Large-strain electroactive polymer bending actuators may consist of two conductive polymer layers electropolymerized on opposing faces of a porous membrane core that facilitates ion migration and electrolyte storage. Although several studies have been devoted to the conditions of the polymerization process, far less effort has been devoted to the systematic selection of the core material and the impact of the core's cellular morphology on the resulting actuation characteristics. This study introduces our initial work towards elucidating the relationship between the material properties of the porous core and the underlying actuation mechanism by reviewing how the physical characteristics of the membrane core are intrinsically captured by existing conductive polymer actuator models. The electromechanical response of polypyrrole trilayer actuators having poly(vinylidene fluoride) and Nylon cores is also explored.
