Effect of particle size on mechanical and anisotropic thermal conductivity of copper-reduced graphene oxide composites

Copper-reduced graphene oxide composites having good anisotropic thermal conductivity and hardness values fabricated via flake powder metallurgy route. SEM was performed to examine the microstructure of powders and also different composites. Anisotropic thermal diffusivity and micro-hardness test we...
