Abstract Scope The addition of graphene (GN) to copper (Cu) has shown to enhance the physical properties of copper. Charge conduction in these nanocomposites is controlled by the microstructure of copper as well as nanoscale interfacial phenomena between the GN and Cu, effects of both of which are investigated in this study. Combinations of different carrier density and mobility in Cu-GN composites are first analytically investigated. Secondly, GN-Cu samples with electrical conductivities surpassing copper by as much as 10% were fabricated. The microstructures of these samples were experimentally examined using electron backscatter diffraction (EBSD). Finally, in-situ conductivity measurements of the Cu-GN interfaces were carried out. These measurements are correlated to the microstructure of the samples and provide new insights into transport mechanisms in nanocarbon-metal composites.
