What's so good about graphene

Author: Date:2020-03-10

As a new member of the carbon element family, graphene has become synonymous with "magic materials" since its birth. Top scientific research forces in various countries have rushed to it and achieved its leading position in the material industry. However, the emergence of graphyne has refreshed the popularity of the new word "graphene". The two match each other, so who is better?


Let me talk about the extraordinaryness of graphene first.


Graphene is both the thinnest and the toughest material, with a breaking strength 200 times higher than the best steel. At the same time, it has good elasticity, and the stretching range can reach 20% of its size. It is currently the thinnest and highest strength material in nature. If a hammock made of graphene with an area of 1 square meter is used, it weighs less than 1 mg and can withstand a cat of 1 kg.


Graphene has the most potential application direction at present, which is to become a substitute for silicon, to manufacture ultra-micro transistors, and to produce future supercomputers. By replacing silicon with graphene, computer processors will run hundreds of times faster.


In addition, graphene is almost transparent, absorbing only 2.3% of light.


At the same time, it is so dense that even the smallest gas atoms (helium atoms) cannot penetrate. 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 the thinnest, most powerful, and strongest conductive and thermally conductive nanomaterials found so far, is called "black gold" and is the "king of new materials". Scientists even predict that graphene will "revolutionize the 21st century" "It is possible to set off a disruptive new technology and new industry revolution sweeping the world.
