Polypyrrole (PPy)/Yttrium Iron oxide (YIG) nanocomposite was synthesized by the chemical oxidation polymerization method. Yttrium iron oxide is also known as iron yttrium oxide or yttrium iron garnet denoted as YIG (Y3Fe5O12). YIG is a familiar material among the rare earth garnets and is also commonly used in electronic devices. Fourier transform infrared (FT-IR) spectroscopy analysis reveals the strong interaction between PPy and YIG nanoparticles. The crystal structure for the PPy and PPy nanocomposites is observed by X-ray Diffraction (XRD) and the average crystalline size calculated by Scherrer's formula for PPy/n-YIG is 27.47 nm. Surface morphology of the samples identified by scanning electron microscopy. Optical properties were studied by UV–Vis spectroscopy. From the 2-probe method, AC electrical conductivity for n-YIGPPy is found to be 1.05 × 10−5 S/cm, higher than that of the polypyrrole. The electrochemical performance of PPy and YIG/PPy nanocomposites was observed by cyclic voltammetry (CV). The combination of optical, electrical properties of YIG/PPy nanocomposites suits supercapacitor applications. [ABSTRACT FROM AUTHOR] |
