Graphene is made of a single layer of carbon atoms that are bonded together in a repeating pattern of hexagons. Graphene is one million times thinner than paper; so thin that it is actually considered two dimensional. Carbon is an incredibly versatile element.
These single layers of carbon atoms provide the foundation for other important materials. Graphite â or pencil leadâ is formed when you stack graphene. Carbon nanotubes, which are another emerging material, are made of rolled graphene. These are used in bikes, tennis rackets and even living tissue engineering.raphite â or pencil leadâ is formed when you stack graphene.
