▎ 摘　　要

NOVELTY - The preparation method of graphene oxide modified material involves immersing a material in an impregnating solution, then taking out the impregnated material and carrying out irradiation, where the material includes fibers, yarns or fabrics, and the impregnating solution mainly consists of graphene oxide, a crosslinking agent, a free radical scavenger and water. USE - The method is useful for preparing graphene oxide modified material, which is useful for manufacturing a conductive device in an electronic industry, an electric power industry and an aerospace industry, where the conductive device includes an electrothermal fabric, an electromagnetic shielding fabric or a circuit board (all claimed). ADVANTAGE - The method prepares graphene oxide modified material with high conductivity, excellent antistatic property and lightweight. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the graphene oxide modified material prepared by the above method, which is an electroconductive fiber, yarn, or fabric.
