Graphene, a New Materia

Graphene is a two-dimensional material composed of carbon atoms with unique physical and chemical properties. The following is a detailed introduction: Basic Properties

Structure: A single layer of graphene is composed of carbon atoms arranged in a hexagonal honeycomb lattice. At only 0.34 nanometers thick, it is the thinnest known material.

Mechanical Properties: 200 times stronger than steel, making it the strongest known material, while also possessing excellent flexibility.

Electrical Properties: Its electron mobility is 100 times that of silicon, its resistivity is lower than that of copper or silver, and its electrical conductivity is excellent.

Thermal Properties: Its thermal conductivity is as high as 5300 W/(m·K), making it the highest known material.

Optical Properties: Its light transmittance exceeds 97%, and its light absorption rate is approximately 2.3%, making it nearly transparent in the visible light range.
