The liquid-phase extraction of graphene fluoride by exfoliation of graphite fluoride in dimethylformamide and subsequent reduction with triethylsilane or zinc particles yields the corresponding chemically converted graphene, namely reduced graphene fluoride. The formation of either graphene fluoride (fluorographene) or graphene monolayers in the course of the reaction was demonstrated by several microscopy techniques. Fluorine elimination after reduction was verified by elemental analysis and infrared/Raman spectroscopy.
