Problems solved by technology

[0005] An actuator that bends the gel with an electric field has a problem of increasing power consumption because the stress generated is small, and the flexibility cannot be maintained if the electric field is not continuously applied.
In addition, for actuators using dielectric elastomer films, high voltages of hundreds to thousands of volts need to be applied for deformation. In the case of home robots, there is a risk of electric shock due to excessive voltage. sexual problems

Embodiment 1

[0076] [Fabrication of a conductive polymer film in which a second organic polymer is embedded in a dispersed state]

[0077] A predetermined amount of PEDOT mixed with 5% by weight of dimethyl sulfoxide (DMSO) and 0.5% by weight of polyvinylphenol (PVP) and PSS was added dropwise to the glass slide treated with oxygen plasma after cleaning with acetone. An aqueous dispersion of the mixture (manufactured by Starck, trade name BAYTRON PH500). Since the specific gravity of PVP is smaller than that of the aqueous dispersion of a mixture of PEDOT and PSS, PVP emerges on the upper part of the mixed liquid. Then, the solvent was evaporated by natural drying at room temperature, and a conductive polymer film in which PVP was embedded in a dispersed state was formed on the slide glass. Finally, using a razor, peel off the conductive polymer film from the glass slide. The average thickness of the obtained conductive polymer film was 19 μm, and the conductivity measured by the four-pr...

Embodiment 2

[0090] [Fabrication of a conductive polymer film in which a second organic polymer is embedded in a dispersed state]

[0091] On the glass slide treated with oxygen plasma after cleaning with acetone, a predetermined amount of an aqueous dispersion of a mixture of PEDOT and PSS mixed with 5% by weight of N-methylpyrrolidone (NMP) (manufactured by Starck, commercialized) was dropped. named BAYTRON PH500). Before the film was dried, 0.1% by weight of polyvinylphenol (PVP) relative to the aqueous dispersion of the mixture of PEDOT and PSS was spread on the surface. Then, the solvent was evaporated by natural drying at room temperature, and a conductive polymer film in which PVP was buried in a dispersed state was formed on the silicon substrate.

[0092] Finally, the silicon substrate was immersed in a 50% by volume potassium hydroxide aqueous solution, and the conductive polymer film was peeled off from the substrate. The average thickness of the obtained conductive polymer fi...

Embodiment 3

[0104] Except that 0.05 wt%, 0.1 wt%, 1 wt%, and 5 wt% of polyvinylphenol (PVP) were mixed, the same procedure as in Example 1 was carried out to obtain a curved conductive polymer actuator. When a voltage of ±1.0 V was applied to these actuators, no peeling occurred at the interface between the electrolyte ion gel and the conductive polymer film, and a bending operation in response to the applied voltage was performed. As the amount of displacement, a square wave of 1 Hz was used, and the average amount of displacement for the first 10 times was 0.40 mm or more. Even when these actuators are driven continuously for a long period of time as in the first and second examples, they can stably perform the bending operation. On the other hand, the dispersion solution in which 5% by weight of polyvinylphenol (PVP) was dissolved was very brittle, and it was not possible to obtain a curved conductive polymer actuator in the same manner as in Example 1. (table 3)

Abstract

The objective of the invention is 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 laminating structure of: a first organic polymer including at least one or more of a vinylidene fluoride / hexafluoropropylene copolymer, polyvinylidene fluoride, a perfluorosulfonic acid / polytetrafluoroethylene 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 polyvinylphenol is embedded in the electrically conductive polymer membrane surface in the state being dispersed.

Description

technical field [0001] The present invention relates to a conductive polymer actuator applicable to home robots and a method for manufacturing the same. In particular, it relates to an actuator utilizing an electrochemical reaction and a method of manufacturing the same. Background technique [0002] In recent years, in the fields of medical and home robots, the need for small, lightweight, and flexible actuators has been increasing. The reason is that robots that are expected to help with housework or work in homes or offices, hospitals, etc., and to help care for the elderly or disabled people are active around people, and the actuators for moving the robots require human resources. The properties of the muscle (for example, the safety that will not be injured even if touched, the softness that will not feel pain even if bumped, etc.). [0003] As small and lightweight actuators, electrostatic attraction type, piezoelectric type, ultrasonic type, and shape memory alloy t...
