In this work, novel nanocomposites (NCs) were fabricated via in situ-chemical oxidative polymerization process. For the purpose of examining their physical and chemical properties, the synthesized samples were examined utilizing a variety of analytical techniques. XRD, TEM, SEM, electrical and dielectric studies confirm the presence of copolymer P(Py-co-OT) and reveal that MFe2O4@P(Py-co-OT)NCs exhibited a core–shell structure. The Poly (Pyrrole-co-o-toluidine) possessed the highest activation energy and the lowest conductivity. Moreover, the incorporation of MFe2O4 into copolymer enhances the conductivity. Impedance analysis emphasizes the contribution of grain boundaries on transport properties. A relationship between the polarization effect and the dielectric behavior was found. An enhancement on the dielectric constant εʹ and the dielectric loss ε″ was noticed with the embedding of spinel ferrites into copolymer. Results obtained suggest that this binary material has a promise for use in energy conversion applications. [ABSTRACT FROM AUTHOR] |
