Ionomer thin-films by electrochemical synthesis: bipolar and ampholytic membranes.

Sooner or layer: Electrochemical deposition is a particularly elegant and effective route for the preparation of thin and conformal solid polymer electrolyte layers. In this work, we explore the electrochemical synthesis of amphoteric ion-exchange membranes by co-deposition of two precursors with acidic and basic groups. The sequential deposition gives bipolar layers with an ionically blocking interface. These ionomer films may be used for various applications, such as pH-sensitive microactuators, ionic diodes or catalytic layers for water splitting.
