Abstract
A fluorographene and preparation method thereof are provided. For the said fluorographene, the fraction of F is 0.5<F %<53.5% in weight and the fraction of C is 46.5%<C %<99.5% in weight. The method comprises the following steps: providing the graphite; preparing the graphene oxide with the graphite; mixing the graphene oxide with the compound containing fluorine by weight ratio of 1:1˜100:1 in anaerobic environment, reacting at 200˜1 000° C. for 1˜10 hours then cooling down to obtain the said fluorographene. The above-mentioned method using graphite to prepare the graphene oxide, then making use of the reaction of graphene oxide with the compound containing fluorine under a certain temperature has simple process and can prepare fluorographene conveniently.
