Graphene

We produce low-layer graphene to order


Graphene

a two-dimensional allotropic modification of carbon formed by a layer of carbon atoms one atom thick, located in sp2 hybridization and connected to a hexagonal two-dimensional crystal lattice. Graphene can be represented as a single graphite plane separated from a bulk crystal.

Property

Graphene has a unique combination of properties:

  • Exceptional strength and elasticity
  • The highest mobility of charge carriers
  • High electrical conductivity
  • High current density
  • Record thermal conductivity
  • Highest specific surface area
  • The thinnest known material
  • Chemical stability
  • Impermeability to gases
  • Almost complete transparency
