Official abstract text for this publication.
Provided is a conductor film obtainable using a carbon nanotube dispersion liquid. The carbon nanotube dispersion liquid contains carbon nanotubes (A), a polymeric dispersant (B) including a sulfonic acid group-containing monomeric unit and an ethylenically unsaturated aliphatic carboxylic acid monomeric unit, and a solvent (C). Percentage content of the ethylenically unsaturated aliphatic carboxylic acid monomeric unit in the polymeric dispersant (B) is greater than 20 mol % and no greater than 90 mol %.
Opening claim text (preview).
The invention claimed is: 1. A conductor film obtained by drying a carbon nanotube dispersion liquid, the carbon nanotube dispersion liquid comprising: carbon nanotubes (A); a polymeric dispersant (B) including a sulfonic acid group-containing monomeric unit and an ethylenically unsaturated aliphatic carboxylic acid monomeric unit; and a solvent (C), wherein percentage content of the ethylenically unsaturated aliphatic carboxylic acid monomeric unit in the polymeric dispersant (B) is greater than 20 mol % and no greater than 90 mol %, and a number-average molecular weight of the polymeric dispersant (B) is at least 5,266,700 and no greater than 25,000,000. 2. The conductor film of claim 1 having a surface resistivity of no greater than 20 Ω/sq. 3. A conductive film comprising: a substrate; and a conductor film on the substrate, wherein the conductor film is the conductor film of claim 1 .
