Single walled carbon nanotubes shortened as SWNTs are an allotrope of sp2 hybridized Carbon. Individual Single walled carbon nanotubes are stronger than steel, and also have current conveying limits of 109 amp/cm2, higher than those of Au or Cu. Furthermore, semiconducting species show higher electron mobility than silicon. As a rule, the coverings formed with Single walled carbon nanotubes are exceedingly transparent in the visible and IR locales of the spectrum, letting Single walled carbon nanotubes supplant ITO as the transparent conductor for solar cells, displays and electroluminescent lighting and so on. Room temperature heat conductivity of a single nanotube might be practically identical to that of diamond or in-plane graphite, which are for the most part thought to show the highest measured thermal conductivity of any known material at normal temperatures. Most Single walled carbon nanotubes have a diameter of about 1 nanometer, and can be a large number of times longer. The structure of a Single walled carbon nanotubes can be conceptualized by wrapping a one-particle thick layer of graphite called Graphene into a consistent barrel.

Single walled carbon nanotubes are an essential assortment of carbon nanotube, for many of Single walled carbon nanotube's properties change fundamentally with the (n,m) values, and this reliance is non-monotonic (search for Kataura plot). Specifically, their band gap can differ from zero to around 2 eV and their electrical conductivity can demonstrate metallic or semiconducting behavior. Single-walled nanotubes are likely to help make gadgets very small. The most essential building piece of these frameworks is the electric wire, and Single walled carbon nanotubes being really thin can be astounding transmitters.
One valuable use of SWNTs is in the improvement of the main intermolecular field-effect transistors (FET).
Single walled carbon nanotubes are to bring large impacts in electronic applications.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from:  https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread that i

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs)  have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product.
