Document Type and Number:
WIPO Patent Application WO/2023/145612
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a CNT liquid dispersion having excellent CNT dispersibility and excellent storage stability. The present invention is a carbon nanotube liquid dispersion comprising carbon nanotubes, a water-soluble polymer having an acid functional group and water, in which the HSP distance (Ra) between the Hansen solubility parameter (HSPc) of the carbon nanotubes and the Hansen solubility parameter (HSPd) of the water-soluble polymer is 7.0 MPa1/2 or less.
