What are properties of carbon nanotubes?

High electrical and thermal conductivity – nanocarbon tubes are ideal as conductors and semi-conductors. As compared to metal conductors, nanotubes can conduct current with thousand times higher current for the same weight and, used as thermal conductors, nanotubes show better conductivity than, for example, copper.
Flexibility and tensile strength – carbon nanotubes presently include one of the most resistant materials known. A single nanotube can be stretched by 40%, i.e. several dozen more than in case of high-class carbon fibres.
Hydrophobic properties – nanotubes show hydrophobic properties and, therefore, can repel water and other liquids and are more resistant to corrosion.
Transparency – single wall nanotubes are characterised by high permeability of white light.
