▎ 摘　　要

NOVELTY - Three-dimensional (3D) carbon-metal composite material (100) comprises carbon-based foam (foam) (10) including a multiple of pores; and a metal micropowder (20) positioned in the multiple of pores. USE - The 3D carbon-metal composite material is useful as electromagnetic wave shielding material in energy storage system, a solar cell, fuel cell, and absorber of toxic organic solvents, and for next-generation communication and electronic devices e.g. Fifth Generation (5G) or Sixth Generation (6G), and electrochemical devices. ADVANTAGE - The 3D carbon-metal composite material exhibits electromagnetic wave shielding and excellent heat dissipation properties by increasing the electromagnetic wave absorption capacity and heat transfer rate by forming a porous structure through the fusion of carbon and metal fine powder; and can be processed into various dimensions to exhibit excellent electrical conductivity, chemical stability, and high surface area of more than 1000 m2/g. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing 3D carbon-metal composite material comprising preparing a mixture by mixing carbon-based foam with metal micropowder; and subjecting the mixture to chemical vapor deposition (CVD). DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of 3D carbon-metal composite material.
