SYNTHESIS AND MAGNETIC PROPERTIES OF POLY (3, 4 - ETHYLENEDIOXYTHIOPHENE) (PEDOT)/FE3O4 COMPOSITES

Herein, we have successfully prepared Poly (3,4- ethylene dioxythiophene)/Fe3O4 composites by in-situ polymerization method . Initially, the as prepared magnetite nanoparticles were dispersed in the monomer using sonication process. Ferric chloride was used to initiate the polymerization reaction in aceto nitrile medium. The prepared nanocomposites were studied for its structural, microstructural, thermal, optical and magnetic properties.X-ray diffraction (XRD) study confirmed the formation of the PEDOT/Fe3O4 nanocomposites. SEM micrographs showed an increasing trend of the particle size with the increase in Fe3O4 content, which may be due to the effect of agglomeration at higher Fe3O4 content. The thermogravimetric analysis exhibited that the thermal stability of the nanocomposite was found to increase with the increase in Fe3O4 content. The saturation magnetization of the nanocomposites was found to be enhanced with the increase in Fe3O4 content. The results in this study indicated that the nanocomposite can be useful for information storage applications
