In the quest for such membranes conducting electroactive polymers provide several unique capabilities. Conducting polymer membranes such as polypyrroles (1, 2) or polyanilines (3) can be prepared by electropolymerisation and deposition of the monomer or by solvent casting of the polymer. 

The type, concentration, and mobility of ions in polymers define the membrane properties of these polymers. Due to the importance of ion transport processes associated with the oxidation/reduction of the considered electroactive polymers, membrane properties are a subject of central importance for a quantitative understanding of their electrochemical behavior. The discussion of this subject constitutes the essential part of Chapter 3. 

To discuss polymer membrane properties systematically, we first considered ions partioned into nonionic and ionic polymers from a general point of view. Then we analyze the membrane state of a polymer film on an electrode. Finally the mixed conductor properties of electroactive polymer films are discussed.
