▎ 摘　　要

NOVELTY - The composite has a copper foil layer fixed with two sides of a graphite layer and provided with a copper substrate. A roughening layer is provided with a double face. A surface of the roughened layer is fixed with a tumor shape copper grain structure. The tumor shape copper grain structure and the graphene layer are matched with each other. The copper substrate, a coarsening layer and the tumor shape copper grain structure are connected with each other. Maximum length of the copper foil layer is about 8 m-100 m. The coarsening layer is formed with a table area. USE - Natural graphite/copper composite. ADVANTAGE - The composite has high electromagnetic shielding effect and less heat retardant effect, and improves copper foil and graphite surface bending effect of about 180 degree and increases heat conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a natural graphite/copper composite preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a natural graphite/copper composite.
