Abstract Scope |
The power losses associated with the electrical resistance of copper (Cu) have generated considerable interest in the development of advanced conductors that incorporate carbon nanotubes (CNTs) into Cu matrix―ultra-conductive Cu (UCC) composites―to increase energy efficiency in various industrial and residential applications. To meet this demand, we developed an electrospinning strategy to fabricate UCC composites with electrical and mechanical performance exceeding that of Cu. Our approach involves electrospinning of polymer solutions containing CNTs onto Cu substrates, followed by thermal treatment to achieve a uniformly distributed CNT layer. Following additional Cu deposition, Cu-CNT-Cu composites demonstrated similar electrical conductivity, higher current carrying capacity, and improved mechanical properties compared with those of Cu. We scaled up the process to make meter long samples. 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. |
