Publication number: 20080182027Abstract: The present invention is a catalytic chemical vapor deposition method and apparatus for synthesizing carbon nanotubes and/or carbon nanofibers (CNTs) on a substrate by selectively heating a catalyst for CNT synthesis on or near the surface of the substrate. Selective heating of the catalyst is achieved using an exothermic oxidation reaction on the surface of the catalyst, inductive heating from a radio frequency source, or both. Selective heating of the catalyst prevents heating of the substrate and enables the synthesis of CNTs on temperature sensitive substrates.Type: ApplicationFiled: January 30, 2007Publication date: July 31, 2008Applicant: CFD RESEARCH CORPORATIONInventor: Aleksey V.
