▎ 摘　　要

NOVELTY - Preparing fluorinated graphene comprises (i) performing mechanical stripping treatment to the expanded graphite to obtain the multi-layer structure graphene; (ii) subjecting the obtained multi-layer graphene to fluorination treatment, reacting multi-layer structure graphene obtained in the step (i) with fluorinated multi-layer structure graphene prepared by fluorine-containing substance; and (iii) fluorinated multi-layer structure graphene obtained in the step (ii) is processed by mechanical stripping treatment to obtain the fluorinated graphene. USE - The method is useful for preparing fluorinated graphene. ADVANTAGE - The method: ensures exfoliate graphite to become multi-layer graphene and then perform subsequent processing; ensures stripping process i.e. easier to implement, and the peeled layer is more complete when compared with directly fluorinating graphene or graphene oxide; is to first fluorinate multi-layer graphite microchips, easy to fluoride, efficient, and has safe fluorination process.
