Structural and Optical Properties of Sr2Co1.9Bi0.1Fe11.9 Zn0.1O22/PANI Nanocomposites

Abstract

Recently Hexaferrites have attracted the attention of researchers due to its wide applications such as permanent magnets, magnetic recording media, microwave applications and Wireless telecommunication system. Sr2Co1.9Bi0.1Fe11.9 Zn0.1O22 was successfully synthesized using sol-gel method while oxidative polymerization was employed to synthesized polyaniline (PANI). The precursor material is pre sintered at 500C for 5 hours and sintered at 1000C for 5 hours. The characteristics of the samples were defined by using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy and Ultraviolet visible spectrophotometer (UV-vis). XRD analysis confirms the spectral purity of the sample. FTIR analysis indicates the formation of y-type hexaferrites by the appearance of two prominent peaks at 400 and 600 cm-1. Raman spectra show the presence of Y-type hexaferrites and PANI by the appearance of prominent Raman shifts. The band gap of the prepared nanocomposites was evaluated using UV-vis spectroscopy.
