Composite conductive cable comprising nanotubes and nanofibers, coaxial microstructure including a copper matrix and said nanotubes and nanofibers, and method for manufacturing said microstructure

摘要

A conductive composite wire includes at least one external jacket made of copper, a first tube including a first metallic material (M1) contacting and located inside the copper jacket; a second tube including a second metallic material (M2) contacting and located inside the first tube; and a fiber including a third metallic material (M3) contacting and located inside the second tube. The copper and the first metallic material are immiscible with each other, the first and second metallic materials are immiscible with each other, and the second and third metallic materials are immiscible with each other. A copper-based coaxial microstructure includes a copper sheath containing an array of nanotubes and nanofibers according to a process for manufacturing the microstructure.
