Actuation Behavior of CP Actuator Based on Polypyrrole and PVDF
Conducting polymer (CP) actuators undergo volumetric changes due to the movement of dopant ions into the film during the electrical oxidation process. In this work, 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 (PPy) films and a solid polymer electrolyte (SPE) based on poly(vinylidene fluoride) (PVDF), clearly showed a reversible displacement in an atmosphere when a voltage was applied.
