INTRODUCTION Sumio Iijima, a Japanese electron microscopy expert, first discovered carbon nanotubes (CNTs) during carbon arc discharge method in 1991. Later, these were named as carbon nanotubes (CNTs) which are very long and extremely thin cylinders of carbon [1]. The basic structural element of carbon nanotubes is graphene which is a sp 2 planar sheet (bonded) of carbon atoms in which these carbon atoms are densely packed as shown in Fig. 1. Carbon nanotubes are formed when this graphene sheet is rolled in the form of cylinder. Length of the carbon
