Bifunctionality of chemical sensors based on the conducting polymer polypyrrole.
Responses of polypyrrole based ion-selective chloride electrode were investigated in chloride and redox media. Bifunctional character of the potentiometric response of the polypyrrole films doped with chloride ions was observed being sensitive both to chloride ions and to the redox potential of the solution, however the redox response seems to predominate.
