Graphene is the primary building block of graphite. A graphite crystal is much like a deck of cards, made up of many thousands of layers of only one atom thickness and held together held together by molecular interactions called van der Waals forces. Each “card” is a layer of graphene, composed of carbon atoms arranged in a hexagonal honeycomb lattice, much like chicken wire.

Graphene is the strongest and most rigid substance known. It has the highest electrical conductivity of any substance known and can withstand temperatures well beyond current materials used in the field of electronics.
