Abstract
Conducting poly(pyrrole) composite films were prepared by chemical polymerization in oxidant solutions by dipping poly(ethylene terephthalate) film (PET film) coated with poly(methyl methacrylate) (PMMA) and pyrrole monomers into a FeCl3 aqueous solution. The oxidation potential of this solution was controlled by adding a suitbable amount of FeCl2 to the solution before the reaction. By selecting appropriate polymerization conditions such as oxidation potential, temperature, time and FeCl3 concentration, highly conducting poly(pyrrole) composite films could be obtained. The SEM studies of the synthesized films indicated that polymerization conditions which lead to high reaction rates often yielded films of aggregated structures which have low conductivities.
