Abstract

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.
