Functionalized Carbon Nanotubes

Abstract

Carbon nanotubes written in short form as, CNTs are the tubes which are made from carbon having diameters in nanometers (nm) or 10 −9 meters. They can be considered as one of the best carbon allotropes like graphene, graphite, fullerene, diamond and amorphous carbon. Many experimental processes have been obtained to synthesize nanotubes in different sizeable quantities, such as chemical vapor deposition, arc discharge, and laser ablation methods. The blooming of technology related to nanomaterials is mostly happened in drug delivery, biomedical imaging, biosensing and designing of useful nanocomposites. While some more methods relating and realizing applications are continuing to evolve. Carbon nanotubes may be of two types single-wall carbon nanotubes (SWCNTs) having diameters in the range of a nanometers only or multi-wall carbon nanotubes (MWCNTs) possesses nest like structure of single-wall carbon nanotubes. These tubes can be allowed to functionalize via two general reactions such as esterification and amidation of nanotubes with carboxylic acids ends in it. General property like solubility of these tubes helps to know the properties of them by applying solution-based processes. A number of literatures relating functionalization of the carbon nanotubes in the modification of applications in nanocomposites and biological techniques can be seen there.
