Abstract

A method of making a carbon nanotube fiber by combining a carbon nanotube and a non-surfactant organic solvent to form carbon nanotubes dispersed in the nanotube solution. A substrate is contacted with the nanotube solution to form a nanotube coated substrate and the nanotube coated substrate may be recoated numerous times to apply additional nanotube coatings to the substrate. The nanotube coated substrate is contacted with an acid solution, aqueous solution and an alcohol source and dried. The nanotube fiber is drawn from the nanotube coated substrate. In some instances, the nanotube fiber is twisted as it is drawn. The carbon nanotube may be a single-walled nanotube, double-walled nanotube, multi-walled nanotube, or a mixture thereof with less than 100 Ohm per sq and/or about 90% transmittance or less than 90% transmittance at about 400-700nm wavelength.
