What is "fluorographene"

n. (context organic compound English) A fluorinated derivative of graphene produced by exposing both sides of a sheet of graphene to atomic fluorine

Fluorographene (or perfluorographane, graphene fluoride) is a fluorocarbon derivative of graphene. It is a two dimensional carbon sheet of sp hybridized carbons, with each carbon atom bound to one fluorine. The chemical formula is (CF). In comparison, Teflon ( polytetrafluoroethylene), -(CF)-, consists of carbon "chains" with each carbon bound to two fluorines.

Unlike fluorographene, graphene is unsaturated ( sp hybridized) and completely carbon. The hydrocarbon analogue to fluorographene is sp hybridized graphane. Similar to other fluorocarbons (e.g. perfluorohexane), fluorographene is highly insulating. Fluorographene is thermally stable, resembling polytetrafluoroethylene; however, chemically it is reactive. It can be transformed back into graphene by reaction with KI under higher temperature. During reactions of fluorographene with NaOH and NaSH simultaneous reductive defluorination and substitution are observed. The reactivity of fluorographene represents a facile way towards graphene derivatives.
