Patent ID: 7733000

Claim:
A bendable electrically conductive polymer actuator comprising a pair of electrodes, and a laminate structure sandwiched between the pair of electrodes, wherein: the laminate structure comprises a solid electrolyte membrane constituted with a mixture of an ionic liquid and a first organic polymer comprising 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 polyethylenedioxythiophene (PEDOT) and polystyrene sulfonic acid (PSS), and formed on at least one face of the solid electrolyte membrane; a second organic polymer constituted with a vinylidene fluoride/hexafluoropropylene copolymer [P(VDF/HFP)] is embedded in the state being dispersed in the electrically conductive polymer membrane surface; and the solid electrolyte membrane is in contact with the electrically conductive polymer membrane surface in which the second organic polymer is embedded in the state being dispersed.
