Abstract
Official abstract text for this publication.
Disclosed is a carbon nanotube dispersion liquid composition for forming a conductive layer in a display device. The carbon nanotube dispersion liquid composition includes, for example, 0.05 to 20 wt % of carbon nanotubes, 0.02 to 40 wt % of a polyacrylic acid resin, and 50 to 99.93 wt % of C 2 -C 5 straight-chain alkanol, based on the total weight of the carbon nanotube dispersion liquid composition.
First claim
Opening claim text (preview).
What is claimed is: 1. A carbon nanotube dispersion liquid composition, comprising: 0.05 to 20 wt % of carbon nanotubes; 0.02 to 40 wt % of a polyacrylic acid resin; and 50 to 99.93 wt % of C 2 -C 5 straight-chain alkanol based on a total weight of the carbon nanotube dispersion liquid composition. 2. The carbon nanotube dispersion liquid composition of claim 1 , wherein the polyacrylic acid resin has a weight average molecular weight of 2,000 to 3,000,000. 3. The carbon nanotube dispersion liquid composition of claim 2 , wherein the polyacrylic acid resin has a weight average molecular weight of 8,000 to 12,000. 4. The carbon nanotube dispersion liquid composition of claim 1 , wherein the alkanol is at least one of ethanol, n-propanol, n-butanol, and n-pentanol. 5. The carbon nanotube dispersion liquid composition of claim 1 , further comprising an acrylic block copolymer dispersant. 6. The carbon nanotube dispersion liquid composition of claim 5 , wherein the acrylic block copolymer dispersant is substituted with at least one of an amine group and a carboxyl group. 7. The carbon nanotube dispersion liquid composition of claim 5 , wherein the acrylic block copolymer dispersant is contained in 0.1 to 2 wt % based on the total weight of the carbon nanotube dispersion liquid composition. 8. The carbon nanotube dispersion liquid composition of claim 1 , wherein pH of the carbon nanotube dispersion liquid composition is 1.7 to 3.5.
