Nanoscience and nanotechnology as innovative tool is changing our way of life.For the last 15 years,carbon nanotubes have attracted a great interest from academy and industry because they exhibited excellent physical and chemical properties due to their intrinsic nano-sized one-dimensional nature at the atomic level.It is noteworthy that carbon nanotubes are being used in a variety of commercial products.Carbon nanotubes are commercially available in a large quantity (1,000 ton/year) because the cost-effective synthetic technique for producing them in an industrial scale has been established [1, 2].
