Graphene is an allotrope of carbon consisting of a single layer of atoms arranged in a hexagonal lattice nanostructure. The name is derived from "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon contains numerous double bonds. Each atom in a graphene sheet is connected to its … See more Structure of graphite and its intercalation compounds In 1859, Benjamin Brodie noted the highly lamellar structure of thermally reduced graphite oxide. In 1916, Peter Debye and Paul Scherrer determined … See more Monolayer sheets In 2013 a group of Polish scientists presented a production unit that allows the manufacture of … See more A rapidly increasing list of production techniques have been developed to enable graphene's use in commercial applications.
