NOVELTY - Preparation of graphene grafted polycaprolactam composite material, involves using graphite, acid, oxidant and caprolactam, and reacting to obtain graphene grafted polycaprolactam composite material. USE - Preparation of graphene grafted polycaprolactam composite material (claimed). ADVANTAGE - The method greatly simplifies the preparation process, significantly reduces energy consumption of strong acids and bases, and prepares graphene grafted polycaprolactam composite material at low cost under mild reaction conditions. The graphene grafted polycaprolactam composite material has thin thickness and obvious features of lamellar graphene.
