Document Type and Number:
WIPO Patent Application WO/2024/048354
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a carbon nanotube dispersion having excellent dispersibility of carbon nanotubes. The carbon nanotube dispersion of the present invention contains carbon nanotubes, a polymer, and a dispersion medium and is characterized in that the polymer contains a nitrile group-containing monomer unit, an alkylene structure unit, and a hydrophilic group-containing monomer unit and the rate of change ΔE in the specific absorbance before and after centrifugation, obtained by the formula: ΔE=100×(E1−E2)/E1 [%] taking the specific absorbance of the carbon nanotube dispersion as E1 and the specific absorbance of the supernatant obtained by centrifuging the carbon nanotube dispersion for one minute at 4000 rpm as E2, is less than 50%.
