Title:
CARBON NANOTUBE DISPERSION LIQUID AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2020/129872
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: an organic solvent dispersion liquid containing single walled carbon nanotubes, which exhibits excellent dispersibility of the single walled carbon nanotubes and good stability over time, is unlikely to undergo re-aggregation, and has a low viscosity; and a method for producing same. The present invention is a carbon nanotube dispersion liquid which contains at least carbon nanotubes, a polymer dispersing agent and an organic solvent, and is characterized in that the dispersion liquid contains 0.01-10 mass% of carbon nanotubes, the carbon nanotubes include 75 mass% or more of single walled carbon nanotubes having a short axis length of 0.1-50 nm and an aspect ratio of 100 or more, and the viscosity of a preparation liquid, which is obtained by preparing the dispersion liquid so that the content of the carbon nanotubes is 0.2 mass%, is less than 500 mPa·s.
