Abstract
A method of growing carbon nanomaterials such as carbon πanotubes, carbon nanofibers, and carbon whiskers on a variety of substrates is provided which includes exposing at least a portion of the substrate surface to an oxidizing gas, followed by forming catalysts on the substrate surface, either by immersing the carbon substrate in a catalyst solution or by electrodeposition. The treated substrate is then subjected to chemical vapor deposition to facilitate the growth of carbon nanomaterials on the surface thereof. The carbon nanomaterials may be grown on a variety of substrates including carbon substrates, graphite, metal, metal alloys, intermetallic compounds, glass, fiberglass, and ceramic substrates.
