Abstract

Conducting polymers are the materials with electronic properties in the range of semiconducting to conducting region. Incorporating metal oxide in polymer matrix increases the conductivity of polymers. Vanadium pentoxide (V2O5), a classic metal oxide as well as a semiconductor doped in polyaniline (PANI) matrixhad significant changes within the composite. In this study we compared the properties of V2O5/PANI composite and Polyaniline synthesized by in situ-chemical oxidation polymerization method using ammonium persulphate [(NH4)2S2O8] as an oxidant. V2O5 is added in different weight percentage (10, 20 & 30%). Further, they are characterized by X-ray diffraction (XRD) analysis, fourier transform infra (FTIR) spectroscopy, UV-Vis spectroscopy and scanning electron microscopy (SEM). IV graph of PANI and V2O5/PANI have been taken out. It is ascertained that, incorporation of V2O5 into PANI matrix will influence the structural, morphological, optical and electrical properties in a visible scale.
