Abstract

We synthesized highly exfoliated graphite fluoride of approximate composition C₂F by treating highly exfoliated graphite with ClF₃. The formed material was found to be dispersible in solvents giving 1-5 layered fluorinated graphene. Dispersions successfully formed in polar organic solvents capable of establishing hydrogen bonds. The highest stability is achieved in branched alcohols such as tert-butanol. The dispersions may be further processed into thin films by vacuum filtration technique. Also, composite multilayered films of graphene fluoride and graphene may be prepared.
