Title:
METHOD FOR MANUFACTURING CARBON NANOTUBE AQUEOUS DISPERSION
Document Type and Number:
WIPO Patent Application WO/2021/065432
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a carbon nanotube aqueous dispersion with good dispersion characteristics. The method for manufacturing a carbon nanotube aqueous dispersion according to the present invention includes: a step for mixing carbon nanotubes, carboxymethylcellulose, and water to prepare a liquid mixture; and a step for dispersing the carbon nanotubes, contained in the liquid mixture, by using an aqueous counter collision method, wherein the ratio of the mass of the carboxymethylcellulose to the mass of the carbon nanotubes in the liquid mixture is at least 1/7.
