Title:
OXIDIZED CARBON NANOTUBES AND OXIDIZED CARBON NANOTUBE DISPERSION
Document Type and Number:
WIPO Patent Application WO/2023/008164
Kind Code:
A1
Abstract:
Provided are oxidized carbon nanotubes having excellent dispersibility in water and dispersion stability and an oxidized carbon nanotube dispersion containing these oxidized carbon nanotubes. The oxidized carbon nanotubes contain oxidized single-walled carbon nanotubes and the number of the oxidized single-walled carbon nanotubes accounts for 51% or more of the total number of the oxidized carbon nanotubes. In the X-ray diffraction measurement, the full width at half maximum of the diffraction peak intensity at 2θ of 20-30°of the oxidized carbon nanotubes is 8.5 or less.
