▎ 摘　　要

NOVELTY - Preparation of fluorinated graphene comprises taking graphene, putting in reaction kettle at 100-500 degrees C, and reacting with 10-100 vol.% fluorine under nitrogen mixed gas environment for 5-50 hours at fluorocarbon ratio of 0.1-1.3. USE - Method for preparing fluorinated graphene (claimed). ADVANTAGE - The method has good concentration control, high conversion rate, simple process with high safety and strong practicability, which fits for industrial production.
