What are carbon nanotubes? Carbon nanotubes are different structural modifications of carbon. They are also cylindrical carbon molecules that have interesting properties that make them potentially very useful in many applications in many industrial fields such as nanotechnology, semiconductors, optics and many other areas of science. materials, as well as in the architectural field. They can exhibit extraordinary strength and astonishing electrical properties, and are efficient conductors of electric current and heat. Their end use may be limited due to their unknown toxicity. There are many different types of carbon nanotubes. There are, however, 2 very important types of carbon nanotubes. There must be a clear picture so that single wall systems (SWCNT) can be easily distinguished from multiple wall systems (MWCNT). Quite simply, the formation of SWCNTs was first reported in the June 17 issue of NATURE in 1993 by two differently published papers, one by Iijima and Ichihashi and the other by Bethune (of IBM, California). There are many How carbon nanotubes can be s...
