Graphene, as the thinnest, toughest and best conductive nano material found at present. It is a two-dimensional crystal composed of carbon atoms stripped from graphite material with only one layer of atom thickness. Known as “black gold”, it is “the king of new materials”. Scientists even predicted that graphene “will completely change the 21st century”.

Graphene is being used by more and more industries. Many years ago, people discovered steam, which brought human society into the steam age; Later, the emergence of electric power made people enter the electric age. In modern society, new material has been found: graphene, which is known as the king of new materials. People say that graphene is a revolutionary and magical material in the future. Countless praises are attributed to graphene. So what material is graphene and what’s the magic?
Graphene is an isomer (form) in which single-layer carbon atoms are arranged in a hexagonal lattice. It is the basic structural element of many other isomers of carbon, such as graphite, diamond, carbon, carbon nanotubes, and fullerenes.
Graphene is a material made of carbon atoms in the form of sp ² The hexagonal two-dimensional carbon nanomaterial with honeycomb lattice composed of hybrid orbits is also the lightest material in the world. It has excellent optical, electrical, and mechanical properties. It has very important application prospects in materials science, energy, biomedicine, and so on.
In 2009, Andre Geim and Konstantin Novoselov discovered the integer quantum Hall effect in monolayer and bilayer graphene systems and the quantum Hall effect at room temperature, respectively. Before that, physicists usually thought that thermodynamic fluctuations did not allow human and two-dimensional crystals to exist at finite temperature, so this discovery immediately shocked the academic community of condensed matter physics, and they won the Nobel Prize.
After graphene is electrified, the total conversion rate of effective electric energy is more than 99%. Coupled with special superconductivity, it can ensure the stability of heating performance, so it is very suitable for application in the new heating industry.
Graphene can be said to be a substitute for silicon. When it is found that it has strong conductivity, graphene must have a place in electronic products, and graphene is the material with the best conductivity known at present. Ultra micro transistors can be manufactured to produce the next generation of supercomputers. Its stable carbon element and higher electron mobility can enable future computers to obtain higher speeds. Graphene has excellent optical, electrical, and mechanical properties. It has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery. It is considered to be a revolutionary material in the future.
In addition, in biomedicine, bacterial cells can not grow on graphene, but human cells will not be damaged. Therefore, this characteristic of graphene can be used to make bandages, food packaging, antibacterial medical clothing, bedding, etc.
Graphene is the thinnest and hardest substance that has been found in the world. Jeffrey, an American engineer, vividly compares the strength of graphene: cover a graphene sheet as thin as food preservative film on a cup. If you want to pierce it with a pencil, you need an elephant standing on the pencil. See here, its hardness can be imagined.
The incredible physical properties of graphene are actually used in various thought experiments. If it can be made with at least one meter long threads, some scientists believe that this graphene can be woven together, strong and flexible enough to become the pillar of the cosmic elevator.
