Abstract
A carbon nanotube yarn includes a number of carbon nanotube yarn strings bound together, and each of the carbon nanotube yarn strings includes a number of carbon nanotube bundles that are joined end to end by van der Waals attractive force, and each of the carbon nanotube bundles includes a number of carbon nanotubes substantially parallel to each other. A method for making the carbon nanotube yarn includes soaking the at least one carbon nanotube yarn string drawn out from a carbon nanotube array in an organic solvent to shrink it and then collecting it.
Claims10
A method for making a carbon nanotube yarn, the method comprising the steps of:
- (1) providing a carbon nanotube array;
- (2) drawing out at least one carbon nanotube yarn string from the carbon nanotube array;
- (3) treating the at least one carbon nanotube yarn string using an organic solvent in a manner such that the at least one carbon nanotube yarn string is formed into a single strand of carbon nanotube yarn.
A carbon nanotube yarn comprising:
- a plurality of carbon nanotube yarn strings juxtaposedly attached to each other, the carbon nanotube yarn strings each comprising a plurality of carbon nanotube bundles which are joined end to end by van der Waals attractive force, and each of the carbon nanotube bundles comprising a plurality of carbon nanotubes substantially parallel to each other.
