All‐Solid Actuator Consisting of Polyaniline Film and Solid Polymer Electrolyte

An all‐solid actuator, consisting of a polyaniline (PANI) film and a solid polymer electrolyte (SPE) of poly(ethylene oxide) derivative (STO288), clearly showed a reversible displacement in an atmosphere when a voltage was applied between the PANI film and the SPE layer. The displacement and the response rate are mainly dependent on the applied voltage and the employed supporting salt, but are influenced by the humidity and temperature of the environment. The results of the present experiments have revealed that the influences of the humidity and temperature on the performance of the actuator are predominantly through the ionic conductivity of the SPE.
