Ion gels for ionic polymer actuators

Masayoshi Watanabe, Satoru Imaizumi, Tomohiro Yasuda, Hisashi Kokubo

    Abstract

    Ionic polymer actuators are driven by the migration or diffusion of ions and generally exhibit significant deformation (i.e., bending) under low-voltage (<5 V) applications. However, the durability of conventional ionic polymer actuators decreases under open atmosphere owing to the evaporation of solvents, which are essential for the movement of ions, from the actuators. In order to overcome this drawback, ionic polymer actuators that can be operated under open atmosphere and even under vacuum are being developed using ionic liquids (ILs). Combining macromolecules with ILs as additives can result in highly ion-conducting polymer electrolytes (ion gels) suitable for applications in ionic polymer actuators. However, the contribution of polymeric materials to the high performance of IL-based polymer actuators is yet to be elucidated. In this chapter, IL-based polymer electrolytes comprising block copolymers and polyimides are demonstrated to enable easily processable ionic polymer actuators with high performance and durability. The displacement response is also analyzed using our proposed displacement model.
