Carbon nanotube 1 Carbon nanotube Carbon nanotubes (CNTs) are allotropes of carbon with a cylindrical nanostructure. Nanotubes have been constructed with [1] length-to-diameter ratio of up to 132‚000‚000:1‚ significantly larger than for any other material. These cylindrical carbon molecules have unusual properties‚ which are valuable for nanotechnology‚ electronics‚ optics and other fields of materials science and technology. In particular‚ owing to their extraordinary thermal conductivity
