graphenen.
/ˈɡrafiːn/, U.S. /ˈɡræˌfin/ Chemistry.
An allotropic form of carbon consisting of sheets one atom thick, with atoms arranged in a two-dimensional hexagonal lattice. Frequently attributive.Originally the name graphene was applied to such sheets constituting a basic structural element of graphite, fullerenes, and carbon nanotubes. Individual sheets of graphene were first demonstrably isolated by Andre Geim and Kostya Novoselov in 2004, by repeatedly stripping layers from graphite. Graphene is a very strong material and a good conductor of electricity and heat.

1985 Synthetic Metals 11 189 The agreement between the number of SbF6− anions and the number of carriers per carbon atom proves that..all the charge on graphene layers is delocalized.
1994 Science 29 July 635/2 The fibers were found to be hollow tubes consisting of concentric cylindrical graphene sheets.
2008 Sci. Amer. (U.K. ed.) Apr. 69/2 The experimental discovery of graphene led to a deluge of international research interest. Not only is it the thinnest of all possible materials, it is also extremely strong and stiff.
2016 P. J. Hazell Armour viii. 244 Graphene may be a useful protection material too, and although there have been examples of woven structures of graphene, these are still at the very small scale.
