Synthesis and the physical properties of MnZn ferrite and NiMnZn ferrite–polyaniline nanocomposite particles
Abstract
We present a novel approach to synthesize MnZnferrite (MZF)–NiMnZnferrite(NiMZF)–Polyaniline (PANI) particles, where MnZnferrite is the magnetic core, and PANI is the conducting layer. The commercial ferrite and Ni–ferrite particles are primarily used, and the PANI–ferrite particles with a hybrid structure are synthesized via an oxidative electrochemical polymerization of aniline in an aqueous solution, which contains well-dispersed ferrite particles. The influence of ferrite content with respect to the electrical and ferromagnetic properties of the composite has been investigated by Electrochemical Impedance Spectroscopy (EIS) and DC field-cooled, zero-field cooled susceptibilities and M–H loop measurements. The origin of their electrical and ferromagnetic properties is also discussed based on structural characterizations including Fourier Transform Infrared (FT-IR) spectroscopy and X-Ray Diffraction (XRD).
