“…The tensile strength of graphene oxide/chitosan fiber was 875.5 MPa, and the toughness was 17.85 MJ/m 3 (Figure ). A mixed solution of graphene oxide dispersion, chitosan acetic acid solution, and poly(vinyl alcohol) solution was used as a spinning solution, and chitosan/poly(vinyl alcohol)/graphene oxide nanofibers were synthesized by electrostatic spinning. There was a strong hydrogen bond between chitosan and poly(vinyl alcohol) molecules, and as the content of graphene oxide increased, the distance between the fibers increased, and the water droplets on the surface of the nanofiber membrane were in a moist state .…”

In recent years, the textile industry has been seeking to develop innovative products. It is a good choice to organically combine materials with superior functional characteristics and commercial textiles to form products with excellent performance. In particular, textiles made of biological functional materials are often beneficial to human health, which is an interesting research direction. As a biopolymer material, chitosan has the advantages of strong availability, low cost, excellent safety, outstanding performance, etc., particularly the antibacterial property, and has broad application prospects in the textile field. This review provides an overview of the latest literature and summarizes recent innovations and state-of-the-art technologies that can add value to textiles. To this end, preparation of chitosan fiber, synthesis of chitosan nanofiber, antibacterial activity of chitosan fiber, antibacterial activity of chitosan nanofiber, etc., will be discussed. Furthermore, the challenges and prospects of chitosan-based materials used in textiles are evaluated. Importantly, this review can not only help researchers understand the development status of antibacterial textiles, but also help researchers discover and solve problems in this field through comparative reading.

Herein, we report recent developments in order to explore chitin and chitosan derivatives for energy-related applications. This review summarizes an introduction to common polysaccharides such as cellulose, chitin or chitosan, and their connection with carbon nanomaterials (CNMs), such as bio-nanocomposites. Furthermore, we present their structural analysis followed by the fabrication of graphene-based nanocomposites. In addition, we demonstrate the role of these chitin- and chitosan-derived nanocomposites for energetic applications, including biosensors, batteries, fuel cells, supercapacitors and solar cell systems. Finally, current limitations and future application perspectives are entailed as well. This study establishes the impact of chitin- and chitosan-generated nanomaterials for potential, unexplored industrial applications.

“…In particular, the introduction of carbonaceous nanofillers and polymers that can act as molecular binders for the graphene sheets, as well as carbon precursors to fill the voids in GFs, has been suggested to achieve high-performance fibers. For example, various nanofillers such as single , and multiwalled carbon nanotubes, , vapor-grown carbon nanofibers, , aramid nanofibers, and polymer binders such as polyacrylonitrile (PAN), , polydopamine, and chitosan have been incorporated into GFs. These nanofillers successfully interconnected graphene sheets and filled microvoids.…”

Microstructure-Controlled Polyacrylonitrile/Graphene Fibers over 1 Gigapascal Strength

Controlling the microstructures in fibers, such as crystalline structures and microvoids, is a crucial challenge for the development of mechanically strong graphene fibers (GFs). To date, although GFs graphitized at high temperatures have exhibited high tensile strength, GFs still have limited the ultimate mechanical strength owing to the presence due to the structural defects, including the imperfect alignment of graphitic crystallites and the presence of microsized voids. In this study, we significantly enhanced the mechanical strength of GF by controlling microstructures of fibers. GF was hybridized by incorporating polyacrylonitrile (PAN) in the graphene oxide (GO) dope solution. In addition, we controlled the orientation of the inner structure by applying a tensile force at 800 °C. The results suggest that PAN can act as a binder for graphene sheets and can facilitate the rearrangement of the fiber’s microstructure. PAN was directionally carbonized between graphene sheets due to the catalytic effect of graphene. The resulting hybrid GFs successfully displayed a high strength of 1.10 GPa without undergoing graphitization at extremely high temperatures. We believe that controlling the alignment of nanoassembled structure is an efficient strategy for achieving the inherent performance characteristics of graphene at the level of multidimensional structures including films and fibers.
