Synergetic optimization of strength and electrical conductivity in graphene/Cu wire with bimodal grain size distribution

ABSTRACT In this study, graphene (Gr)/Cu wires with unimodal and bimodal grain size distributions were prepared by cold-drawing process. The relationship between microstructure evolution, mechanical properties, and electrical conductivity was systematically studied. In the fabricated wires, the bimodal grain structure is more conducive to the formation of high-density nano twins and 9 R phase, which can significantly improve the tensile strength while maintaining high electrical conductivity.
