COMPOSITION CONTAINING CARBON NANOTUBES, CATALYST FOR PRODUCING CARBON NANOTUBES, AND AQUEOUS DISPERSION OF CARBON NANOTUBES

Document Type and Number:

WIPO Patent Application WO/2010/101205

Kind Code:

A1

Abstract:

Disclosed is a composition containing carbon nanotubes which meets all of the following conditions 1 - 4. 1) When observed via transmission electron microscopy, at least 50 out of every 100 carbon nanotubes are double-walled carbon nanotubes. 2) The carbon nanotubes have an average outer diameter in the range of 1.0 - 3.0nm. 3) During thermogravimetric analysis at an atmospheric temperature increase of 10°C / minute, a high temperature combustion peak is at 700 - 850°C, and the relationship between low temperature weight loss (TG(L)) and high temperature weight loss (TG(H)) is TG(H) / (TG(L) + TG(H)) ≧ 0.75. 4) The composition containing carbon nanotubes has a volume resistance value between 1.0 X 10-2Ω∙cm and 1.0 X 10-4Ω∙cm, inclusive. The disclosed composition containing carbon nanotubes primarily has double-walled carbon nanotubes with high electrical conductivity and high heat resistance.
