COMPOSITE CONDUCTIVE YARN BASED ON NANOTUBES AND NANOFIBRES, CO-AXIAL MICROSTRUCTURE COMPRISING A COPPER ARRAY AND THESE NANOTUBES AND NANOFIBRES AND PROCESS FOR THE PRODUCTION OF SAID MICROSTRUCTURE

摘要

The subject of the invention is a conductive composite wire comprising at least one outer copper jacket (1), characterized in that it further comprises: a first tube (2) consisting of a first material (M1) in contact and located inside said copper casing; a second tube (3) made of a second material (M) and in contact and located inside said first tube; a fiber consisting of a third material (M) and, in contact and situated inside said second tube, the copper and the first material being immiscible with each other, the first and second materials being immiscible with each other, the second and third materials being immiscible with each other. The subject of the invention is also a copper-based coaxial microstructure characterized in that it comprises a copper sheath containing a set of nanotubes and nanofibers according to the invention and a method of manufacturing said microstructure.
