is practically a one atom thick layer of carbon atoms, densely packed in a hexagonal (honey comb) lattice. The carbon-carbon bond length in graphene is about 0.142 nanometers. It is already known that it has unbelievable strength and conductivity, both of which are a result of its structure.

Application of graphene layer :

Graphene an be used to make composites in Polymers, Rubber and Metals. These materials can be made lighter, stronger, more durable and extremely resistant. The composites can be made electrically conductive and withstand extreme levels of temperature and pressures.
