Chemistry, properties, and applications of fluorographene

Fluorographene, formally a two-dimensional stoichiometric graphene derivative, attracted remarkableattention of the scientific community due to its extraordinary physical and chemical properties. Weoverview the strategies for the preparation of fluorinated graphene derivatives, based on top-down andbottom-up approaches. The physical and chemical properties of fluorographene, which is considered asone of the thinnest insulators with a wide electronic band gap, are presented. Special attention is paidto the rapidly developing chemistry of fluorographene, which was advanced in the last few years. Theunusually high reactivity of fluorographene, which can be chemically considered perfluorinated hydro-carbon, enables facile and scalable access to a wide portfolio of graphene derivatives, such as grapheneacid, cyanographene and allyl-graphene. Finally, we summarize the so far reported applications of fluo-rographene and fluorinated graphenes, spanning from sensing and bioimaging to separation, electronicsand energy technologies.
