▎ 摘　　要

NOVELTY - Preparing fluorinated graphene material comprises (i) reacting graphene oxide, sodium hydroxide and sodium chloroacetate to convert the hydrogen atoms of the hydroxy groups in the graphene oxide into carboxy groups to obtain carboxylated graphene, reacting the carboxylated graphene, fluorine source material and silver nitrate and replacing the hydroxy group in the carboxy group of the carboxylated graphene by a fluorine atom to obtain fluorinated graphene. USE - The method is useful for preparing fluorinated graphene material. ADVANTAGE - The method does not makes obvious structural damage.
