STRUCTURE, SYNTHESIS, APPLICATIONS AND COMPARISON OF SINGLE WALLED AND MULTI WALLED CARBON NANOTUBES
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 4, Issue 7
Abstract
Carbon nanotubes (CNTs) are allotropes of carbon. These cylindrical carbon molecules have interesting properties that make them potentially useful in many applications in nanotechnology, electronics, optics and other fields of materials science, as well as potential uses in architectural fields. They exhibit extraordinary strength and unique electrical properties, and are efficient conductors of heat. Their final usage, however, may be limited by their potential toxicity. Various methods have been thoroughly investigated for the growth of C N Ts. The best and the most commonly used method is Chemical Vapour Deposition (CVD ). The various techniques include Reaction Chamber heating, Plasma Enhanced CV D, Hot filament CVD , Microwave CVD. The structural uniformity of carbon nanotubes produced by plasma enhanced Chemical Vapour Deposition gives uniform height and diameter. This paper discusses about all the methods listed above and detail comparisons are listed. We have simulated the single layer and multi layer Carbon nanotube using nano explorer tool and enumerated its properties for various applications like power storage and medical applications. The simulated properties of CNT would be used for energy storage purpose as well for transmission of electrical energy. Though it is known that CNT’s have high aspect ratio, Young’s modulus over one terra Pascal, Tensile strength of 200 Gigapascal, these properties never remain the same for all the CNT’S. It depend s upon the method of preparation, catalyst used etc. So the properties of C N T are studied for specific conditions. Here it is proposed CNT can be modeled for particularly electrical storage purpose.
