▎ 摘　　要

NOVELTY - Two-dimensional carbon-metal configuration composite material is obtained by coaxial configuration of metal foil with concentration of 20-90 vol.% and carbon material with concentration of 10-80 vol.%, where the metal foil sheet comprises aluminum foil or surface-modified copper foil, and the carbon material comprises graphite paper, flake graphite, graphene nanosheet and/or graphene film. USE - Two-dimensional carbon-metal configuration composite material useful in thermal management application (claimed). ADVANTAGE - The composite material ensures the isotropy of two-dimensional carbon metal composite material in transverse section, has high thermal conductivity in longitudinal direction, improves the thermal conductivity of material, and solves the problem of mismatch between thermal conductivity and thermal expansion of thermal management material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the two-dimensional carbon-metal configuration composite material, involving (a) performing annealing reduction on metal foil to obtain annealed metal foil, (b) rolling annealed metal foil and carbon material stack to single-core coaxial cylinder blank, (c) performing hot isostatic pressing sintering process on single-core coaxial cylinder blank under argon protection to obtain carbon-metal composite blank, and (d) removing cladding from carbon-metal composite blank, and performing hot extrusion at 400-600 degrees C or 700-1000 degrees C to obtain two-dimensional carbon-metal configuration composite material.
