Abstract

Provided are a fluorinated graphene oxide and a preparation method thereof. In the fluorinated graphene oxide, the mass percent of fluorine is 0.5%<F %<40%; the mass percent of carbon is 50%<C %<80%, and the mass percent of oxygen is 0.5%<O %<30%. The preparation method comprises the following steps: providing graphite; preparing graphene oxide by using the graphite; and subjecting the graphene oxide to reacting with a mixed gas of N2 and F2 at 20˜200° C. for 0.5˜24 h, to prepare the fluorinated graphene oxide. The preparation method is simple, has fewer steps, and has better prospect of application.
