Abstract

The invention provides a graphene composite antibacterial fiber. The graphene composite antibacterial fiber is mainly prepared by the following steps of (1) enabling N-beta-(aminoethyl)-gamma-aminopropylmethyldimethoxysilane to react with graphene oxide subjected to plasma treatment to obtain aminated graphene; (2) enabling glycidyl trimethyl ammonium chloride to react with the aminated graphene to obtain quaternized graphene with quaternary ammonium salt at the tail end; and (3) enabling a polyester fiber and the quaternized graphene to undergo dipping mixing treatment to obtain the graphenecomposite antibacterial fiber. The provided graphene composite antibacterial fiber has better antibacterial property and washability at the same time.

Description

Technical field [0001] The invention relates to a fiber, in particular to a graphene composite antibacterial fiber. Background technique [0002] Graphene is a two-dimensional nanomaterial with a hexagonal honeycomb lattice composed of carbon atoms in the form of sp2 hybrid orbitals. It is the basic unit of carbon materials such as zero-dimensional fullerenes, one-dimensional carbon nanotubes, and three-dimensional graphite. Graphene is currently the thinnest two-dimensional material in the world, with extremely excellent optical, electrical, thermal, and mechanical properties. It has a large number of research and applications in the fields of optoelectronic devices, biomedical materials, and adsorption materials. [0003] Combining graphene materials with polyester fibers can effectively improve the inherent defects of polyester fibers, endow polyester fibers with excellent electrical conductivity, antibacterial, anti-ultraviolet, abrasion resistance, and flame retardant properti...
