Abstract
Polyaniline (PANI) composites doped with Vanadium pentoxide (V2O5) of different weight percentage using dodecylbenzene sulfonic acid (DBSA) as surfactant was prepared by in-situ chemical oxidation reaction method. Here ammonium persulphate was used as an oxidizing agent. The formation of composite (PANI/DBSA/V2O5) was confirmed with the help of analytical studies like scanning electron microscopy (SEM) and UV/Vis spectroscopy. SEM images show a substantial change in PANI morphology after incorporation of vanadium pentoxide. The optical characterizations by UV-Vis absorption spectroscopy show the increased absorption with addition of V2O5. The electrical conductivity has been studied in the frequency range of 20 Hz to 1MHz and it is found that PANI/DBSA:2%(V2O5) shows high electrical conductivity compared to pure PANI and other composites. It is observed that the dielectric constant and dielectric loss increase with concentration of V2O5. PANI/DBSA/V2O5 composites are most promising material for many electrical and potential applications. This semiconducting polymer combination of PANI and Vanadium pentoxide (V2O5) which produce hybrid material, behaves as semiconductor at low temperatures; this behavior is predicted by results of dielectric properties studied.
