Hybrid conducting films, obtained by modification of poly(3,4-ethylenedioxytiophene) doped with Fe(CN)6 4-/3- ions by multicyclic polarization in aqueous FeCl3, NiCl2, and CoCl2 electrolytes, were examined by Energy Dispersive X-ray (EDX) and Micro-Raman measurements. EDX analysis allows to propose composition of metal hexacyanoferate (Mehcf) obtained inside polymer matrix as follows: Fe4[Fe(CN)6]3, Co3[Fe(CN)6]2, NiFe[Fe(CN)6] for materials modified in FeC3, CoCl2 and NiCl2 aqueous electrolytes respectively. Micro-Raman measurements show that the signal from CN is hindered for hybrid systems in comparison with inorganic Mehcf. Stoichiometry of inorganic part of the hybrid materials has been established by means of EDX measurements.
