Among various conducting polymers (CPs), polypyrrole (PPy) is most promising materials in view point of low operating voltage, ease of synthesis and large stress. In this study, the construction of a new solid state CP actuator based on PPy nanocomposite film electrodes and a solid polymer electrolyte (SPE). In CP actuator, ions are shuttled between the two PPy nanocomposite films during elelctrochemical switching. PPy nanocomposite was electrochemically polymerized from aqueous dispersions of pyrrole monomer containing carbon black. And then PPy nanocomposite was characterized by using 4-point probe technique and scanning electron microscopy. We constructed PPy nanocomposite/SPE/PPy nanocomposite tri-layer actuator. The nanocomposite gave good electrical contact over the entire actuator. All the results obtained in this work show the feasibility of electrochemomechanical devices based on PPy nanocomposite and SPE film able to work in air. |
