Electrical Conductivity of Polyaniline/NiZnO3 Composites: A Solid State Electrolyte

Abstract

In situ polymerization of aniline was carried out in the presence of nickel zinc oxide to synthesize polyaniline/NiZnO3 composites (PANI/NiZnO3) by chemical oxidation method. The composites have been synthesized with various compositions (10, 20, 30, 40 and 50 wt%) of nickel zinc oxides in PANI. From the infrared spectroscopy (FTIR) studies on polyaniline/NiZnO3 composites, the peak at 1140 cm(-1) is considered to be the measure of the degree of electron delocalization. The surface morphology of these composites was studied with the scanning electron micrograph (SEM). The dc conductivity was studied in the temperature range from 40-160 degrees C and supports the one-dimensional variable range hopping (1DVRH) model proposed by Mott. The results obtained for these composites are of scientific and technological interest.
