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.
