Conducting polymers (CPs), such as polypyrrole (PPy), polythiophene and polyaniline, have complex dynamic structure. Their films can be easily deformed by the application of small voltage and current to change volume during their electrochemical redox process. In them, PPy is one of most promising materials in view points of good environmental stability and ease of synthesis.In the development of CP actuators, most studies have been concentrated on improving the strain and response time. However although major advances in actuator performances have been obtained in the last few years, the actuation of CP actuator is still limited to bending movement in liquid electrolyte. It restricts the application of CP actuator in semiconductor devices, position control devices, and medical instruments. So in this study, spring type CP actuator which can produce linear movement using two PPy films having different actuation mechanism and solid polymer electrolyte working in air was prepared. |
