Use of graphene

Graphene is a new material of a single-layer sheet structure composed of carbon atoms. It is a planar film composed of a carbon atom and a sp2 hybrid orbital composed of a hexagonal honeycomb lattice, and has a two-dimensional material having a carbon atom thickness. Graphene has always been considered a hypothetical structure and cannot be stabilized alone until 2004, when the physicists at the University of Manchester, Andre Geim and Konstantin Novoselov, Graphite was successfully isolated from graphite in the experiment, and it was confirmed that it could exist alone. The two also won the 2010 Nobel Prize in Physics for their "creative experiment in two-dimensional graphene materials." Moreover, graphene is also produced in nature. In 2014, a carbonaceous chondrite in China was found to have the energy efficiency mechanism of the Higgs particle field. In this case, the self-assembly bending of carbon crystals was found. Nanographene, the energy efficiency of the electron quantum of carbon atoms, forms natural graphene. The carbon atom "graphene" discovered in China makes it possible to see the growth of graphene, which is of great significance. The overview graphic is the natural graphene found in China.
Graphene is known as the thinnest and hardest nano material in the world. It is almost completely transparent and absorbs only 2.3% of light; its thermal conductivity is as high as 5300 W/m·K, higher than that of carbon nanotubes and diamonds, at room temperature. Its electron mobility is over 15000 cm2/V·s, which is higher than that of carbon nanotubes or silicon crystals. Its resistivity is only about 10-6 Ω·cm, which is lower than that of copper or silver. It is the material with the lowest resistivity in the world. Because of its extremely low resistivity, electron migration is extremely fast, so it is expected to be used to develop a new generation of electronic components or transistors that are thinner and faster. Since graphene is essentially a transparent, good conductor, it is also suitable for making transparent touch screens, light panels, and even solar cells.
At present, the battery made of graphene is also constantly developing. It uses a lithium battery to rapidly shuttle a large amount of movement between the surface of the graphene and the electrode, and develops a new energy battery.
