Abstract :

Polypyrrole is prepared by chemical oxidation method using ammonium per sulphate [(NH4)2S2O8] as oxidant. Copper ferrite is prepared by co-precipitation method. Polypyrrole-copper ferrite nanocomposite is prepared by in situ polymerization of pyrrole in aqueous solution with three different concentrations such as 75% pyrrole & 25% copper ferrite (CS I), 50% pyrrole & 50% copper ferrite (CS II) and 25% pyrrole & 75% copper ferrite(CS III). The prepared samples are characterized by XRD, UV-Vis spectroscopy, FT-IR, SEM and A.C. impedance spectroscopy methods. SEM studies reveal that the polypyrrole has a quasi-spherical structure. The grain sizes of the samples are found out using Debye-Scherrer formula. The strain in the prepared samples is found out using Williamson-Hall plot. Fourier Transform Infra Red spectroscopy studies results confirm the formation of polypyrrole and copper ferrite Ultra violet spectroscopy studies show that the optical band gap of the material changes on addition of copper ferrite.
