"Carbon Nanomaterials such as graphene, carbon nanotubes (CNTs) and fullerenes possess extraordinary properties. The properties of nanocarbons are highly dependent upon their synthesis.
Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 and 1000 nanometres (10−9 meter) but is usually 1–100 nm (the usual definition of nanoscale).
Nanomaterials research takes a materials science-based approach to nanotechnology, leveraging advances in materials metrology and synthesis which have been developed in support of microfabrication research. Materials with structure at the nanoscale often have unique optical, electronic, or mechanical properties. Nanomaterials are slowly becoming commercializedand beginning to emerge as commodities.
Carbon nanotubes are large molecules of pure carbon that are long and thin and shaped like tubes, about 1-3 nanometers (1 nm = 1 billionth of a meter) in diameter, and hundreds to thousands of nanometers long. As individual molecules, nanotubes are 100 times stronger-than-steel and one-sixth its weight. Some carbon nanotubes can be extremely efficient conductors of electricity and heat; depending on their configuration, some act as semiconductors.
There are numerous carbon nanotubes properties and applications which take full advantage of CNTs unique properties of aspect ratio, mechanical strength, electrical and thermal conductivity."
