Patent ID: 8444947

Claim:
A method for making a carbon nanotube wire structure, comprising: providing a plurality of carbon nanotube arrays, each of the plurality of carbon nanotube arrays being formed on each top surface of a plurality of substrates, each of the top surfaces being in a different plane parallel with each other; drawing a plurality of carbon nanotubes from each of the plurality of carbon nanotube arrays so that a plurality of carbon nanotube films is formed, wherein an angle between the drawing direction and each of the top surfaces is about 0 degrees to about 50 degrees; passing the plurality of carbon nanotube films through an object having a hole, so that the plurality of carbon nanotube films converge at the hole of the object to form a carbon nanotube wire structure precursor; and treating the carbon nanotube wire structure precursor by at least one of a mechanical method and an organic solvent method to form the carbon nanotube wire structure.
