Synthesis and Characterization of Composite Polypyrrole-Vanadium Oxide (PPy/V2O5)

Abstract

Conducting polymer attracts broad attention to researchers due to their good properties such as high environmental friendly, thermal and chemical stability as well as high conductivity. There are widely use in potential components of optical storage, sensors, batteries, supercapacitor and so on. In this work, polypyrrole was synthesized using chemical oxidation polymerization technique which involves FeCl 3 and nanoparticle vanadium oxide (V 2 O 5). The composite PPy/V 2 O 5 has been synthesized under 0 °C with variation weight percentage of nanoparticle V 2 O 5 from 10% to 50% with increment of 10%. The properties of composites have been characterized by x-ray diffraction (XRD) and Field Scanning Electron Microscopy (FESEM). The ac conductivity has been carried out under frequency range of 100 Hz to 1 MHz over temperature 273 K to 393 K. It is observed that the ac conductivity of composite increass steeply after frequency of 105 Hz. The composite PPy-V 2 O 5 has shown the larger d-spacing compared to pure PPy and FESEM shows the spongy-like graph of pure polypyrrole than composite PPy/V 2 O 5 .
