Polyanilines, synthesis electrode materials

The synthesis of polyaniline and copolymers of aniline with o-nitroaniline is aimed at obtaining an electroactive material. This material can be used, for example, as an electrode in conjunction with the magnesium electrode to construct chemical power sources. The polymers were prepared by oxidation of aniline or its mixture with nitroaniline ammonium persulfate in aqueous hydrochloric... 

The electrochemical stability of PAn film at higher potentials is essential for its use as an electrochromic material and as a catalytic electrode. Similarly, soluble polyaniline is also required for many applications to facilitate post-synthesis processing. Electrochemical polymerization can be carried out by 0.1 M monomer in 1 M of aqueous solution of aromatic sulphonic acid. Prior to polymerization, the solution should be deoxygenated by passing argon gas for 30 minutes.
