Graphenic carbon particle dispersions and methods of making same

Abstract:

Dispersions of graphenic carbon particles are produced using a polymeric dispersant. The polymeric dispersant includes an anchor block comprising 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, para-nitrobenzoic acid, hexanoic acid, 2-ethyl hexanoic acid, decanoic acid and/or undecanoic acid. The polymeric dispersant also includes at least one tail block comprising at least one (meth)acrylic acid alkyl ester.
