| Abstract Scope |
To solve the power losses associated with the electrical resistance of copper (Cu) and increase energy efficiency in various industrial and residential applications, ultra-conductive Cu (UCC) composites, incorporating carbon nanotubes (CNTs) into Cu matrix, was proposed. We developed an electrospinning strategy to fabricate UCC composites with electrical and mechanical performance exceeding that of Cu. Our Cu-CNT-Cu composites demonstrated similar electrical conductivity, higher current carrying capacity, and improved mechanical properties compared with those of Cu. We are also able to scale up the process to make meter long samples and demonstrate the similar improvement as compared to the small-scale process. These performance characteristics together with the commercial viability of present approach could open new possibilities in designing advanced conductors for a broad range of electrical systems and industrial applications. |
