Abstract:
1. A method for manufacturing a carbon nanotube composite material comprising: providing a carbon nanotube wire structure comprising of a plurality of carbon nanotubes; applying metal to outer surfaces of the carbon nanotubes; heating the carbon nanotube wire structure in vacuum to a first temperature and a second temperature; wherein at the first temperature, the metal is fused to form a fused metal, there is a reaction between the plurality of carbon nanotubes and the fused metal to form metal carbide particles, and the carbon nanotube wire structure is decreased in diameter by about 20% to form a decreased carbon nanotube wire structure; and at the second temperature greater than the first temperature, the decreased carbon nanotube wire structure breaks to form a broken carbon nanotube wire structure and the broken carbon nanotube wire structure has at least one tip portion.
