Polypyrrole and its composites were prepared chemically using FeCl3 as an oxidant in aqueous and non-aqueous media. The effect of various solutions such as water, ethylacetate, acetonitrile, methylacetate, methanol, ethylmethylketone and surface active agents, poly (ethylene glycol) and poly (vinyl acetate) on the properties of product were studied. The electrically conducting polymer and its composites have been characterized by Scanning Electron Microscopy (SEM), Fourier Transform Infrared (FTIR) and proton nuclear magnetic resonance (1H NMR) spectroscopy. The results indicate that the morphology, conductivity and structure of products are dependent on the type of solution and additive.
