▎ 摘　　要

NOVELTY - A chitosan fabric based foam modified graphene comprises chitosan fabric and graphene foam modified layer. The chitosan fabric is composed of modified chitosan and chitosan oligosaccharide blended fiber. The graphene foam modified layer comprises graphene foam, nano titanium dioxide and additive. USE - Chitosan fabric based foam modified graphene (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of chitosan fabric based foam modified graphene, which involves mixing chitosan fiber and chitosan oligosaccharide blended fiber in ratio of (60-80):(20-40) to form blended yarn, immersing blended yarn in a solution containing 3-chloro-2-hydroxypropyltrimethylammonium chloride, heating, stirring, ethanol washing and drying to obtain quaternary ammonium salt modified chitosan and chitosan oligosaccharide blended fiber, using quaternary ammonium salt-modified chitosan and chitooligosaccharide blended fiber as raw materials, weaving to form chitosan fabric, immersing chitosan fabric in graphene oxide solution, oscillating, taking out, drying and curing, immersing in a reducing agent and nano-titanium dioxide finishing liquid, heating reaction, taking out, vacuum drying, washing by water to remove unstable substance adhered on the surface, and drying.
