NOVELTY - Preparing nano graphite fluoride comprises taking nano graphene and placing into reaction kettle at 300-500 degrees C, the fluorine concentration is 50-100 wt.% of fluorine volume, and reacting the mixture under a nitrogen environment for 5-70 hours to obtain fluorocarbon, where the ratio of nano graphite fluorine is 0.1-1.47. USE - The method is useful for preparing nano graphite fluoride (claimed). ADVANTAGE - The method: has high reaction efficiency, reaction safety and low cost; and is suitable for industrial scale production.
