High-yield production of highly fluorinated graphene by direct heating fluorination of graphene-oxide.
By employing honeycomb GO with large surface area as the starting materials and using elemental fluorine, we developed a novel, straightforward topotactic route toward highly fluorinated graphene in really large quantities at low temperature. The value of F/C molar ratio approaches to 1.02. Few-layer fluorinated graphene sheets are obtained, among which the yield of monolayered FG sheet is about 10% and the number of layers is mainly in the range of 2-5. Variations in morphology and chemical structure of fluorinated graphene were explored, and some physical properties were reported.
