Novel Synthesis of Polyaniline Using Iron(III) Catalyst and Ozone

Polymerization of aniline using iron(III) and ozone as a catalyst and an oxidant, respectively, provided polyaniline with an emeraldine form based on IR and UV–vis spectroscopic data, although influence of the reaction temperature upon the molecular weight of the polyaniline was different from the case of ammonium peroxodisulfate. Preliminary results of experiments have revealed that polyaniline is produced catalytically in terms of iron(III). Morphology of polyaniline produced significantly influenced electrical conductivity of the polyaniline pellet.
