Graphene is a single atom layer of extraordinary strength

Carbon atoms bonded in a two-dimensional honeycomb sheet are two hundred times stronger than steel

Graphene consists of a single planar layer of carbon atoms arranged in a hexagonal honeycomb lattice. Despite being only one atom thick, strong sp2 covalent bonds make graphene roughly 200 times stronger than structural steel by weight. It also conducts electricity and heat with exceptional efficiency.
