POLYMER ACTUATOR

摘要

A polymer actuator comprising an ion exchange resin molding and, superimposed on the surface thereof, a metal electrode, wherein the surface of the polymer actuator is continuously provided with a coating layer of ion exchange resin or thermoplastic urethane rubber of 200% flexibility. Thus, there is provided a polymer actuator of excellent durability wherein not only can the strength decrease of the ion exchange resin molding be prevented but also the electrode deterioration can be inhibited even when curving or deformation of the polymer actuator is continuously or repeatedly carried out without detriment to the curving or deformation response of the polymer actuator.
