GRAPHENE BASED COMPOSITION AND GRAPHENE BASED COATINGS FOR ELECTROCHEMICAL DEVICES

摘要

The invention relates to a method for preparing a graphene based composition, which comprises the steps of: - subjecting a composition that contains water and a graphene precursor to a mechanical treatment and to a chemical treatment in order to form graphene; - separating graphene from the mechanically and chemically treated composition to form a graphene based composition, and - mixing the graphene based composition with a first coupling agent that is capable of reacting with graphene, wherein the graphene is formed by subjecting the composition comprising water and the graphene precursor to at least two mechanical treatments.
