Patent ID: 7638930

Claim:
A bendable electrically conductive polymer actuator comprising: a pair of electrodes, and a laminating structure sandwiched between the pair of electrodes, wherein the laminating structure comprises: a solid electrolyte membrane constituted with a mixture including an ionic liquid, and a first 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 which is formed on the solid electrolyte membrane, and which is constituted with a mixture of polyethylenedioxythiophene (PEDOT) and polystyrene sulfonic acid (PSS), and wherein a second organic polymer constituted with polyvinylphenol (PVP) is embedded in the state being dispersed, in the electrically conductive polymer membrane surface, and the solid electrolyte membrane is in contact with the face of the electrically conductive polymer membrane surface in which the second organic polymer is embedded in the state being dispersed.
