Applications of 4′-(4-methoxyphenyl)-2,2′:6′,2”-tripyridine

A graphene composite conductive powder, characterized in that it is obtained by self-assembly of graphene material and conductive carbon material through hydrogen bonding; polypyridine compounds are adsorbed on the surface of the graphene material, and polypyridine compounds are adsorbed on the surface of the conductive carbon material. There are carboxyl compounds, the conductive carbon material does not include graphene; the conductive carbon material is selected from one or more of carbon nanotubes, carbon fibers and conductive carbon black; the polypyridine compound is selected from dipyridine-4amine , dipyridine-3-methanol, dipyridine-3-butanone, 4,4′-biphenyl-2,2-dipyridine, 4,4′-dihydroxy-3,3′-dipyridine, 4 -Chloro-6-phenyl-2,4′-terpyridine, terpyridine 4′-(4-methylphenyl)-2,2:6′,2″-terpyridine, sodium carbonate 2,2′ :6′,2″-terpyridine-4-carboxylic acid, 4′-(4-aminophenyl)-2,2′: 6′,2-terpyridine, 4-biphenyl-2,2′: 6′,2″-terpyridine, 4-chloro-terpyridine, 4′-(4-methylphenyl)-2, 2:6′,2″-terpyridine and 4-(4-methoxybenzene base)-2,2: one or more of 6,2-terpyridine; the carboxyl-containing compound is selected from polyacrylic acid, 3,5-dinitrobenzoic acid, p-methoxybenzoic acid, 4 , one of 4′-diphenyl ether dicarboxylic acid, 2,2-diphenyl acetic acid, 2,4,5-trimethoxybenzoic acid, 3,4-dimethoxybenzoic acid and phthalic acid or more; the mass ratio of the graphene material and the polypyridine compound ammonium bicarbonate is 1: (0.01~0.5), the mass ratio of the conductive carbon material and the carboxyl compound is 1: (0.01~1 ).

The polypyridine compounds adsorbed on the surface of the graphene material have intramolecular conjugated large π bonds, which can form an effective π-π conjugated system with the conjugated large π bonds in the graphene surface structure, and are exposed on the graphene surface. There is a carboxyl/pyridine hydrogen bonding force between the outer pyridine ring and the carboxyl compounds adsorbed on the surface of other conductive carbon materials, which provides a self-assembly driving force for the self-assembly behavior of graphene materials and conductive carbon, and obtains uniform coverage of the graphene material surface. There is a composite structure of conductive carbon material.
