What is Graphene?

Graphene is an allotrope of carbon consisting of a single layer of atoms arranged in a hexagonal lattice nanostructure. The name is derived from "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon contains numerous double bonds.

Graphene is the world's first 2-dimensional material and is the thinnest, strongest, and most flexible material known to exist. Graphene, a special form of carbon, can conduct electricity and heat better than anything else.  Graphene is a two-dimensional carbon nanomaterials with hexagonal honeycomb lattice composed of carbon atoms in sp² hybrid orbitals. Graphene has the most excellent optical, electrical and mechanical properties, has important application prospects in materials, processing, micronano, energy, biomedical and drug delivery , and is considered a revolutionary material in the future, it is also called "Black Gold".

Mechanical properties: Graphene is currently the thinnest material known in the world (0.34nm) and the strongest material ever proven, with up to 130gpa, at about 100 times the strength of the best steel in the world.

Electromagnetic performance: The resistance of electrons in graphene is small, currently known with the highest mobility of electron transport materials, where the motion speed of electrons reaches 1/300 of the speed of light, far exceeding the motion speed of electrons in the general conductor. High carrier mobility with 10 times the commercial silicon wafer (15,000cm2·v-1·s-1).

Thermal properties: Graphene has extremely strong thermal conductivity. The thermal conductivity of monolayer graphene can reach 5,000W/M K, which is 3 times that of pure diamond at room temperature and 12 times that of metal copper.
