Graphene is an allotrope of carbon consisting of a single layer of atoms arranged in a hexagonal lattice nanostructure. The name is derived from "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon contains numerous double bonds. (Wikipedia/Graphene) Graphene is the ultimate material. It's a single-atom layer of carbon, and that structure makes it impressive. The graphene can be fixed if there is a hole by putting the repairing piece in that hole. And then the covalent bonds connect that repairing piece in the atom layer. That kind of ability makes graphene one of the most fundamental materials in the world. "A model of a three-dimensional metamaterial.
