▎ 摘　　要

NOVELTY - Preparation of graphene-modified metallic foam materials comprises placing metallic foam materials in a vacuum tube-type furnace, and sintering in non-oxidation air; and carrying out chemical vapor deposition to deposit graphene on the sintered metallic materials. USE - Method for the preparation of graphene-modified metallic foam materials (claimed). ADVANTAGE - The conductive materials have super-low density, super-high superficial area, high heat conduction, and improved thermostability and corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the graphene-modified metallic foam materials.
