TLDR
The strengthening mechanism of the RGO is investigated by a double cantilever beam test using the graphene/Cu model structure and the yield strength of the 2.5 vol% RGO/Cu nanocomposite is 1.8 times higher than that of pure Cu.Abstract:
RGO flakes are homogeneously dispersed in a Cu matrix through a molecular-level mixing process. This novel fabrication process prevents the agglomeration of the RGO and enhances adhesion between the RGO and the Cu. The yield strength of the 2.5 vol% RGO/Cu nanocomposite is 1.8 times higher than that of pure Cu. The strengthening mechanism of the RGO is investigated by a double cantilever beam test using the graphene/Cu model structure.read more
