FIELD: chemistry.
SUBSTANCE: dispersions of graphene carbon particles are obtained using a polymeric dispersant. The polymeric dispersant includes an anchor block containing glycidyl(meth)acrylate, 3,4-epoxycyclohexylmethyl(meth)acrylate, 2-(3,4-epoxycyclohexyl)ethyl(meth)acrylate, allyl glycidyl ether and mixtures thereof reacted with a carboxylic acid comprising 3-hydroxy-2-naphthoic acid, paranitrobenzoic acid, hexanoic acid, 2-ethylhexanoic acid, decanoic acid and/or undecanoic acid. The polymeric dispersant also includes at least one tail block containing at least one (meth)acrylic acid alkyl ester.
EFFECT: provision of increased electrical conductivity.
