Electrical Conductivity of Copper‐Graphene (Cu‐Gr) Composites: The Underlying Mechanisms of Ultrahigh Conductivity
is the specific surface area of a CGC; and (3) Δσ becomes more pronounced when a Cu matrix has a curved cross-section. This work reveals the fundamental mechanisms of how Gr influences the overall electrical conductivity of CGCs and, therefore, is a crucial step toward designing and manufacturing high-performance CGC conductors for emerging applications.
