Actuative Properties of CP Actuator Consisting of Polypyrrole Film and Solid Polymer Electrolyte

Conducting polymer (CP) actuators undergo volumetric changes due to the movement of dopant ions into the film during the electrical oxidation process. However, it may be an impediment for practical use of polypyrrole actuator that polypyrrole usually requires electrolyte solution for actuation. To solve this problem, solid polymer electrolyte(SPE) was introduced in CP actuator instead of electrolyte solution. And PPy/SPE/PPy electroactive tri-layer actuator was prepared by the electrochemical polymerization of pyrrole and the actuation characteristics were studied. An all-solid actuator, consisting of two polypyrrole films and a solid polymer electrolyte based on polyurethane, clearly showed a reversible displacement in an atmosphere when a voltage was applied.

Polymer Actuator

The fabrication of dry type conducting polymer actuator was presented. In the preparation of actuator system, nitrile rubber (NBR) was used as a base material of the solid polymer electrolyte. Thin films of NBR (150-200μ m) were prepared by compression molding process. The conducting polymer, poly (3,4- ethylenedioxythiophene) (PEDOT) was synthesized on the surface of NBR by chemical oxidation polymerization technique, and the room temperature ionic liquid, 1-ethyl-3- methylimidazolium bis (trifluoromethyl sulfonyl) imide (EMITFSI) was introduced into the composite film. The ionic conductivity of new type solid polymer electrolyte as a function of the immersion time and the cyclic voltammetry responses and the redox switching dynamics of PEDOT in NBR/ionic liquid solid polymer electrolyte were studied. The displacement of actuator was measured by laser beam radiation.
