Abstract
The present invention concerns a method for growing carbon nanotubes using a catalyst system that preferentially promotes the growth of single- and double-wall carbon nanotubes, rather than larger multi-walled carbon nanotubes. Ropes of the carbon nanotubes are formed that comprise single-wall and/or double-wall carbon nanotubes.
Claims5
A rope of carbon nanotubes comprising single-wall and double-wall carbon nanotubes.
A rope of carbon nanotubes comprising single-wall and double-wall carbon nanotubes wherein at least about 30% of the carbon nanotubes are double-wall carbon nanotubes.
A rope of carbon nanotubes wherein at least about 30% of the carbon nanotubes are double-wall carbon nanotubes.
