Abstract
Methods of making carbon nanotube films, layers, fabrics, ribbons, elements and articles are disclosed. Carbon nanotube growth catalyst is applied on to a surface of a substrate. The substrate is subjected to a chemical vapor deposition of a carbon-containing gas to grow a non-woven fabric of carbon nanotubes. Portions of the non-woven fabric are selectively removed according to a defined pattern to create the article. A non-woven fabric of carbon nanotubes may be made by applying carbon nanotube growth catalyst on to a surface of a wafer substrate to create a dispersed monolayer of catalyst. The substrate is subjected to a chemical vapor deposition of a carbon-containing gas to grow a non-woven fabric of carbon nanotubes in contact and covering the surface of the wafer and in which the fabric is substantially uniform density.
