▎ 摘　　要

NOVELTY - A graphite/graphene composite material (11) comprises flat-shaped graphite particles and graphene aggregates. The flat-shaped graphite particles are laminated such that basal surfaces are laminated over one another using the graphene aggregates as a binder. The graphene aggregates comprise deposits of mono-layer or multilayer graphene. USE - Graphite/graphene composite material is used for forming heat-collecting component, heat transfer component and thermal radiation component of thermal radiation system (all claimed). ADVANTAGE - The graphite/graphene composite material has high thermal conductivity, crystallinity, orientation property, bending strength and volume density, and excellent impact resistance, and can freely adjust the lamination direction. The thickness of the flat-shaped graphite particles in the lamination direction can be increased. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) thermal radiation system, which comprises the heat-collecting component for absorbing heat from a heat generator, a heat-transfer component for transmitting heat from the heat-collecting component to a thermal radiation component, and thermal radiation component for dissipating heat received from the heat transfer component. The heat-collecting component, heat-transfer component and/or thermal radiation component comprise the graphite/graphene composite material; and (2) manufacture of graphite/graphene composite material, which involves mixing the flat-shaped graphite particles and graphene aggregates, filling the obtained mixture in a mold to obtain a laminate flattened graphite particles such that the basal surfaces are laminated over one another using the graphene aggregates as binder, and cutting and processing the laminate such that the lamination direction of the flat-shaped graphite particles appears as a cross-section. DESCRIPTION OF DRAWING(S) - The drawing shows a top view, a front view and a side view of the graphite/graphene composite material in which XZ-type columnar graphite/graphene composite material is integrated with silicone rubber.
