▎ 摘　　要

NOVELTY - Graphene sheet combining graphite flake structure, comprises: a graphite nanoplatelet material; and a graphene material mixed in the graphite nanoplatelet material. The graphene material is present at 1-80% of the graphite nanoplatelet material. USE - The graphene sheet combining graphite flake structure is useful as heat-dissipation structure and for light and thin requirement of the current electronic products. ADVANTAGE - The graphite flake structure: has flexible property thus entire structure becomes stronger, better heat conducting effect so that heat can be rapidly dissipated from the heat source and electromagnetic shielding effect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) manufacturing the graphene sheet combining graphite flake structure, comprising adding 0.1-10 wt.% graphite nanoplatelet material into a solvent and stirring to form a well-mixed solution, adding 1-80 wt.% graphene material in the solution and stirring to form a well-mixed slurry, applying the slurry on an object and drying the slurry to form a graphite coating and pressing the graphite coating to form the graphene sheet combining graphite flake structure; and (2) slurry for manufacturing a graphene sheet combining graphite flake structure, comprising solvent, graphite nanoplatelet material comprising many graphite nanoplatelets and graphene material comprising many graphenes, where the graphite nanoplatelet material and the graphene material are mixed in the solvent.
