چکیده مقاله :

A new method for the synthesis of water soluble Polyaniline (PANi) using Hemin Chloride (H.C) in the presence of hydrogen peroxide (H.P) is presented. Hemin chloride is an effective catalyst for the oxidative polymerization of aniline in the presence of hydrogen peroxide at room temperature. The UV- Vis absorption spectra of the product show a distinct absorption peak at 430 nm in pH 4.0 buffer solution, indicating the formation of Polyaniline. A new mechanism for polymerization of aniline in the presence of H.0 and H.P is also presented.
