Graphene useful?You understand？（一） 

What is graphene?

Recently, a new type of building material has become popular in the market, which can also be said to be a simple application of the material with great potential to be exploited in the market. What is this material?

Graphene -- since its discovery in 2004, graphene has been highly anticipated by the scientific community for its powerful material properties. It has demonstrated properties that go beyond many existing products, and the value it brings to many professionals.So, what are his characteristics?

Property 1: 

Thermal conductivity. According to the experimental results, the thermal conductivity of graphene is as high as 5300W/m·K, higher than that of carbon nanotubes and diamond.Its structural features make it almost completely transparent, absorbing only 2.4 percent of the light.This excellent property can be directly determined to be applied in solar energy, heat dissipation materials, environmental protection industry and other fields

Property 2:

Electrical conductivity. The electron mobility of graphene exceeds 15000cm2/V·s at room temperature.Far higher than that of carbon nanotubes and the silicon crystal, and resistance is only 10 Ω 4-6 cm, lower than that of copper or silver, is one of the resistivity of small material.And this kind of characteristic can be applied to supercapacitor completely, lithium electricity, graphite and so on industry domain

Feature 3:

Ultra-thin. Graphene is one hundredth of a millionth the thickness of paper.Heim and Kostya?Novoselov's main reason for discovering graphene.The scientists continued to do this by stripping the graphite out of the graphite flakes and then taping both sides of the graphite flakes, constantly dividing them in half.In this way, you end up with a thin sheet of carbon atoms, now known as graphene.

Property 4:

Softer than rubber, it's very thin, but graphene's discoverer, 2010 Nobel Laureate In physics Andre Gehry, has made it more flexible than rubber.The material properties of graphite, Haim said, meant that it could be stretched indefinitely and bent at large angles without being broken.It is absolutely feasible to apply this feature to transparent touch screen, light plate and other industry products.
