▎ 摘 要
NOVELTY - A graphene dissipation structure has a substrate (10) containing surfaces (I) and (II), and graphene dissipation layer (20) containing 0.1-20 wt.% surface-modified graphene nanosheets (21), 20-80 wt.% filler (25) with ratio of particle size and thickness of 2-100, and 10-50 wt.% carrier resin (23). The surface (I) is contacted with heat source(s), and graphene dissipation layer being thermally conductive is provided on surface (II) of substrate. The surface-modified graphene nanosheets are uniformly dispersed in carrier resin and contact with each other through filler. USE - Graphene dissipation structure used for heat dissipating electrical elements and devices. ADVANTAGE - The graphene dissipation structure has enhanced thermal transfer efficiency by providing additional effective contact area, and excellent thermal and electrical conductivity. DESCRIPTION OF DRAWING(S) - The drawing shows sectional view of graphene dissipation structure.
