If you've ever drawn with a pencil, you've probably made graphene!

Accidental discovery Graphene was discovered in by Andre Geim and Kostya Novoselov in 2004. The discovery can almost be termed accidental but with years of prior studies and research. Graphene was first formed by removing flakes from a lump of graphite using sticky tape. This method is now famously called the "sticky tape method". Six years after their groundbreaking isolation of graphene, Andre and Kostya were awarded the 2010 Nobel Prize in physics for this work. What can Graphene do?? Graphene is considered as the world's first two dimensional material which basically means it is a crystalline material with a single atomic layer. This remarkable material is 200 times stronger than steel. It is also the thinnest material known-one million times thinner than the human hair. It is also the world's most conductive material as a result of its electronic structure. This could open new doors in electrical and electronics research. It's high strength means that it can be used as a composite in many areas. Graphene can also be used to improve the lifespan of the traditional lithium ion battery. Imagine going from 0 to 100% charge on your phone in under 2 minutes! Imagine a smartphone that you can wear on your wrists or a tablet that can be rolled up like a newspaper. Companies like Samsung, Apple and LG are currently investigating these technologies made possible by graphene. Graphene can also be used to further miniaturize transistors. Smaller transistors mean better performance and power consumption Seems too good to be true? Graphene is one material that promises a lot and it has received considerable attention from researchers all over the world due to its excellent properties. There is almost a rat race now to come up with the first commercial graphene product. There are also efforts to currently 3D print graphene which is a very interesting take on its production.The first commercial graphene product isn't far away! There SHOULD be some disadvantages for sure Yes there are as with any material. Graphene is a "Zero Band Gap" material - simply put, it is a material that cannot be turned off when it starts to conduct electricity. The costs associated with producing graphene commercially is still too high for commercialization. The toxicity of graphene is also quite high. Lastly, graphene is also susceptibe to an oxidative atmosphere. The pros outweigh the cons considerably, so it has all the ingredients to change our lives!
