▎ 摘　　要

NOVELTY - Preparation of graphene prepreg involves interposing graphene powder between release papers, placing resultant product in vulcanizing machine, cold-pressing at room temperature, peeling graphene sheet from resultant product by mechanical-peeling process and adhering resultant graphene sheet with semi-cured epoxy resin composite film. USE - Preparation of graphene prepreg (claimed). ADVANTAGE - The method enables simple and environmentally-friendly preparation of graphene prepreg having excellent electroconductivity and mechanical property.
