Abstract
Polypyrrole-In2O3 nanocomposites have been synthesized by using in-situ chemical reaction method. The Polypyrrole nanocomposite were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffractometer (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), differential scanning calorimetry (DSC) techniques and the conductivity measurement were carried out at different temperature and frequency using two probe methods. The FTIR results confirmed the formation of chemical complexity of Polypyrrole and Polypyrrole/In2O3 nanocomposite and the structural phase change in the Polypyrrole nanocomposite was observed in XRD studies. The DSC results reveal enhanced thermal stability with respect to increased In2O3 nano concentration. The SEM image shows a substantial change in morphology after incorporating nano In2O3 and the presence of nanoparticle in composites was noticed in TEM images. The dielectric parameters are found enhanced with temperature and nano concentration. The AC and DC electrical conductivity increases with increasing nano concentration in polymer nanocomposites and achieved maximum conductivity for 50wt%. The magnetic properties of Polypyrrole/In2O3 nanocomposite are larger at 50wt% and decreases with decreasing the concentration of In2O3 nanoparticles in PPy composite. The observed results are suggesting that Polypyrrole–In2O3 nanocomposite material is a prominent candidate for LPG sensing and potential applications.
