SYNTHESIS OF COILED CARBON NANOTUBES BY MICROWAVE CHEMICAL VAPOR DEPOSITION

摘要

The present invention provides a coiled carbon nanotube and a method for its manufacture. The coiled carbon nanotube comprises a specific non-hexagonal/hexagonal carbon ring ratio, a specific pitch, and a specific diameter. The invention employs a microwave chemical vapor disposition system with novel processing conditions and specialized catalysts to synthesize the coiled carbon nanotubes.
