▎ 摘　　要

NOVELTY - Preparing nickel metal modified composite carbon fiber, comprises (a) coarsening and modifying the carbon fibers with an etching solution to obtain etched modified carbon fibers; (b) modifying graphene oxide on the surface of the carbon fiber modified by etching to obtain the carbon fiber modified by graphene oxide; and (c) activating the carbon fiber modified by the graphene oxide, carrying out electroless nickel plating, carrying out reduction heating to reduce the graphene oxide on the surface of the carbon fiber to obtain a composite carbon fiber decorated with nickel metal. USE - The nickel metal modified composite carbon fiber is used as a radar stealth flexible material. ADVANTAGE - The nickel metal modified composite carbon fiber has high electrical conductivity as a whole. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for composite carbon fiber modified with nickel metal.
