Abstract

The invention discloses a beta-cyclodextrin cross-linked graphene functional cotton fiber and a preparation method thereof. The preparation method comprises the following steps: dipping a cotton fiberinto an oxidized monochlorotriazine-beta-cyclodextrin solution with a mass friction of 1%-10%, and reacting at 60-80 DEG C for 30-300 minutes, so as to obtain monochlorotriazine-beta-cyclodextrin grafted cotton fiber; and dipping the monochlorotriazine-beta-cyclodextrin grafted cotton fiber into aminated graphene ethanol dispersion liquid with a mass friction of 1%-10%, adding a certain amount ofa cross-linking agent, and stirring at a constant speed at the normal temperature for 60-600 minutes, so as to obtain the beta-cyclodextrin cross-linked graphene functional cotton fiber. By utilizingoxidized monochlorotriazine-beta-cyclodextrin as a cross-linking agent, the cotton fiber can be endowed with certain properties of electric conduction, antibiosis, ultraviolet protection, flame retardance, washing resistance and the like by aminated graphene.

Description

technical field [0001] The invention relates to a β-cyclodextrin cross-linked graphene functional cotton fiber and a preparation method thereof, belonging to the field of textile materials and functional nanometer materials. Background technique [0002] Since the discovery of graphene by two scholars from the University of Manchester in 2004, the research boom of graphene is in the ascendant. Graphene is made of carbon atoms with sp 2 The two-dimensional nanomaterial of the hexagonal honeycomb lattice composed of hybrid orbitals 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. It has excellent optical, electrical, thermal, and mechanical properties. It has a lot of research and applications in the fields of optoelectronic devices, biomedical materials, and adsorption materials. Graphene has only been discover...
