Synthesis and Structural studies of lightweight CNT/Cu composites: An overview

Abstract

Abstract An overview on structural and electrical properties of carbon nanotubes (CNTs) and Copper (Cu) based composite is presented keeping in mind their applications today and in the near future. CNTs are emerging as the most promising conducting wires in interconnection technology due to their higher electrical conductivity and extraordinary current-carrying capacity. In this work, we have found that, metal sputtering technique proved useful for the deposition of Cu nanoparticles on the surface of nanotubes. The structural and morphological studies of Cu deposited nanotubes were investigated by Raman spectroscopy and scanning electron microscopy (SEM). It was found that, the presence of prominent Raman bands in Cu deposited nanotubes is clear indication of the nanocompoites formation without destruction of carbon tubular structure. CNTs/Cu composites showed high conductivity and ampacity, making it uniquely suited for applications in microscale electronics and inverters.
