Abstract
A thermally conductive three-dimensional (3-D) graphene-polymer composite material, methods of making, and uses thereof are described. The thermally conductive three-dimensional (3-D) graphene-polymer composite material contains: (a) a porous 3-D graphene structure comprising a network of graphene layers that are attached to one another through a carbonized organic polymer bridging agent; and (b) a polymer material impregnated within the porous 3-D graphene structure, wherein the thermally conductive 3-D graphene-polymer composite material has a thermal conductivity of 10 W/m·K to 16 W/m·K.
