Patent ID: 7226695

Claim:
A method for producing a composite material for electrode containing a polymer having a quinoxaline structural unit represented by formula (1): (wherein R 1 to R 4 , which may be the same or different, each independently represents a hydrogen atom, a halogen atom, a hydroxyl group, an alkyl group having from 1 to 20 carbon atoms which may have a heteroatom, an alkenyl group having from 2 to 20 carbon atoms, an alkynyl group having from 2 to 20 carbon atoms, an aryl group which may have a substituent, a carboxylic acid or carboxylic acid ester group having from 1 to 20 carbon atoms, a nitro group, or a sulfonic acid or sulfonic acid ester group, R 1 to R 4 each may have a linear, branched or cyclic structure; X represents a heteroatom alone or an aryl group having from 2 to 20 carbon atoms which may have a heteroatom; and k represents an integer of 0 to 5) on the surface of an electrically conductive carbon material, comprising dehydration condensation polymerization of a tetramine derivative having two o-diaminophenyl groups and a tetracarbonyl compound having two α, β-dicarbonyl groups in the presence of an electrically conductive carbon material.
