One of the rapidly developing frontiers in research is focused on the rational design of polymeric materials that have targeted functionalities and tunable responses to external stimuli. A chief obstacle to achieving this capability is the lack of a fundamental understanding of how chemical structure and morphology give rise to macromolecular properties. Considering this, the research proposed here aims to investigate how polymer structure and counterion identity affects the electromechanical response of materials when exposed to external electric fields. Our previous results have confirmed that neutron reflectometry is an ideal tool for monitoring the motion of both the polymer backbone and counterions. This proposal builds on those findings and will focus on understanding how film rigidity and counter-anion size restricts or enhances the system response to an applied electric field.
