One of the rapidly developing frontiers in research is focused on the design of 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. Our research explores how polymer structure, counterion species, and film morphology affects the electromechanical response of ionic block copolymers when exposed to external electric fields using neutron reflectometry. The study proposed here focuses on understanding how these factors drive the electrostatic and mechanical stresses that result in material deformation.
