▎ 摘　　要

NOVELTY - A high mechanical strength mother-of-pearl structure-imitated film comprises graphene oxide, chitin fiber and chitosan, where chitin fiber is from dried shrimp skin and graphene oxide is from graphite powder. USE - High mechanical strength mother-of-pearl structure-imitated film. ADVANTAGE - The film uses cheap and readily available graphite powder and dried small shrimps as raw materials, has high tensile strength and flexibility, good material hardness, and stable performance, and is simple and convenient to prepare. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of film comprising mixing raw materials and stirring to obtain precursor solution; and adding to culture plastic Petri dish, heating, and drying to form film layer.
