▎ 摘　　要

NOVELTY - A graphene thermal radiation coating comprises 40-80 pts. wt. polymer resin, 5-15 pts. wt. graphene, 1-8 pts. wt. one-dimensional carbon nanomaterial, 1-8 pts. wt. thermally conductive metal powder, 0.5-5 pts. wt. dispersant, 0.5-5 pts. wt. defoamer, and 100-200 pts. wt. inert solvent. The thermally conductive metal powder is chosen from silver, copper and aluminum, and has a particle size of 1-20 mu m. USE - Graphene thermal radiation coating coated on electronic device used in aviation, aerospace and military fields (claimed). ADVANTAGE - The graphene thermal radiation coating has excellent heat dissipation function, and is prepared by simple process at low cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene thermal radiation coating, which involves mixing polymer resin, graphene, one-dimensional carbon nanomaterial, inert solvent and dispersant to obtain a mixed material, grinding and dispersing the mixed material to obtain graphene thermal paste, adding thermally conductive metal powder, defoamer and inert solvent to graphene thermal paste, and mixing.
