| Abstract Scope |
Copper-graphene composite (CGC) conductors have been widely considered as a potential alternative for a pure Cu conductor. Yet, their electrical performance as well as underlying mechanisms are still elusive. This presentation highlights an axially bi-continuous graphene-copper composite conductor (ACGC) that achieves significantly enhanced electrical and thermal properties among CGC conductors. This work investigates the underlying mechanism of Gr-enhanced properties by preparing and characterizing Gr on three different types of pure Cu matrices, including foils, foams, and wires. The results suggest that the enhanced electrical conductivity of CGCs is positively correlated with the continuity of graphene, a high Gr-to-Cu ratio, and tightly confined electron motion by Gr. The impressive electrical conductivity of ACGC, combined with the fundamental understanding of the underlying mechanisms, is crucial for designing and manufacturing the next generation of high-performance CGC conductors for emerging applications. |
