▎ 摘　　要

NOVELTY - A graphene dispersion comprises a graphene material, and a polymerizable monomer comprising a structure containing a portion (p1) comprising at least one benzene ring at one end of the structure and a portion (p2) having polarity at another end of the structure. USE - Graphene dispersion is used for producing graphene reinforced polymer (claimed) e.g. thermosetting polymer or photopolymerized polymer. ADVANTAGE - The graphene dispersion has improved dispersibility. The graphene dispersion is prepared at room temperature without requiring additional dispersant. The graphene reinforced polymer obtained using the graphene dispersion has improved performance such as mechanical property and gas-impermeability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene reinforced polymer, which is obtained by polymerizing the graphene dispersion.
