Abstract
Official abstract text for this publication.
Provided is a display device having an antistatic film made of a conductive coating liquid composition. The conductive coating liquid composition includes 10 to 100 parts by weight of a silane sol based on 100 parts by weight of a carbon nanotube dispersion liquid composition, and 0.1 to 5 wt % of a polar solvent based on 100 wt % of the conductive coating liquid composition.
First claim
Opening claim text (preview).
What is claimed is: 1. A conductive coating liquid composition comprising a carbon nanotube dispersion liquid comprising 0.05 to 20 wt % of carbon nanotubes, 0.02 to 40 wt % of a polyacrylic acid resin, 50 to 99.93 wt % of a straight-chain alkanol having 2 to 5 carbon atoms, and 0.1 to 2 wt % of at least one additional dispersant, which is an acrylic block copolymer dispersant, based on 100 wt % of the carbon nanotube dispersion liquid; 10 to 100 parts by weight of a silane sol based on 100 parts by weight of the carbon nanotube dispersion liquid; and 0.1 to 5 wt % of a polar solvent based on 100 wt % of the conductive coating liquid composition. 2. The conductive coating liquid composition of claim 1 , wherein the polar solvent has a polarity of 10 or higher. 3. The conductive coating liquid composition of claim 2 , wherein the polar solvent comprises at least one selected from n-methyl pyrolidone (NMP), dimethyl sulphoxide (DMSO), and dimethyl formamide (DMF). 4. The conductive coating liquid composition of claim 1 , wherein the silane sol comprises an alkoxysilane compound, an acid catalyst, an alcohol-based solvent, and water. 5. The conductive coating liquid composition of claim 4 , wherein the silane sol comprises 20 to 60 wt % of the alkoxysilane compound, 10 to 70 wt % of the alcohol-based solvent, and 5 to 60 wt % of water based on the total weight of the silane sol. 6. A display device comprising an antistatic film comprising the conductive coating liquid composition according to claim 1 .
