This paper discusses about the survey on the various magazines, conference papers and journals for understanding the properties of enamelled copper wires mixed with nano fillers, fundamental methods for synthesis and characterization of carbon nanotubes. From all these papers, it was noted that the research work carried out in an enamelled copper wires filled with nano fillers has shown better results. It was also recorded that the research work was carried mostly with single metal catalysts and very little amount of research work has been carried out on the synthesis of carbon nanotubes using bimetallic catalysts.
