Characterization of Chemically Synthesized Polyaniline-Zinc Oxide Nanocomposites

Author(s): Ganesh R. Yerawar

In the present paper, pure nanocrystalline zinc oxide compound was synthesized by chemical co-precipitation method. The composite of Polyaniline with nanosized Zinc Oxide was prepared by In-situ chemical oxidation polymerization method with ammonium per sulphate as an oxidant in aqueous hydrochloric acid under constant stirring at 0-4 0 C in presence of Nitrogen atmosphere. The d.c. electrical conductivities as a function of temperature (298-423 K) were measured by four probe technique. Electrical conductivity of composite with 20 % weight of Zinc Oxide is found to be more among all other composites and even than polyaniline. FTIR studies showed that there is strong interaction between polyaniline and nano sized Zinc Oxide particles.
