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 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. (doi: 10.5562/cca1972)
