METHODS FOR THE DEVELOPMENT OF COMMERCIAL SCALE NANO-ENGINEERED ULTRACONDUCTIVE COPPER WIRE

摘要

When forming ultra-conductive wire, multi-walled carbon nanotubes (MWCNTs) are dispersed and de-agglomerated in hot metal. The MWCNTs are dispersed in a precursor matrix via mixing and sintering to form precursor material, which is hot- extruded multiple rounds at a predetermined temperature to form a nano-composite material. The nano-composite material is inserted into a metal bar to form a nano- composite billet (306), which is subjected to multiple rounds of hot extrusion to form an ultra-conductive material. The ultra-conductive material is subjected to one or more rounds of hot wire drawing to form an ultra-conductive wire comprising a nano- composite filament.
