Electrochemical deposition and properties of polypyrrole films doped with calcion ligands Original Research Article

The properties of polypyrrole (PPy) film doped with calcion (calcichrome) in the process of electrochemical polymerization from aqueous solutions are presented. The properties of the films were inspected using different electrochemical methods, analysis by energy dispersive X-ray analysis and X-ray diffraction. Since the calcion ligands introduced to the PPy film retain the metal-complexing properties known from the aqueous solutions, it is possible to design calcium-sensitive sensors with an anticipated open-circuit response.
