Application of electroactive materials composed of conducting polymers andpolynuclear inorganic compounds

Polyaniline can serve as a robust, conductive, matrix for cyanometallate re dox centers such as nickel(H) hexacyanoferrate(III,II) and iron(III,II) hex acyanoferrate(II,III) (i.e., Prussian Blue). The respective hybrid organic/ inorganic films can be grown on various electrode substrates including glas sy carbon, platinum and stainless steel. Upon incorporation of metal hexacy naferrate into polyaniline, the electrochemical stability of the resulting composite film is increased. A multilayered film consisting of polyaniline and nickel hexacyanoferrate on carbon substrates shows high dynamics of cha rge propagation, and it is capable of accumulating large quantities of char ge. The system is of interest to the construction of positive electrodes in Faradaic (redox) supercapacitors. ne hybrid polyaniline/Prussian Blue film , while deposited on stainless steel, shows protective properties against p itting corrosion in chloride containing solutions.
