Carbon Nanotubes and Graphene

Carbon nanotubes (CNTs) and graphene are allotropes of carbon which have fascinating electrical, mechanical and other physical properties. Graphene is a two-dimensional material, on a very basic level of a single layer graphite, with carbon particles arranged in a hexagonal, honeycomb framework. Carbon nanotubes are barrel shaped and empty structures, essentially, a sheet of graphene folded into a chamber. The time when they are rolled (their "chirality"), and their separation over, impact their properties. CNTs can be single-walled (SWCNTs or SWNTs) or it can be multi-walled (MWCNTs or MWNTs)
