Title:
METHOD OF PRODUCING CARBON NANOTUBE DISPERSION
Document Type and Number:
WIPO Patent Application WO/2015/045417
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method which, even without the use of a dispersant, allows efficiently producing a dispersion comprising uniformly dispersed carbon nanotubes. This method of producing a carbon nanotube dispersion is characterized by involving a step for bringing an aligned carbon nanotube aggregate formed on a substrate into contact with a solvent, and a step for separating the aligned carbon nanotube aggregate from the substrate in the solvent, wherein the carbon nanotubes configuring the aligned carbon nanotube aggregate fulfill the relation between the average diameter (Av) and the diameter distribution (3σ) of 0.20 < (3σ / Av) < 0.60, and the average length is greater than or equal to 100μm.
