Ionic Electroactive Actuators and Sensors with Hybrid Polymer-Metal Electrodes
摘要
Ionic electroactive polymers are considered as electromechanical and mechanoelectrical transducers - actuators and sensors. Transducers with metal (Pt), polymer (PEDOT), and polymer-metal (PEDOT/Pt) hybrid electrodes are prepared. The surface morphology and internal structures of the samples are studied. The measurements of practically important actuation characteristics show that the advantages of transducers with earlier types of electrodes are inherited by those with hybrid electrodes: longer continuous operation in air characteristic of polymer electrodes and higher amplitude and force properties characteristic of metal ones. In the study of the transducer with PEDOT/Pt-electrodes in the sensor mode, the most stable response is obtained when Pt is deposited on the PEDOT external surface in two stages.
