Title:
SINGLE-WALLED CARBON NANOTUBE, CARBON FIBER AGGREGATE CONTAINING THE SINGLE-WALLED CARBON NANOTUBE, AND METHOD FOR PRODUCTION OF THE SINGLE-WALLED CARBON NANOTUBE OR THE CARBON FIBER AGGREGATE
Document Type and Number:
WIPO Patent Application WO/2007/125923
Kind Code:
A1
Abstract:
Disclosed is a single-walled carbon nanotube which is useful as an industrial material such as a high-strength carbon wire, has a controlled diameter, and has a high purity, particularly a uniform single-walled carbon nanotube having a diameter ranging from 1.0 to 2.0 nm. Also disclosed is a method for production of the single-walled carbon nanotube with high efficiency, in a large scale and at low cost. The single-walled carbon nanotube has a diameter ranging from 1.0 to 2.0 nm and also has a ratio between the intensity of G-band and the intensity of D-band (IG/ID ratio) in a Raman spectrum of 200 or greater. The single-walled carbon nanotube or the like can be synthesized by a gas-flow CVD method using a saturated aliphatic hydrocarbon which is in a liquid state at ambient temperature as the first carbon source and an unsaturated aliphatic hydrocarbon which is in a gaseous state at ambient temperature as the second carbon source.
