Part of a unique class of materials known as nanomaterials, 1D materials like carbon nanotubes are typically only one atom thick in at least one spatial dimension.
Because carbon nanotubes have a low density for a solid of 1.3 to 1.4 g/cm 3, its specific strength of up to 48,000 kN·m·kg −1 is the best of known materials, compared to high-carbon steel's 154 kN·m·kg −1.
