ABOUT GRAPHENE

Graphene has emerged as one of the most promising nanomaterials because of its unique combination of properties: it is not only one of the thinnest but also strongest materials; it conducts heat better than all other materials; it is a great conductor of electricity; it is optically transparent, yet so dense that it is impermeable to gases – not even helium, the smallest gas atom, can pass through it. These amazing properties, and its multifunctionality, make graphene suitable for a wide spectrum of applications ranging from electronics to optics, sensors, and biodevices.

Graphene Sheets

When carbon forms sheets when it bonds to three other carbon atoms, they are called graphene.

The sheets of graphene in graphite have a space between each sheet and the sheets are held together by the electrostatic force called van der Waals bonding.

Sheets of graphene held together by van der Waals bonding make graphite.

Graphene sheets are composed of carbon atoms linked in hexagonal shapes with each carbon atom covalently bonded to three other carbon atoms. Each sheet of graphene is only one atom thick, and each graphene sheet is considered a single molecule. Graphene has the same structure of carbon atoms linked in hexagonal shapes to form carbon nanotubes, but graphene is flat rather than cylindrical.

A simple sheet of graphene has noteworthy properties due to a quantum phenomenon in its electron structure called Dirac cones. The system becomes even more interesting if it comprises two superimposed graphene sheets, and one is very slightly turned in its own plane so that the holes in the two carbon lattices no longer completely coincide. For specific angles of twist, the bilayer graphene system displays exotic properties such as superconductivity.

Graphene Flakes

Similar to carbon nanotubes, the properties and characteristics of Nano Graphene Flakes should outperform all other nanomaterials on the market and is intended for aerospace, automotive, energy, marine, electronics, construction, medical and telecommunications applications.

Graphene Flakes demonstrate thermal conductivity five times that of copper, a capability that provides fast thermal dissipation. These also provide electrical conductivity similar to copper yet the material’s density is four times lower, resulting in lighter weight components.

Graphene Flakes can be produced as oxide free pristine Graphene flake products in thicknesses ranging from 0.34 to 100 nanometers and widths of 0.5-20 microns in length.

Graphene INK

The graphene ink has three unique qualities which make it very important; it’s a good conductor of electricity, highly flexible and has optical transparency. This is a major step towards production of cheap and foldable electronics.

Graphene ink could be used to manufacture foldable electronic devices in the foreseeable future. It may also may help in the development of new wearable technology and offer a whole new generation of technology to customers.
