Carbon Nanotubes

Carbon nanotubes are a class of nanomaterials that correspond of a two-dimensional hexagonal chassis of carbon tittles, fraudulent and joined in one direction so as to form a concave cylinder. Carbon nanotubes are one of the allotropes of carbon, specifically a class of fullerenes, intermediate between the buckyballs and graphene. Besides these single- wall carbon nanotubes, the name is also used formulti-wall (MWCNT) variants conforming of two or further nested nanotubes, or of graphene-suchlike strips rolled up into multiple layers like a scroll. Individual nanotubes naturally align themselves into" ropes" held together by fairly weak van der Waals forces. While one can make nanotubes of other compositions, utmost of the exploration has been concentrated on carbon bones; so that the carbon qualifier is frequently left implicit, and the names are abbreviated NT, SWNT, and MWNT. Carbon nanotubes can parade remarkable electrical conductivity, while others are semiconductors. They also have exceptional tensile strength and thermal conductivity because of their nanostructure and strength of the bonds between carbon tittles.
