▎ 摘　　要

NOVELTY - A graphene-coated polyacrylonitrile fiber composite material is prepared, and obtained fiber material is holded in the wet state. Cobalt/graphene composite material is prepared, and dried cobalt/graphene composite material is wetted with distilled water. The wetted cobalt/graphene and graphene-coated polyacrylonitrile fiber composite materials are mixed, distilled water is added and stirred. The fiber product is washed using distilled water, and dried at low temperature, to obtain polyacrylonitrile fiber-loaded cobalt/graphene composite material. USE - Preparation of polyacrylonitrile fiber-loaded cobalt/graphene composite material (claimed). ADVANTAGE - The polyacrylonitrile fiber-loaded cobalt/graphene composite material is efficiently prepared.
