WHAT IS GRAPHENE?

Graphene is a two dimensional material, composed of a single honeycomb layer, a hexagonal lattice of carbon atoms. It is one atom thick and yet it is the strongest and lightest material ever tested, plus it has the highest conductive qualities of any material.
Graphene has the potential to radically change our consumer world, from manufacturing processes, to many of the products we buy.

 

PROPERTIES OF GRAPHENE

1. A 2D material, one carbon atom thick.

2. The lightest of all materials.

3. The strongest material ever tested.

4. Highly conductive - for heat and electricity - almost no resistance.

5. Can be stretched and is flexible.

6. More transparent than a pane of glass.
