Notes:
Conducting polymer (CP) actuators undergo volumetric changes due to the movement ofdopant ions into the film during the electrical oxidation process. However, it may be an impediment forpractical 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 ofelectrolyte solution. And PPy/SPE/PPy electroactive tri-layer actuator was prepared by theelectrochemical polymerization of pyrrole and the actuation characteristics were studied. An all-solidactuator, 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
