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 |
摘要 |
It relates to high purity single-walled carbon nanotubes having controlled diameter, useful as industrial materials, including high-strength carbon wire rods, particularly uniform single-walled carbon nanotubes having diameter fallen in a range of from 1.0 to 2.0 nm, and a method for producing the same efficiently, in large amount and inexpensively. The single-walled carbon nanotube obtained is characterized in that its diameter is fallen in a range of from 1.0 to 2.0 nm, and an intensity ratio IG/ID between G-band and D-band in a Raman spectrum is 200 or more. Furthermore, those single-walled carbon nanotubes are synthesized by a gas-phase flow CVD method that uses a saturated aliphatic hydrocarbon which is liquid at ordinary temperature as a first carbon source and an unsaturated aliphatic hydrocarbon which is gas at ordinary temperature as a second carbon source. |
