content tips: Graphene Introduction graphene is a kind of planar thin film with hexagonal honeycomb lattice composed of carbon atoms in SP2 hybrid orbit, which is only two-dimensional material with the thickness of one carbon atom. Graphene has always been considered as a hypothetical structure and cannot exist stably alone. Until 2004, physicists Andre Haim and Konstantin Novoselov of the University of Manchester in the United Kingdom successfully separated graphene from graphite in experiments, and confirmed that graphene can exist alone. The two people also cited \ Right graphene is currently the thinnest and hardest nano material in the world. It is almost completely transparent and absorbs only 2.3% light; Thermal conductivity up to 5300 w / m ·
