The fabrication of finite arrangement with nanoscale materials is key to current technology and selfassembly and self-organization is considered an efficient and cost-effective and so a preferred process for building ordered structure of nano particles. Carbon nanotubes are
very interesting material for its properties and molecular structures. Carbon Nanotubes (CNT) can assemble in different morphologies depending on its physical synthesis method. The different morphologies of CNT are coiled CNTs, CNT junctions and toroidal CNTs. Thin polymer film < 100 nm also undergoes self-organization resulting in formation of arrays of droplets. These spontaneously formed ordered patterns or structures on the surface has wide range of technological applications. The retraction of fluid from the surface that it was supposed to cover leads to the phenomenon of dewetting causing the arrangement of droplets which act as a template for the self-assembly of the carbon nanotubes.
