Abstract

By adding bismuth oxide to the polymerization mixture of aniline hydrochloride and ammonium persulphate using chemical oxidation polymerization, conducting polyaniline/bismuth oxide (PANI/Bi2O3) composite was prepared. The effect of adding Bismuth oxide powder, during polymerization process, on the time and temperature of reaction has been studied. The structural and morphology of the composite were distinguished by X-ray diffraction pattern (XRD) and scanning electron microscope (SEM) micrographs. The dc electrical transport property of PANI/Bi2O3 composites has been investigated within temperature range 30-2000C and ac electrical property of PANI/Bi2O3 composites has been studied as function of frequency. The gas-sensing performance of the PANI/Bi2O3 composites was studied at room temperature for Liquified Petroleum Gas (LPG). The change in resistance of the composites as function of time towards LPG was investigated.
