Abstract
An electrically conductive polymer actuator having a laminated structure including: a solid electrolyte membrane constituted with a mixture of an ionic liquid, and an organic polymer that contains at least one or more of a vinylidene fluoride/hexafluoropropylene copolymer [P(VDF/HFP)], polyvinylidene fluoride (PVDF), a perfluorosulfonic acid/PTFE copolymer, polymethyl methacrylate (PMMA), polyethylene oxide (PEO) and polyacrylonitrile (PAN); and an electrically conductive polymer membrane constituted with a mixture of polystyrene sulfonic acid (PSS) and polyethylenedioxythiophene (PEDOT) on at least one face of the solid electrolyte membrane, characterized in that polyethylene glycol is included in the electrically conductive polymer membrane.
