Graphene and Carbon Nanotubes Synergistically Improved the Thermal Conductivity of Phenolic Resin

Abstract

People discover the synergistic effect of graphene and carbon nanotubes on heat conduction in graphene carbon nanotubes / epoxy resin hybrid composites. In this article we added them into the phenolic resin and test the thermal conductivity. We found the thermal conductivity was increased by 6.5% in the phenolic resin by adding 0.45wt% graphene and 0.15wt% single wall carbon nanotubes (maintain the mass ratio 3:1). So if graphene and carbon nanotubes are added in proportion, thermal conductivity of phenolic resin will be improved significantly which is better than only carbon nanotubes or graphene.
