Graphene is composed of carbon atoms with sp2. It is a kind of two-dimensional material that formed as Hexagonal honeycomb lattice and has the thickness of only one atom.
It is currently the thinnest and strongest material known in the world. It is so thin — 0.335 nm – that you have to stack up 200,000 pieces of graphene film to get the thickness of a hair.
For a long time in the past, graphene was considered a hypothetical structure that cannot stand alone. Until 2004, two physicists Andre Geim and Konstantin Novoselov of the University of Manchester in the UK had successfully separated graphene from the graphite. The professors had won the Nobel Prize in Physics in 2010.
