NOVELTY - Preparing magnetic metal/graphene wave-absorbing material based on chemical vapor deposition comprises placing cobalt ferrite nanoparticle in methane atmosphere, carrying out chemical vapor deposition reaction at 800-1000℃ for 1-30 minutes, and cooling. USE - The method is useful for preparing magnetic metal/graphene wave-absorbing material based on chemical vapor deposition. ADVANTAGE - The in-situ synthesis of the magnetic metal/graphene obtains dense multilayer graphene to prevent the oxidation of the magnetic metal, and effectively utilizes the dielectric loss of the material to prepare a wave absorbing material with wider application prospects.
