through blending, filling and copolymerization methods. Although the above modification methods can effectively improve the properties of PLA, there are still some deficiencies in some places. In this work, CNF/Ti 3 C 2 T x /PLA composites were prepared by impregnation with poly(lactic acid) (PLA) and cellulose nanofibers (CNF), a new two-dimensional material Ti 3 C 2 T x , and a complete CNF membrane as a support framework. The effects of CNF and Ti 3 C 2 T x incorporation on the thermal, mechanical and electromagnetic shielding properties of PLA were investigated using various characterization techniques including FT-IR, XRD, DSC, TGA, tensile testing and electromagnetic test characterization. The results showed that CNF can improve the thermal stability and crystallinity of PLA, where the crystallinity can reach 23.5%. CNF synergized with Ti 3 C 2 T x to improve the mechanical properties of PLA, and the tensile strength was increased by 64.29%. Furthermore, Ti 3 C 2 T x imparted electromagnetic shielding properties to PLA composites. The findings expand the application of PLA composites in the field of electromagnetic shielding.

Metal–organic frameworks (MOFs) have received widespread attention in recent years. However, the powder form of MOFs limits their large-scale applications. To facilitate the application of MOFs, mass production and shaped manufacturing of MOFs is significantly effective. Herein, a generic method based on a simple polymerization technique is proposed to prepare highly porous MOF–cellulose composite beads and the application of these composite beads in dye removal and recovery is displayed. Non-toxic solvent water and biodegradable sodium carboxymethylcellulose (CMC) were used as raw materials in the synthesis method. In addition to maintaining the crystallinity and porosity of the MOFs embedded in the cellulose matrix, the unique three-dimensional lamellar interconnected structure provides good mechanical properties for the composite beads. To demonstrate the practicality of these composite beads, a recycling processing system was built as a proof-of-concept device. MIL-100/CMC-HD can effectively degrade more than 95% of the dye and can be recycled multiple times. The superiority of the MOF–cellulose composite beads is highlighted by their ease of recycling and storage compared to MOF powder. Graphical abstract MOF/carboxymethylcellulose porous composite beads are synthesized in a simple one-step process. The lamellar interconnected structure not only facilitates the diffusion of contaminants in water but also provides good mechanical properties.

Solar-driven water steam generation is a promising strategy for seawater desalination and wastewater purification. However, oil contaminants commonly exist in real water resources, which drives us to design and fabricate photothermal materials with high efficient water steam generation and outstanding anti-oil-fouling ability. Herein, we developed a metal-phenolic network-coated cellulose foam (Fe 3+ /TA@CF), which exhibits not only superb hydrophilicity and underwater lipophobicity, but also achieves high water evaporation rate of ∼1.3 kg m −2 h -1 even in oil-polluted seawater under one sun illumination. In addition, Fe 3+ /TA@CF is demonstrated to be both anti-oil-fouling and anti-salt-fouling, which benefits to long-term evaporation in practical utilizations. Metal ions and oil contaminants in the condensed water vapor are almost eliminated after purification. We believe that this low-cost, biodegradable Fe 3+ /TA@CF paves a way for rationally designing and fabricating high-performance evaporator for oil contaminated water purification.

Perovskite quantum dots (PQDs) has been attracted enormous attention in optoelectronic fields, especially as highly efficient narrow-band phosphors for lighting and next-generation display devices, attributed by high photoluminescence quantum yield, tunable emission colors and high color purity. However, poor stability seriously impeded their practical applications. Here, we described a robust-stable CH 3 NH 3 PbBr 3 PQDs/Ethyl Cellulose (EC) composite films with adjustable amounts of PQDs by ligand-assisted precipitation EC in one-step. The key to the preparation of CH 3 NH 3 PbBr 3 PQDs/EC composite film is to achieve the supersaturated recrystallization of CH 3 NH 3 PbBr 3 PQDs and the dissolution of EC in toluene. Combined with experimental results and investigated material characterization unveiles that the synthetic composite film possessed very high transparency, excellent down-conversion luminescence function and strong specific absorption in the ultraviolet region, which benefits form the excellent stability & hydrophobicity of EC, and long-term stable fluorescence performance in air or water under the protection of EC. Moreover, the fluorescence intensity maintained significantly stablility even after 1000 folds. In addition, the CH 3 NH 3 PbBr 3 PQDs/EC composite film exhibited excellent flexibility, which made our composite film showed great potential in the field of flexible display.

Bamboo cellulose has been widely used as reinforcement for polymers or template material for composites manufacturing due to its high strength-weight ratio and biodegradability. In this work, effects of four extraction methods on the morphology, structure and properties of bamboo cellulose are investigated, including hydrothermal extraction (HT), standard alkali extraction (SA), ambient condition extraction (AC) and two-stage extraction (TS). Among these methods, pure cellulose I with high crystallinity and intact single cell morphology can be obtained by TS. The cellulose extracted by SA have complete cell morphology, mixed structure of cellulose I and II, outstanding toughness and thermal stability. By contrast, there are hemicellulose residues of the cellulose extracted by HT. But it performs better in mechanical properties and thermal stability. The advantage of AC is that the pure cellulose I can be obtained without thermal history, but treatment time is relatively long, resulting in the damage of cellulose morphology.

Cellulose products such as textile, paper, package and so on are apt to breed bacterial. In this study, AA-PHMB antibacterial agent was synthesized innovatively. It was grafted onto cellulose by the addition polymerization of carbon carbon double bonds and hydroxyl groups to prepare cellulose antibacterial film with excellent performance. The structures, elements, mechanical properties and antibacterial activities of films were studied. The results showed that C N absorption at 1631 cm −1 of guanidine and the amide group absorption peak at 1554 cm −1 appeared on cellulose graft copolymers ; employing SEM-EDS, a great quantity of deposited materials, with the elements of C, O and N, were observed on the grafted cellulose. The graft percentage of cellulose-AA-PHMB was about 62%. Compared with unmodified cellulose films , the mechanical properties of PHMB-AA-cellulose film were lower, and the crystallinity of the PHMB-AA-cellulose film was lower than that of original cellulose film. The modified film as a raw material had a good inhibitory effect on Escherichia coli and Staphylococcus aureus was proved by bacteriostatic experiments. Under the condition of continuous culture for 15 days, it still had a good bacteriostatic effect on the above strains, and therefore the cellulose-AA-PHMB films were long term antibacterial effect materials.

Eco-friendly cellulose microfibers were modified by mussel-inspired polydopamine coating layer and a cellulose/polydopamine (CPD) membrane was fabricated by a facile and cost-effective papermaking process. It was demonstrated that CPD membrane possessed a compact porous structure, superior mechanical strength and excellent thermal dimensional stability. CPD membrane was explored as a lithium-ion battery separator with its superior mechanical strength, low-cost and favorable electrochemical properties. Lithium cobalt oxide/graphite cell using CPD separator displayed the best cycling stability and rate capability compared with those of commercialized polypropylene separator and pristine cellulose separator. Furthermore, alternating-current impedance of the cell with CPD separator presented minor variation of 9 Ω after the 100th cycle indicating an excellent interfacial stability of the cell. These excellent performances could endow CPD membrane as a very promising application as a high performance lithium-ion battery separator.

Attributed to low cost, renewable, and high availability, cellulose-based aerogels are desirable materials for various applications. However, mechanical robustness and functionalization remain huge challenges. Herein, we synthesized a recoverable, anisotropic cellulose nanofiber (CNF) / chitosan (CS) aerogel via directional freeze casting and chemical cross-link process. The chitosan was performed as strength polymers to prohibits the shrinkage and retains the structural stability of 3D cellulose nanofiber skeleton, endowing the composite aerogel with satisfactory deformation recovery ability (without loss under 60 % stress cycled 100 times). The CNF/CS composite aerogel has ultralow density (∼8.4 mg/cm 3 ), high temperature-invariant (above 300 °C) and high porosity (98 %). The CNF/CS aerogel demonstrates anisotropic thermal insulation properties with low thermal conductivity (28 mWm −1 K −1 in rational direction and 36 mW m −1 K −1 in the axial direction). Moreover, the composite aerogel (water contact angle ∼148°) exhibited outstanding oil/water selectivity and high absorption capacity (82–253 g/g) for various oils and organic solvents. Therefore, the multifunctional CNF/CS composite aerogels are potential materials for thermal management and oil absorption applications.

Chiral nematic cellulose nanocrystal (CNC) structural colored materials are the focus of extensive research in recent years on account of their unique helical structure and excellent optical properties . However, the general weak mechanical properties and poor water-resistance of CNC limit its utility. Here, we fabricated highly flexible, water-resistant chiral nematic CNC/Poly(ethylene glycol) diacrylate(PEGDA) composite films , which was realized by co-assembling CNC and PEGDA precursor then via UV curing to construct a three-dimensional crosslinking network. Due to the water stimulus-responsive feature of the CNC and PEGDA, the CNC/PEGDA (8/2) composite film could be used as a water-content detector, photonic paper. In addition, it could produce different crosslinking degrees by coating the PEGMA solution or not, which could be applied to an anti-counterfeit label. The composite film with excellent stability of cycles is expected to be a promising candidate in optical sensors, display, and security fields.
