| Abstract Scope |
Graphene-metal composites have been considered for a wide range of applications due to the excellent material properties of high-quality carbon materials. For example, the advantages of graphene have been integrated with pure copper for considerably enhanced electrical properties including electrical conductivity and charge carrying capability. Despite the promising results, fabrication of large-scale graphene-metal composites, while maintaining quality of graphene during fabrication, is still non-trivial process because fabrication process itself often results in mechanical and thermal damages to both metal matrix and graphene constituents. Here, we present a novel fabrication process that allows high-throughput manufacturing of graphene-metal composites through well controlled mechanical and thermal processes. Our experimental results demonstrate that our centimeter-scale graphene-metal composites offer considerably improved electrical (up to 27%) and mechanical (up to 50% and 462% increase in the tensile strength and yield strength) performances compared to their pure metal counter parts. |
