Abstract

In this article, we reported microwave assisted processing of vanadium oxide-polyaniline nanocomposite (PANI/V2O5). Firstly, polyaniline (PANI) is synthesized by oxidative polymerization method and vanadium pentoxide nanoparticles. In the second step, intercalation of PANI in V2O5 framework are carried out in the microwave at 80 ºC for 30 min in Teflon crucibles. The XRD exhibited a set of well-defined peak support the crystal nature of nanocomposites. FTIR studies of the composite supported the intercalation of PANI with V2O5. The peaks obtained by cyclic voltammetry shows marginal separation between anodic peaks at 3.6 and 3.7 V for polyaniline and shifted to the higher potential for PANI/V2O5 nanocomposite. Also, the electrical conductivity is found to be 10-6 S cm-1 for PANI and higher electrical conductivity, 10-4 S cm-1 for nanocomposites.
