Description

  The present invention relates to a conductive polymer actuator that can be applied to household robots and the like, and a method for manufacturing the same. In particular, the present invention relates to an actuator using an electrochemical reaction and a manufacturing method thereof.

  In recent years, there has been an increasing need for a small, lightweight, and flexible actuator in the medical and home robot fields. This is because actuators for operating robots that are expected to play an active role in the immediate vicinity such as housework support and work support at home, office, hospital, etc. This is because such a property (for example, safety that does not cause injury when touched or softness that does not hurt when bumped) is required.

  Electrostatic attractive type, piezoelectric type, ultrasonic type, and shape memory alloy type have already been put to practical use as small and lightweight actuators, but these use inorganic materials and their operating principles. Therefore, it cannot be a flexible actuator. Therefore, in recent years, various attempts have been actively made to realize a lightweight and flexible actuator by using an organic material such as a polymer.

  For example, a gel is bent by an electric field (Patent Document 1), a gel is deformed by applying a strong electric field between dielectric elastomer thin films (Non-Patent Document 1), and a conductive polymer is expanded and contracted by a redox reaction. (Patent Document 2) and the like.

  An actuator that bends the gel by an electric field has a problem that the generated stress is small and the bending property cannot be maintained unless the electric field is continuously applied, so that the power consumption increases. In addition, those using a dielectric elastomer thin film require a high voltage of several hundreds to several kilovolts for deformation, and when used for a home robot, the voltage is too high, and there is a risk of electric shock and the like. . On the other hand, conductive polymer actuators that use the expansion and contraction associated with oxidation and reduction of conductive polymers have a relatively simple structure, are easy to reduce in size and weight, are flexible, and can be driven at a low voltage of several volts. It has a feature that the generated stress is sufficiently strong.

  As shown in FIG. 2, the bending actuator using the expansion and contraction of a conductive polymer has a structure in which a conductive polymer film is laminated on at least one surface of a solid electrolyte film. In FIG. 2, 201 is an actuator element, 202a and 202b are conductive polymer films, 203 is a solid electrolyte film, and 204a and 204b are electrodes. When a conductive polymer film is laminated only on one side of the solid electrolyte membrane, a metal electrode thin film (counter electrode) is formed on the other side of the solid electrolyte membrane in order to apply a voltage. A metal electrode thin film may be formed on the conductive polymer film in order to apply a voltage. Then, the laminated film is bent by applying a predetermined voltage between the conductive polymer film and the counter electrode or between the conductive polymer films. The operating principle of bending is considered as follows. That is, the conductive polymer is oxidized and reduced by voltage application, and ions are taken into or taken out of the conductive polymer film accordingly. The volume of the conductive polymer film changes due to the entry and exit of the ions, and the actuator is bent because it is laminated with the solid electrolyte film that does not change in volume. For example, in the configuration shown in FIG. 2, when ions are taken into the upper conductive polymer film or ions are taken out from the lower conductive polymer film, the upper conductive film is turned downward. When ions are extracted from the conductive polymer film or ions are taken into the lower conductive polymer film, the film bends upward.

  Examples of the conductive polymer used for the actuator include polyaniline, polypyrrole, polythiophene, and derivatives thereof (Patent Document 2).

Conductive polymer actuators use ions in and out of the conductive polymer film as a result of the electrical oxidation and reduction of the conductive polymer as the principle of operation. An electrolyte is required, and in order to operate in air, a solid electrolyte having sufficient ionic conductivity at a temperature of about room temperature is required. In recent years, a material named ion gel has been created. This is at least one of polymers or monomers dispersed in the ionic liquid is gelled, a material holding an ionic liquid into a three-dimensional network structure of the gel has a softness, and at room temperature for 10 ^{- A value of 2} S / cm, which is 100 times or more that of a conventional polyether polymer solid electrolyte, has been achieved (Non-patent Document 2).

  In addition, Patent Document 3 is cited as a document that can be related to the present invention.

  Patent Document 3 discloses a polymer actuator device. 9 and its description include a control electrode A (reference numeral 203), an electrolytic displacement part A (reference numeral 201) made of a conductive polymer, an electrolyte part (reference numeral 202), and a high conductivity. A polymer actuator device comprising an electrolytic displacement part B (reference symbol: 201 ′) made of molecules and a control electrode B (reference symbol: 203 ′) is disclosed.

Furthermore, paragraph number 0077 of Patent Document 3 describes that polythiophene is preferable as the conductive polymer. Paragraph No. 0078 of Patent Document 3 discloses that a fluorine-based polymer such as polyvinylidene fluoride or a copolymer thereof is used as the polymer solid electrolyte. Furthermore, it is disclosed that sulfonic acid may be introduced into the basic skeleton.

  In conventional conductive polymer actuators, polyaniline, polypyrrole, polythiophene and their derivatives are used as conductive polymers, but these conductive polymer films and solid electrolyte films made of ion gel have mutual adhesiveness. Low. Therefore, when a bending type actuator is formed by stacking a conductive polymer film and a solid electrolyte film made of ion gel, there is a problem that the conductive polymer film and the solid electrolyte film made of ion gel are peeled off during the operation.

  An object of the present invention is to improve the adhesion between a solid electrolyte membrane made of a conductive polymer membrane and an ionic gel, and to realize a bent type conductive polymer actuator that does not deteriorate even when repeatedly operated. Furthermore, it aims at providing the manufacturing method for implement | achieving this actuator.

  The present invention relates to vinylidene fluoride / hexafluoropropylene copolymer [P (VDF / HFP)], polyvinylidene fluoride (PVDF), perfluorosulfonic acid / PTFE copolymer, polymethyl methacrylate (PMMA), polyethylene oxide ( PEO), polyacrylonitrile (PAN), a solid electrolyte membrane made of a mixture of an organic polymer containing at least one of polyacrylonitrile (PAN) and an ionic liquid, and at least one surface of the solid electrolyte membrane is polyethylenedioxythiophene (PEDOT) and polystyrene sulfonic acid (PSS). A conductive polymer actuator having a laminated structure with a conductive polymer film made of a mixture of (1), wherein the conductive polymer film contains polyvinylpyrrolidone. To do.

  In addition, the present invention provides a vinylidene fluoride / hexafluoropropylene copolymer [P (VDF / HFP)], polyvinylidene fluoride (PVDF), perfluorosulfonic acid / PTFE copolymer, polymethyl methacrylate (PMMA), poly A solid electrolyte membrane comprising a mixture of an organic polymer containing at least one of ethylene oxide (PEO) and polyacrylonitrile (PAN) and an ionic liquid; and at least one surface of the solid electrolyte membrane is polyethylenedioxythiophene (PEDOT) and polystyrenesulfonic acid A method of manufacturing a conductive polymer actuator having a laminated structure with a conductive polymer film made of a mixture of (PSS), the step of mixing polyvinylpyrrolidone in the conductive polymer film, and the solid electrolyte film The conductive polymer film on at least one side of It provides a method for producing a conductive polymer actuator characterized by comprising the step of laminating.

  According to the present invention, a bend-type conductive polymer actuator is realized in which the adhesion between the conductive polymer film and the solid electrolyte membrane made of ion gel is improved, and the characteristics are not deteriorated even when operated repeatedly.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a schematic cross-sectional view of an actuator according to an embodiment of the present invention. The actuator 101 is composed of a laminate of conductive polymer films 102a and 102b and a solid electrolyte film 103, and electrodes 105a and 105b are disposed so as to sandwich one end of the conductive polymer films 102a and 102b. By applying a voltage of several volts between the electrodes 105a and 105b, the actuator 101 bends with the portion sandwiched between the electrodes 105a and 105b as a fixed portion.

  The conductive polymer used in the present invention has a conjugated double bond, whereby π electrons spread throughout the polymer and contribute to electronic conductivity. Electrical conduction of conducting polymers is thought to occur when polarons and bipolarons generated by the interaction between oxidants doped in polymers and π electrons in the polymers become charge carriers. . In the present invention, polyaniline, polypyrrole, polythiophene, and derivatives thereof can be used as the conductive polymer. In particular, polyethylenedioxythiophene (PEDOT) is preferably included, and further, polyethylenedioxythiophene (PEDOT) and polystyrene are included. It is preferable to use a mixture of sulfonic acid (PSS). Polyethylenedioxythiophene (PEDOT) can chemically polymerize this monomer in advance, so that a conductive polymer film can be formed simply by applying a liquid in which this polymer is dispersed to a substrate. For this reason, a polymer film with a uniform thickness can be easily realized on a large-area substrate by using spin coating, slit coating, bar coating, dip, and casting methods, and the manufacturing method is simple and mass production is possible. Is suitable.

  Polyethylenedioxythiophene (PEDOT) and polystyrenesulfonic acid (PSS) in the mixture constituting the conductive polymer are represented by (Chemical Formula 1) and (Chemical Formula 2), respectively. Polyethylenedioxythiophene has the feature that it is less susceptible to oxidative degradation because the β-position of the chemically active five-membered ring is previously modified and inactivated by oxygen. In the mixture, polystyrene sulfonic acid is strongly bonded to polyethylene dioxythiophene by ionic bond.

導電性高分子膜と固体電解質膜の接着性を向上させるためには、導電性高分子にこの分子とは異なる有機分子を混入することが有効であることを本発明者は見出した。特に、有機分子として、ポリビニルピロリドンを用いることでその接着性が際だって向上することを本発明者らは見出した。ポリビニルピロリドンを混合した導電性高分子膜は、導電性高分子分散液または溶液にポリビニルピロリドンを溶解させた液体を作製し、これを基板に塗布した後溶媒を乾燥することにより作製することができる。導電性高分子分散液または溶液（導電性高分子固体含有率１重量パーセント）に対するポリビニルピロリドンの混合割合としては、０．０５重量パーセントから１重量パーセントが好ましく、さらに好ましくは０．０５重量パーセントから０．５重量パーセントである。この範囲よりも少ない場合、導電性高分子膜とイオンゲルからなる固体電解質膜の接着性の向上は得られず、作製したアクチュエータを動作した時に導電性高分子膜と固体電解質膜は剥離し、屈曲動作が困難となる。一方、この範囲よりも多い場合、導電性高分子を膜として得ることが困難になる。

In order to improve the adhesion between the conductive polymer membrane and the solid electrolyte membrane, the present inventors have found that it is effective to mix organic molecules different from these molecules into the conductive polymer. In particular, the present inventors have found that the use of polyvinylpyrrolidone as an organic molecule significantly improves the adhesion. The conductive polymer film mixed with polyvinyl pyrrolidone can be prepared by preparing a liquid in which polyvinyl pyrrolidone is dissolved in a conductive polymer dispersion or solution, applying this to a substrate, and then drying the solvent. . The mixing ratio of polyvinyl pyrrolidone to the conductive polymer dispersion or solution (conductive polymer solid content 1 weight percent) is preferably 0.05 weight percent to 1 weight percent, more preferably 0.05 weight percent. 0.5 weight percent. If the amount is less than this range, the adhesion of the solid electrolyte membrane composed of the conductive polymer membrane and the ionic gel cannot be improved, and when the manufactured actuator is operated, the conductive polymer membrane and the solid electrolyte membrane are peeled off and bent. Operation becomes difficult. On the other hand, when it exceeds this range, it becomes difficult to obtain a conductive polymer as a film.

The solid electrolyte membrane 103 used in the present invention is named an ionic gel in which at least one of a polymer or a monomer dispersed in an ionic liquid is gelled and the ionic liquid is held in the three-dimensional network structure of the gel. The material is flexible and has a value of 10 ⁻² S / cm at room temperature, which is 100 times or more that of a conventional polyether polymer solid electrolyte. Although an ionic gel can be used alone as the solid electrolyte membrane, the ionic gel can also be used by impregnating a porous membrane such as paper or a membrane filter.

  The ionic liquid is also called a room temperature molten salt or simply a molten salt, and is a salt that shows a molten state in a wide temperature range including normal temperature (room temperature).

  In the present invention, conventionally known various ionic liquids can be used, but those which show a liquid state at a normal temperature (room temperature) or a temperature close to normal temperature (room temperature) and are stable are preferable.

Examples of the ionic liquid preferably used in the present invention include those composed of the following cations represented by (Chemical Formula 3) to (Chemical Formula 6) and an anion (X ⁻ ).

  In addition, a monomer (for example, methyl methacrylate, MMA), a crosslinking agent (for example, ethylene glycol dimethacrylate, EGDMA), and a polymerization initiator (for example, azobisisobutyronitrile, AIBN) are dissolved in the ionic liquid. A gel-like composition that becomes an ionic gel even when an organic polymer is formed can be obtained by carrying out a polymerization reaction.

  Hereinafter, the actuator according to the present invention will be described in more detail with reference to examples, but the present invention is not limited thereto.

Example 1
[Preparation of conductive polymer film mixed with organic molecules]
An aqueous dispersion of PEDOT and PSS mixture in which 5% by weight of dimethyl sulfoxide (DMSO) and 0.1% by weight of polyvinyl pyrrolidone K25 are dissolved on a slide glass cleaned with acetone and then subjected to oxygen plasma treatment (trade name, manufactured by Starck Co. A predetermined amount of BYTRON PH500) was dropped. Then, it was naturally dried at room temperature to evaporate the solvent, and a conductive polymer film was formed on the slide glass. Finally, the conductive polymer film was peeled from the slide glass using a razor. The obtained conductive polymer film had an average thickness of 10 μm, and the conductivity measured using a four-end needle method was 320 S / cm.

[Ion gel raw material preparation]
In the ionic liquid for producing the ion gel, ethylmethylimidazolium (EMI) was used as a cation, and bis (trifluoromethanesulfonyl) imide [(CF ₃ SO ₂ ) ₂ N ⁻ ] (TFSI) was used as an anion. As the polymer to be mixed, a vinylidene fluoride / hexafluoropropylene copolymer [P (VDF / HFP)] was used. The mixing ratio of EMITFSI and P (VDF / HFP) was 8: 2, and after mixing, the mixture was sufficiently stirred using a magnetic stirrer. Hereinafter, this mixed solution is referred to as an ion gel precursor.

[Preparation of electrolyte ion gel]
A polyethylene terephthalate (PET) sheet having a thickness of 0.1 mm was cut into a size of 76 mm × 26 mm, and this was adhered to a slide glass having a size of 76 mm × 26 mm. Two sets of this were produced. Then, a slide glass produced by sandwiching a capacitor separator paper having a thickness of 40 μm was adhered so that the two PET sheets face each other with a predetermined gap therebetween. At this time, the capacitor separator paper was impregnated with an ion gel precursor. Thereafter, the mixture was heated at 100 ° C. for 30 minutes in a thermostatic bath, and then cooled to room temperature to obtain an ion gel-impregnated paper having a thickness of 40 μm. The PET sheet and the ionic gel-impregnated paper were easily peeled off because of their extremely low adhesiveness to each other. Hereinafter, the ion gel-impregnated paper obtained here is referred to as electrolyte ion gel.

[Lamination of electrolyte ion gel-conductive polymer film]
Conductive polymer film / electrolyte ion gel / conductive polymer film is formed by superposing conductive polymer films on both sides of the electrolyte ion gel so as to be opposed to each other, heating in a thermostatic bath at 100 ° C. for 30 minutes, and then cooling to room temperature. The three-layer structure was formed. This three-layer structure is cut to a width of 2.5 mm and a length of 15 mm, a platinum electrode having a width of 2 mm and a length of 10 mm is attached to a region of 5 mm in the longitudinal direction from one end, and a flexible conductive high length having a movable portion length of 10 mm. A molecular actuator was fabricated.

  The amount of bending displacement was evaluated by triangular measurement using a laser displacement meter. The measurement point of the triangular measurement was set at a position of 5 mm in the length direction from the electrode mounting portion.

  When a voltage of ± 1.0 V was applied to this actuator, a bending operation was made in response to the applied voltage without peeling at the electrolyte ion gel-conductive polymer film interface. Table 1 shows the amount of displacement when driven by a 1 Hz rectangular wave.

表１から、この構成の屈曲型導電性高分子アクチュエータは導電性高分子膜と固体電解質膜の接着性に優れ、長期動作可能であることが示された。

From Table 1, it was shown that the bent type conductive polymer actuator having this configuration is excellent in adhesion between the conductive polymer film and the solid electrolyte film and can be operated for a long time.

(Comparative Example 1)
A predetermined amount of an aqueous dispersion of PEDOT and PSS mixture (trade name Vitron PH500, manufactured by Starck Co., Ltd.) in which 5 weight percent of dimethyl sulfoxide (DMSO) was dissolved was dropped onto a slide glass that had been cleaned with acetone and treated with oxygen plasma. Then, it was naturally dried at room temperature to evaporate the solvent, and a conductive polymer film was formed on the slide glass. Finally, the conductive polymer film was peeled from the slide glass using a razor.

  Conductive polymer membranes are laminated on both sides of the electrolyte ion gel produced in the same manner as in Example 1, heated at 100 ° C. for 30 minutes in a thermostatic bath, and then cooled to room temperature, whereby the conductive polymer membrane and the electrolyte ion gel are cooled. A three-layer structure was formed by bonding. This three-layer structure is cut to a width of 2.5 mm and a length of 15 mm, a platinum electrode having a width of 2 mm and a length of 10 mm is attached to a region of 5 mm in the longitudinal direction from one end portion, and a bending type conductive high height having a movable portion length of 10 mm is attached. A molecular actuator was fabricated.

  This actuator has extremely low adhesion between the electrolyte ion gel and the conductive polymer film, and when a voltage of ± 1.0 V is applied, peeling occurs at the interface between the electrolyte ion gel and the conductive polymer film, and the bending responds to the applied voltage. Without operation, the displacement was a 1 Hz rectangular wave and the initial 10-time average displacement was 0.05 mm or less.

  According to the present invention, it is possible to easily manufacture a highly reliable actuator that is small, light and flexible, and can be suitably used in fields such as medical, industrial, and home robots or micromachines. it can.
