Advanced textiles made of macroscopic fibers are usually prepared from synthetic fibers, which have changed lives over the past century. The shortage of petrochemical resources, however, greatly limits the development of the textile industry. Here, a facile top-down approach for fabricating macroscopic wood fibers for textile applications (wood-textile fibers) comprising aligned cellulose nanofibers directly from natural wood via delignification and subsequent twisting is demonstrated. Inherently aligned cellulose nanofibers are well retained, while the microchannels in the delignified wood are squeezed and totally removed by twisting, resulting in a dense structure with approximately two times higher mechanical strength (106.5 vs 54.9 MPa) and ≈20 times higher toughness (7.70 vs 0.36 MJ m −3 ) than natural wood. Dramatically different from natural wood, which is brittle in nature, the resultant wood-textile fibers are highly flexible and bendable, likely due to the twisted structures. The wood-textile fibers also exhibit excellent knitting properties and dyeability, which are critical for textile applications. Furthermore, functional wood-textile fibers can be achieved by preinfiltrating functional materials in the delignified wood film before twisting. This top-down approach of fabricating aligned macrofibers is simple, scalable, and cost-effective, representing a promising direction for the development of smart textiles and wearable electronics.

Lignin-containing cellulose nanofibers (LCNFs) offer a sustainable alternative to fully delignified nanocellulose by preserving native lignin while reducing chemical and energy consumption. Herein, bamboo-derived LCNFs were prepared through a one-step maleic anhydride esterification without toxic solvents or catalysts. The resulting LCNFs exhibit high lignin content (27.14%), abundant surface carboxyl groups (1.85 mmol g −1 ), ultrafine diameters (∼2.67 nm), and high aspect ratios (>1 μm), enabling excellent dispersion and strong interfacial interactions with polymer networks. When incorporated into poly(acrylamide-co-lauryl methacrylate) hydrogels, the LCNFs function as dual-functional crosslinkers by simultaneously providing covalent anchoring sites and physical entanglement points. The synergistic interactions significantly enhance the mechanical robustness and electrical performance of the hydrogels, yielding a tensile strength of 1.12 MPa, elongation at break of 1545%, toughness of 7.33 MJ·m −3 , and electrical conductivity of 1.15 S/m. Multiscale analyses reveal that the reinforcement originates from cooperative hydrogen bonding, covalent coupling, and nanoscale network interpenetration induced by LCNFs. This work demonstrates a green and efficient strategy for converting bamboo biomass into functional LCNFs and highlights their potential as sustainable reinforcing and crosslinking components in high-performance conductive hydrogels for flexible sensing and wearable applications.

Flexible actuators, as core components of soft robots, have attracted considerable interest for converting external energy into mechanical motion. However, most existing actuators still exhibit limitations in multistimulus responsiveness, shape programmability, and mechanical stability, which severely restrict their application in complex environments. Herein, we developed a multiresponsive, programmable bilayer actuator based on MXene/cellulose nanofibers (MXC) composite film and biaxially oriented polypropylene (BOPP) tape. By leveraging the hygroscopic, photothermal, and electrothermal properties of the MXC layer alongside the thermal expansion of the BOPP layer, the actuator achieves reversible, large-angle, and highly stable bending deformations under humidity, light, and electrical actuation. By combining pattern design and macroscopic reassembly strategy, various actuators that can realize programmable 2D-to-3D complex deformations have been demonstrated. As proof-of-concept applications, we have developed several soft robots, including a biomimetic leaf, a multiresponsive smart gripper, and a biomimetic crawling beetle robot, which hold significant potential for advancing next-generation soft robotics.

Flexible hydrogel-based sensors have attracted considerable attention for applications in human motion monitoring, health management, electronic skin, and human-machine interaction. However, it remains challenging to develop hydrogel-based strain sensors that simultaneously possess good mechanical properties, self-adhesion, self-healing capability, and antibacterial activity. Herein, polydopamine-coated cellulose nanofibers (CNF@PDA) and polyaniline (PANI) were incorporated into a polyacrylamide (PAM) network to fabricate a multifunctional CNF@PDA/PANI (x) /PAM (CPP x P) hydrogel. The introduction of CNF@PDA not only enhances the mechanical strength and adhesion of the hydrogel, but also improves the dispersion stability of PANI, thereby contributing to enhanced conductivity and sensing stability. As a result, the obtained hydrogel exhibits a tensile strength of 0.073 MPa, an elongation at break of 859.3%, excellent self-healing capability, an adhesion strength of 42.73 kPa on porcine skin, and good antibacterial activity. Importantly, the hydrogel can be used as a strain sensor with high sensitivity (GF = 7.95), a rapid response of 120 ms, and excellent durability over 500 cycles. The sensor is capable of monitoring both subtle and large human motions, highlighting its great potential for applications in flexible wearable devices and intelligent sensing systems.

Biomass aerogels are attractive in various applications owing to their inherent advantages of renewability, biodegradability and eco-friendly. Herein, a novel composite aerogel of konjac glucomannan (KGM)/TEMPO-oxidized cellulose nanofibers (TOCNF)@HKUST-1 (KTA@HKUST-1) is prepared through a facile vacuum impregnation method combined with the directional freeze-drying process, which using KGM and TOCNF as raw materials. The structural analyses disclose that the KTA@HKUST-1 has a hierarchical porosity, in which HKUST-1 can provide micropores for adsorption, while the meso -/macropores from KTA act as high-speed channels to improve diffusion and mass transfer rate to transport CO 2 components into the micropores of HKUST-1. The experiment results of KTA@HKUST-1-10 (KTA@H10) show that the CO 2 adsorption capacity can reach 3.50 mmol·g −1 at 1 bar and 298 K, and the adsorption capacity retention rate as high as 91.43% after 7 cycles. In addition, the CO 2 /N 2 adsorption selectivity of KTA@H10 can reach 18.42, which has an excellent potential for selective CO 2 adsorption.

Currently, there is great interest in converting edible agro-waste, such as okara from soybean production, into value-added products. For this study, we focus on fabricating composite hydrogels from okara cellulose nanofibers (CNFs) and carrageenan (CA). We also examined the effects of TEMPO oxidation of the okara CNFs, as well as CA concentration, on the microstructure and physicochemical properties of the composite hydrogels. The water holding capacity, oil holding capacity, surface tension, gel strength , and viscoelasticity of the composite microgels increased with increasing CA concentration, and it was found that the highest values were obtained for TC-CA2 hydrogel: contact angle = 43.6° and surface tension = 45.12 mN/m, which was attributed to the formation of a more regular and dense three-dimensional gel network. All the CNF-CA microgels had highly anionic ζ-potential values (−38.8 to −50.1 mV), with the magnitude of the negative charge increasing with TEMPO oxidation and carrageenan concentration. These results suggest there would be strong electrostatic repulsion between the composite hydrogels. The composite microgels produced in our work may be useful functional materials for utilization within the food industry, thereby converting a waste product into a valuable commodity.

The ZnO/CdS nanocomposites have been successfully synthesized on the electrospun cotton cellulose nanofibers (CCNFs). ZnO nanorods (70–80 nm in diameter and 1 μm in length) are uniformly grown on the CCNFs by a simple hydrothermal method firstly and then different amount of CdS nanoparticles (20–30 nm in diameter) are loaded on the ZnO nanorods by the chemical bath deposition method. The visible light photocatalytic activity of ZnO/CdS nanocomposites is investigated by degradation of Rhodamine B under visible light irradiation, and it demonstrates that the photocatalytic performance of this composites is significantly enhanced compared with that of pure ZnO. Furthermore, the relatively narrow band gap and novel nanostructure of the composites are considered as the main reasons of this enhancement.

The influence of 2,2,6,6-Tetramethylpiperidinooxy (TEMPO) cellulose nanofibers (TCNF) on the nucleation and growth of sulfathiazole (STZ) crystals is uncovered, aiding in the precise control of drug crystal morphology. To elucidate the mechanism by which TCNF regulates the nucleation and growth of STZ crystals, cooling crystallization experiments and molecular simulations were conducted. Initially, the crystal forms of STZ in pure water were determined. Subsequently, crystallization experiments with the addition of TCNF were conducted. The experiments aimed to investigate their effects on crystal form and crystal habits. The results revealed that a pure Form III was obtained due to the hydrogen bonding interactions on the surface of TCNF. Molecular simulations helped better explain the influence on specific crystal faces. This study indicates that the influence of TCNF on the characteristics of STZ crystals is mediated through interaction with the z-axis crystal facets, leading to the formation of block-shaped crystals. In addition, the higher concentration of TCNF forms a local closed space, resulting in blocked mobility, allowing STZ molecules in the solution to grow at the defects of STZ crystallization.

In this study, a novel nanocomposite multilayers was deposited on the electrospun nanofibrous mats by an electrostatic layer-by-layer (LBL) self-assembly technique. The positively charged water-insoluble 2,9,16,23-tetraaminophthalocyanine copper (CuTaPc) and the negatively charged water-soluble poly(acrylic acid) (PAA) were alternately deposited on the surface of negatively charged nanofibrous cellulose mats. The cationic CuTaPc was synthesized and characterized by UV–Vis and Fourier transform infrared (FT-IR) spectroscopy. The template nanofibrous cellulose mats were obtained from the alkaline hydrolysis of electrospun nanofibrous cellulose acetate mats. The resultant nanofibrous mats were characterized by scanning electron microscopy (SEM) and FT-IR spectroscopy. The SEM images showed that the composite LBL structured films were homogeneously deposited on the surface of the nanofibers . The diameters of nanofibers increased with the number of deposition bilayers . The average thickness of each CuTaPc/PAA bilayer is about 10 nm. Additionally, the FT-IR spectra results also indicated that the CuTaPc and PAA were coated on the nanofibrous cellulose mats.

The commercial application of phosphorylated cellulose nanofibrils (PCNFs) is restricted by the high environmental burdens and production costs. In this study, we developed an integrated process incorporating solvent-free phosphorylation and recycled filtrate-based phosphorylation for sustainable production of PCNFs. The phosphorylation process consisting of solvent-free ball milling and heat curing was optimized, and the obtained PCNFs showed high charge content (3.78 mmol/g) and ultrafine diameter (~2.2 nm). The washing filtrates were recycled as the aqueous solutions used in heat soaking-based phosphorylation, which could be regarded as the substitute of pure urea and phosphates. Moreover, this integrated phosphorylation process exhibited enhanced environmental friendliness with an average reduction ratio of 14.7% across all impact categories, and the production cost decreased by 31.7% compared with the traditional production route, as the life cycle assessment and techno-economic analysis results revealed. This integrated process offers valuable guidance for the sustainable industrial-scale production and efficient commercialization of PCNFs.

Improving the water permeance of polyamide nanofiltration (NF) membranes without the simultaneous loss of rejection is highly desired but remains a challenge. In this work, we prepared an ultrapermeable polyamide NF membrane containing an in-situ -formed cellulose nanofibre (CN) interconnected network film between a polyamide active layer and ultrafiltration (UF) membrane support through direct addition of the CN to a piperazine aqueous solution for interfacial polymerization. Such in-situ -formed CN interlayer with high porosity can provide a large number of channels for water transport. Compared with the polyamide active layer directly supported by the UF support, the polyamide active layer supported by the CN interlayer can contribute a more effective area for water permeation. Consequently, the polyamide NF membrane exhibited a pure water permeance up to 35.7 L m −2 h −1 bar −1 while maintaining salt rejection to Na 2 SO 4 of >97%. This permeance is 2.5 times greater than that of the membrane without the CN interlayer.
