Abstract

A carbon material dispersed film formation composition including: a polymer that includes a triazine ring-containing repeating unit structure, such as that represented by formula (17) for example; a cross-linking agent; and a carbon material. The carbon material is well dispersed in the composition, and therefore by using this composition, a cured film in which the carbon material is well dispersed can be produced.

First claim

1 . A carbon material-dispersed film-forming composition which is characterized by comprising a triazine ring-containing polymer having a recurring unit structure of formula (1) below, a crosslinking agent and a carbon material

{wherein R and R′ are each independently a hydrogen atom, an alkyl group, an alkoxy group, an aryl group or an aralkyl group; and Ar is at least one moiety selected from the group consisting of moieties of formulas (2) to (13)

[wherein R 1 to R 92 are each independently a hydrogen atom, a halogen atom, a carboxyl group, a sulfo group, an alkyl group of 1 to 10 carbon atoms which may have a branched structure, or an alkoxy group of 1 to 10 carbon atoms which may have a branched structure; R 93 and R 94 are hydrogen atoms or alkyl groups of 1 to 10 carbon atoms which may have a branched structure; W 1 and W 2 are each independently a single bond, CR 95 R 96 (R 95 and R 96 being each independently a hydrogen atom or an alkyl group of 1 to 10 carbon atoms which may have a branched structure (with the proviso that they may together form a ring)), C═O, O, S, SO, SO 2 or NR 97 (R 97 being a hydrogen atom or an alkyl group of 1 to 10 carbon atoms which may have a branched structure); and X 1 and X 2 are each independently a single bond, an alkylene group of 1 to 10 carbon atoms which may have a branched structure, or a group of formula (14)

(R 98 to R 101 being each independently a hydrogen atom, a halogen atom, a carboxyl group, a sulfo group, an alkyl group of 1 to 10 carbon atoms which may have a branched structure, or an alkoxy group of 1 to 10 carbon atoms which may have a branched structure; and Y 1 and Y 2 being each independently a single bond or an alkylene group of 1 to 10 carbon atoms which may have a branched structure)]}.

2 . The carbon material-dispersed film-forming composition of claim 1 , wherein the carbon material includes at least one selected from the group consisting of carbon nanotubes, carbon nanohorns, fullerene, graphene, carbon black, ketjen black, graphite and carbon fibers.

3 . The carbon material-dispersed film-foaming composition of claim 1 , wherein the carbon material includes carbon nanotubes, which carbon nanotubes are individually dispersed down in size to individual nanotubes.

4 . The carbon material-dispersed film-forming composition of claim 1 , wherein the carbon material is carbon black.

5 . The carbon material-dispersed film-forming composition of any one of claims 1 to 4 , wherein the crosslinking agent is a compound that is light- and/or heat-curable.

6 . The carbon material-dispersed film-forming composition of any one of claims 1 to 4 , wherein the crosslinking agent is at least one selected from the group consisting of polyfunctional (meth)acrylic compounds, polyfunctional epoxy compounds and polyfunctional isocyanate compounds.

7 . A cured film obtained by curing the carbon material-dispersed film-forming composition of claim 1 .

8 . An electronic device comprising a substrate and the cured film of claim 7 formed on the substrate.

9 . An optical material comprising a substrate and the cured film of claim 7 formed on the substrate.
