Title:
CARBON NANOTUBE COMPOSITE MEMBRANE AND CARBON NANOTUBE DISPERSION
Document Type and Number:
WIPO Patent Application WO/2018/225863
Kind Code:
A1
Abstract:
Provided are: a CNT composite membrane that can yield an excellent electrical connection in a CNT network, said CNT composite membrane having exceptional electrical performance and exceptional durability; and a CNT dispersion. The carbon nanotube dispersion according to an embodiment of the invention includes a polyacid that functions as a dopant and a dispersant of the carbon nanotubes, the carbon nanotube dispersion has a carbon nanotube concentration of 0.005 to 1 wt.% and a polyacid concentration of 0.005 to 5 wt.%, contains the carbon nanotubes and the polyacid at a weight ratio of 1:1 to 1:5, and the carbon nanotubes are formed by removing regions in which carbon nanotubes are in contact with one another so that the polyacid surrounds the periphery of the carbon nanotubes.
