Graphene fluoride
Did you know?
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)n. In comparison, Teflon (polytetrafluoroethylene), -(CF2)n-, consists … See more The material was first created in 2010 by growing graphene on copper foil exposed to xenon difluoride at 30 °C. It was discovered soon after that fluorographene could also be prepared by combining cleaved graphene on a See more Fluorographene is susceptible for nucleophilic substitution and reductive defluorination, which makes it an extraordinary … See more • "Chlorographene" • Organofluorine chemistry • Organofluorine compound See more The structure of fluorographene can be derived from the structure of graphite monofluoride (CF)n, which consists of weakly bound … See more Fluorographene is considered a wide gap semiconductor, because its I-V characteristics are strongly nonlinear with a nearly gate-independent resistance greater than 1 GΩ. … See more Recent studies have also revealed that, similar to fluorination, full chlorination of graphene can be achieved. The resulting structure is called See more WebAn unprecedented microwave-based strategy is developed to facilitate solid-phase, instantaneous delamination and decomposition of graphite fluoride (GF) into few-layer, partially fluorinated graphene. The shock reaction occurs (and completes in few seconds) under microwave irradiation upon exposing GF to either "microwave-induced plasma ...
