Abstract:
A method for synthesizing a graphene-polyaniline hybrid composite, including oxidatively exfoliating natural graphite flakes to yield a graphene body, functionalizing the surface of a graphene substrate with aniline groups wherein the surface of the graphene body is functionalized with aniline groups via a diazonium reaction, and polymerizing the aniline groups, wherein covalently-grafted polyaniline-graphene nanocomposites are formed by in-situ polymerization of aniline in the presence of aniline-functionalized graphene oxide, an oxidant, and an acid dopant.
