▎ 摘　　要

NOVELTY - Fluorinated graphene preparation involves utilizing Hummers method for producing graphene oxide dispersion liquid. Graphene oxide dispersion liquid is passed through liquid nitrogen to obtain a solid graphene oxide. Solid graphene oxide is frozen and dried to obtain a honeycomb lattice of graphene oxide. Fluorination of honeycomb graphene oxide is carried out with fluorine gas in presence of inert gas at higher temperature to obtain a fluorinated product. The fluorinated product is cooled to room temperature to obtain the desired product. USE - Method for preparing fluorinated graphene (claimed). ADVANTAGE - The method enables preparing fluorinated graphene with good heat resistant properties in a simple, safe and economical manner.
