摘要

In this work, we present an alternative route to prepare silver hexacyanoferrate(II)/polyaniline (PANI) composites thin films and compare these results with the conventional chemical synthetic route, and with the electrochemical process deposited in platinum electrodes. Differently from the electrochemical method, used to synthesize the conducting polymer film on a electrode surface, this new chemical route make use of dialysis membrane as a solid support to synthesize the silver hexacyanoferrate(III) compound, and subsequently uses this composite membrane as oxidant to polymerize the aniline monomer. The spectroscopic (UV-Vis. and IR region) and electrochemical characterization (cyclic voltammetry) indicate that the polymeric composite remains optically active and conductive. The X-ray analysis show that the composite has an amorphous and a crystalline structure assigned to the conducting polymer and to the Ag-4[Fe-II(CN)(6)] structure respectively.
