Graphene is only separated from graphite, a two-dimensional crystal composed of carbon atoms, only one layer thick. In 2004, physicists Andre Graham and Konstantin Novoselov of Manchester University in England successfully separated graphene from graphite, and proved that it can exist alone. So both of them won the 20 10 Nobel Prize in Physics. Graphene is both the thinnest material and the strongest material, and its breaking strength is 200 times higher than that of the best steel. At the same time, it has good elasticity, and the stretching range can reach 20% of its own size. It is the thinnest and strongest material in nature at present. If a piece of graphene with an area of 1 m2 is used as a hammock, its self-weight is less than 1 mg, and it can bear a one-kilogram cat. At present, the most potential application of graphene is to become a substitute for silicon, to manufacture ultramicro transistors and to produce future supercomputers. Using graphene instead of silicon, the running speed of computer processor will be hundreds of times higher. In addition, graphene is almost completely transparent and only absorbs 2.3% of light. On the other hand, it is so dense that even the smallest gas atom (helium atom) can't penetrate it. These characteristics make it very suitable as a raw material for transparent electronic products, such as transparent touch display screens, light-emitting panels and solar panels.

Graphene, as a new nano-material with the thinnest, strongest strength and strongest electrical and thermal conductivity, is called "black gold" and is the "king of new materials". Scientists even predicted that graphene would "completely change 2 1 century". It is very likely to set off a subversive new technology and new industrial revolution sweeping the world.

Graphene has no health preserving function.
