Methods of making carbon nanotube films, layers, fabrics, ribbons, elements and articles
First Claim
1. A method of making an article, comprising:
- applying carbon nanotube growth catalyst on to a surface of a substrate;
subjecting the substrate to a chemical vapor deposition of a carbon-containing gas to grow a non-woven fabric of carbon nanotubes, wherein the nanotubes of the fabric are substantially parallel to said surface of the substrate;
selectively removing portions of the non-woven fabric according to a defined pattern; and
providing first and second electrodes in contact with respective first and second portions of the patterned non-woven fabric to create the article, wherein the patterned non-woven fabric forms a conductive trace between the first and second electrodes.

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.
