Graphene – is a two-dimensional allotropic modification of carbon formed by a layer of carbon atoms one atom thick in the state of sp 2-hybridization and connected via σ- and π-bonds in the hexagonal two-dimensional crystal lattice. Graphene in recent years has become one of the most intensively studied materials. This is due to it's unique electrical, electrochemical, optical, mechanical and sorption properties. Applications for graphene include electronics, catalysis, sensor manufacture, capacitors, solution various biomedical tasks.

Graphene has high mechanical strength and has a very large and available specific surface area (theoretical value of 2630 m 2 / g 237), as well as high electrical conductivity, which makes this carbon nanomaterial unique. Graphene can be in the form of graphene powder or a dispersion of graphene, as well as reduced from it's oxidized form. Of particular interest is graphene deposited by the CVD method on substrates made of various materials.
