Cellulose nanofiber (CNF) with high crystallinity has great mechanical stiffness and strength. However, its length is too short to be used for fibers of environmentally friendly structural composites. This paper presents a fabrication process cellulose long fiber from CNF suspension by spinning, stretching drying. Isolation the hardwood pulp done using (2, 2, 6, 6-tetramethylpiperidine-1-yl) oxidanyl (TEMPO) oxidation. The effect spinning speed ratio on properties fabricated are...
The demand for flexible energy storage devices is ever increasing, and several polymer nanocomposites are widely used to fabricate them.

A chitosan-based nanocomposite film with tannic acid (TA) as a cross-linker and titanium dioxide nanoparticles (TiO2) reinforcing agent was developed solution casting technique. TA TiO2 are biocompatible chitosan, this paper studied the synergistic effect of agent. The addition enhanced ultraviolet blocking mechanical properties film. reinforcement in chitosan/TA further improved film’s compared to neat chitosan or thermal stability slightly enhanced, whereas swelling ratio decreased....
Abstract Aramid nanofibers (ANFs) are a strong and heat‐resistant nanomaterial that can be isolated from commercial para‐aramid fibers, which allow bottom‐up self‐assembly to form ordered macroscale structures like ANF films. However, the anisotropic nature of high aspect ratio ANFs is not fully exploited when fabricating films for optimal mechanical properties. In this research, direct ink writing (DIW) applied produce ANF‐assembled with arbitrary shapes, shear‐induced alignment follow...
