United States Patent Application

View the Complete Application at the US Patent & Trademark Office
Methods for preparing carbon nanotube layers are disclosed herein. Carbon nanotube layers may be films, ribbons, and sheets. The methods comprise preparing an aligned carbon nanotube array and compressing the array with a roller to create a carbon nanotube layer. Another method disclosed herein comprises preparing a carbon nanotube layer from an aligned carbon nanotube array grown on a grouping of lines of metallic catalyst. A composite material comprising at least one carbon nanotube layer and prepared by the process comprising a) compressing an aligned single-wall carbon nanotube array with a roller, and b) transferring the carbon nanotube layer to a polymer is also disclosed.
