▎ 摘　　要

NOVELTY - Preparing fluorinated graphene and fluorinated carbon nanotubes with controllable fluorine content, comprises adding graphene and 1,4-diiodoperfluorobutane or carbon nanotubes and 1,4-diiodoperfluorobutane into ampoule bottle, mixing well, freezing under liquid nitrogen, vacuumizing and finally calcining to obtain fluorinated graphene or fluorinated carbon nanotubes. USE - The method is useful for preparing fluorinated graphene and fluorinated carbon nanotubes with controllable fluorine content. ADVANTAGE - The method: synthesizes fluorinated graphene and fluorinated carbon nanotubes through gas-solid phase reaction, has low equipment requirements, low raw material toxicity, strong operability, and controllable fluorine content of product; and is simple.
