Effect of Graphene Nanoplatelets (GNPs) on Properties of Pure Copper

Graphene nanoplatelets (GNPs)/copper composites has been prepared by conventional powder metallurgy. Although GNPs/Al composites are widely studied, homogeneous dispersion of GNPs is still a big challenge for the researchers, which limits its use in practical applications. Our novel nano-processing route is free of ball milling which can damage the structure of GNPs during mixing. Therefore, our method can be an alternative of ball milling and it has a great potential for the synthesis of Cu based matrix nano-composite which is considered good for engineering applications. Nevertheless, the interface of GNPs/Cu plays a critical role in electrical resistivity in such a way that by increasing the GNPs/Cu interface the electrical resistivity increased.Nonetheless the hardness of the composite was increase by the introduction of GNPs.
