Graphene is a single layer of carbon atoms held together by sp2 hybridized carbon atom bonds. Carbon nanotubes, essentially, are rolled-up sheets of graphene.
Examples of applications
Because graphene is such a strong material, it can be used to strengthen other materials. A sheet of graphene can be rolled up to form a carbon nanotube, which resembles a microscopic straw. Only, this straw is extremely thin and extremely strong at the same time.
Having zero effective mass, it does not add to the weight of the material it enhances. Obvious applications are building materials, aerospace, and other where lightness and strength are of the essence.
Graphene can also be used to spread heat due to its high electrical conductivity. This can be especially useful in the microelectronics area, for strain sensors, for supercapacitors and batteries that can recharge quickly, solar cells, and LEDs to name a few. It also makes it ideal for high-speed quantum physics experiments.
Due to its impermeability is can be used to filter water to get clean drinking water and graphene-based paint can prevent corrosion.
