ABSTRACT:
To improve adhesive properties between an electrically conductive polymer membrane and a solid electrolyte membrane to each other, and thus to ensure the operation of an electrically conductive polymer actuator which effects a bending motion is aimed.The bendable electrically conductive polymer actuator of the present invention is an electrically conductive polymer actuator having a laminate structure of: a first organic polymer including at least one or more of a vinylidene fluoride/hexafluoropropylene copolymer, polyvinylidene fluoride, a perfluorosulfonic acid/PTFE copolymer, polymethyl methacrylate, polyethylene oxide, and polyacrylonitrile; a solid electrolyte membrane including a mixture with an ionic liquid; and an electrically conductive polymer membrane including a mixture of polyethylenedioxythiophene and polystyrene sulfonic acid on at least one face of the solid electrolyte membrane, in which a second organic polymer including a vinylidene fluoride/hexafluoropropylene copolymer is embedded in the electrically conductive polymer membrane surface in the state being dispersed.
