▎ 摘 要
NOVELTY - Graphene composite material involves dispersing graphene in an organic solvent and dispersant to obtain graphene dispersion liquid. The obtained oxide layer is removed after drying. The obtained product is soaked in a graphene dispersion liquid. The obtained product is rolled. USE - Method for preparing graphene composite material (claimed). ADVANTAGE - The method enables to prepare graphene composite material in a simple manner, and has wide applicability.
