The graphene family has a new member: fluorographene, an atom-thick sheet of carbon in which a fluorine atom is attached to every carbon atom. The material is effectively a two-dimensional analogue of Teflon.
Rahul Nair and Andre Geim at the University of Manchester, UK, and their co-workers made the material by exposing a sheet of graphene to fluorine atoms. Unlike graphene, which has high electrical conductivity, fluorographene exhibits high resistance, making it a candidate insulating material for electronic applications.
With its outstanding thermal and chemical stability, and mechanical properties that exceed those of steel, fluorographene could be used in similar ways to Teflon.
