Abstract
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.

A method of de-agglomerating and dispersing multi-walled carbon nanotubes (MWCNTs) in hot metal and forming ultra-conductive wire, comprising:
- dispersing and aligning the MWCNTs in a precursor matrix via mixing and sintering to form precursor material;
- hot-extruding the precursor material at a predetermined temperature to form a nano-composite material;
- inserting nano-composite material into a metal bar to form a nano-composite billet (306);
- subjecting the nano-composite billet to multiple rounds of hot extrusion to form an ultra-conductive material;
- and
- subjecting the ultra-conductive material to one or more rounds of hot wire drawing to form an ultra-conductive wire comprising a nano-composite filament.
