United States Patent 8003165

posted on Aug 29, 2011 10:32AM

Catalyst for carbon nanotube growth

Abstract:
Nanoparticles are coated using thick-film techniques with a catalyst to promote the growth of carbon nanotubes thereon. In one example, alumina nanoparticles are coated with a copper catalyst. Such nanoparticles can be selectively deposited onto a substrate to create a field emission cathode, which can then be utilized within field emission devices.
