A carbon nanotube (CNT) is a tube-shaped material made from a single-layer of carbon atoms (graphene) that have a diameter measuring on the nanometre scale. The graphite layer appears somewhat like a rolled-up continuous unbroken hexagonal mesh.
Carbon nanotubes are classified in following two types:
1. SWCNTs—Single-walled carbon nanotubes
2. MWCNTs—Multiple-walled carbon nanotubes
CNTs have good chemical and environmental stability and high thermal conductivity (~3000 W/m/K, comparable to diamond). These properties, coupled with the lightness of carbon nanotubes, give them great potential in applications such as aerospace. They also have high electrical conductivity (comparable to copper).
Potential Applications: electronics (transistors, energy production and storage), electromagnetic, electro acoustic, biotechnology, medicine and others such as structural and Mechanical
