Silver doped Nanocomposites ofpolypyrrole were successfully synthesized via in situ chemical oxidation polymerization of pyrrole. Ammonium Peroxodisulphate and Silver Nitrate were used as an oxidization agent and dopant, respectively. The molar ratio of monomer unit to oxidization agent and dopant was 1:1:1. The PPy-Ag Nanocomposites were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), and UVVisible spectroscopy. The electrical conductivity of chemically prepared polypyrrole in aqueous solution was found to be strongly dependent on the doping and oxidant used. It is probable apply for sensor and battery applications. Formation mechanism of the Ag/polypyrrole conducting polymer Nanocomposites is proposed.
