Highly Exfoliated Graphite Fluoride as a Precursor for Graphene Fluoride Dispersions and Films

We synthesized highly exfoliated graphite fluoride of approximate composition C 2 F by treating highly exfoliated graphite with ClF 3 .The formed material was found to be dispersible in solvents giving 1 to 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.(
