Abstract

Abstract: The negative dielectric constant has been attracting attention of many researchers due to its significant applications viz. superconductor, in this present work, carbon nano materials (CNM) have been synthesized from plant fiber (cotton) for the negative dielectric constant ‘meta-materials’ study. The synthesized CNM was decorated with copper nano particles confirmed with the XRD. Whereas obtained material is a mixture of amorphous and graphitic carbon, confirmed by Raman spectroscopy. SEM and TEM images of the carbon filaments indicates that the CNF have 30 to 50 nm thicknesses with 357.3 nm diameters while decorated copper nano particles are in between 50-70 nm range in size respectively.
