Energy Dispersive X-Ray Analysis and Micro-Raman Studies of Poly (3,4-Ethylenedioxythiophene) Modified by Metal HexacyanoferratesHybrid conducting films, obtained by modification of poly(3,4-ethylenedioxytiophene) doped with Fe(CN)64-/3-ions by multi-cyclic polarization in aqueous FeCl3, NiCl2, and CoCl2electrolytes, 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 FeCl3, CoCl2and NiCl2aqueous 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. |
