Carbon Nanotubes
|
First discovered in the early 1990s, multi-wall carbon nanotubes represent a new, crystalline form of carbon. They are tiny tubes that can comprise several concentric walls with a graphite structure. 10,000 times finer than a human hair, their diameter ranges from 1 to 60 nanometers, and their length can reach several tens of microns. Carbon nanotubes are 100 times tougher and six times lighter than steel. Their thermal conductivity exceeds that of diamonds, and, depending on their molecular structure, they can act as electrical conductors or semi-conductors.
