▎ 摘　　要

NOVELTY - Preparing fluorinated graphene material with adjustable fluorine content comprises (1) mixing the mixed metal salt and fluorinated graphite uniformly, where the mixing method can be grinding or ball milling, (2) adding the mixed product in a tube furnace at 550 degrees C for a period of time, and (3) subjecting the reaction product to ultrasonic peeling in a mixed solution of organic solvent and hydrogen fluoride, separating the upper layer solution by centrifugation, filtering and washing with suction, and vacuum drying to obtain fluorinated graphene. USE - The method is useful for preparing fluorinated graphene material with adjustable fluorine content. ADVANTAGE - The method has low equipment requirements, simple technological process, strong operability, and easy amplification.
