What material is graphene and what functions does it have?

Graphene is a single-layer sheet material formed of carbon atoms, which has extremely high electrical and thermal conductivity and mechanical strength. Its functions: 1. Graphene can be used as a new material for electronic devices, such as flexible displays, smartphones, etc.; 2. Graphene can improve the performance of lithium-ion batteries and supercapacitors, and can also be used as an anode catalyst in fuel cells; 3. Graphene has mechanical properties such as light weight and high corresponding strength; 4. Graphene can be used to prepare biosensors by changing surface properties as a tumor treatment drug; 6. Graphene can be made into high-strength concrete and refractory ceramics.
