CHAPTER 5: Membrane Composition-Dependent Electrochemical Properties

During electrochemical reactions, the polymer:counterion ratio changes in films of conducting polymers in a reversible way through several orders of magnitude. Any property of the material being a function of the material composition (a composition-dependent property) will also change in a reversible way inside a large range of values. The composition-dependent properties include the electronic conductivity, volume, color, stored charge, ionic storage, transversal ionic conductivity, material potential, wettability, ionic delivery and the electro-chemo-conformational energetic memory, which may be described by some composition-dependent equations. These composition-dependent properties mimic biological functions and are discussed in this chapter.
