Finite volume effects of ions in ionic membranes

Abstract

Ionic membranes are selectively permeable membranes that are widely used in electrochemical cells, as well as in electroactive polymer-based actuators and sensors. They consist of a polymer with fixed charges, saturated by a solution of ions of opposite charge. Here, we theoretically demonstrate that, by including the volume of ions in the model of the mechanics and electrochemistry of ionic membranes, solvent can migrate in the direction opposite to that expected from osmosis. This phenomenon occurs at the nanometer scales, paving the way for new concentration and dilution techniques in nanoscale devices.
