In recent years, the development of efficient green chemistry methods for synthesis of nano particles has become a major focus of researchers. In this work polyaniline (PANI) -cobalt ferrite nano composite is prepared using green solvent tamarind extract by oxidative chemical polymerization of aniline in presence of cobalt ferrite. Because of their unique electromagnetic properties, these composite nanoparticles have been increasingly employed in magnetic resonance imaging (MRI), targeted drug delivery and therapy. The structural characterization of the composite particles is done by XRD and IR and surface morphology by SEM. The magnetic properties of the samples prepared by varying the cobalt ferrite content in PANI are studied by VSM analysis and ac conductivity of the samples were calculated using the dielectric parameters measured using a dielectric cell.
