This proposal concerns the characterisation of buried polymer/polymer interfaces within the electrochemically controlled environment of an electroactive bilayer. The dependence of polymer/polymer interfacial structure on polymer redox (charge) states and its evolution with time and redox cycling will be investigated. In this context, the nature of this interface governs whether the 2-component polymer system shows the uni-directional charge transfer characteristics of an ideal bilayer and determines the switching rate (regardless of charge transport or kinetic control). In situ neutron reflectivity measurements will be used to determine the equilibrium (long time scale) spatial distribution of the two polymer components perpendicular to the electrode surface. Contrast variation experiments will be used to selectively highlight solvent, inner film and outer film components. Ellipsometric measurements will be used to investigate transient (short time scale) processes. These complementary methods (appropriately supported by electrochemical quartz crystal microbalance and spectorelectro chemical measurements) will facilitate separation of mobile species transfers and slow polymer relaxation processes. The longer term objective is to develop a general methodology for studying the structures of buried interfaces which commonly occur outside the electrochemical context.
