The present invention relates to a graphene-ceramic heat dissipation material having improved electrical insulation properties and resin miscibility. Since the graphene-ceramic heat dissipation material according to the present invention can secure electrical insulation while maintaining the excellent thermal conductivity of graphene, it can be applied to various heat dissipation materials requiring electrical insulation, and has a high specific surface area unique to graphene. And by improving the miscibility with the resin contained in the heat dissipation material itself due to the low compaction density, there is an effect of increasing product production efficiency or product applicability. In addition, the graphene-ceramic heat dissipation material according to the present invention is applied to various carbon materials having a planar structure such as graphene, graphite, expanded graphite, and graphene nanoplatelets to modify the shape by granulated spheroidization, thereby making the planar material It is possible to have thermal conductivity in the same direction by eliminating the difference in thermal conductivity between the horizontal and vertical directions. |
