Development of High Interfacial Area Actuator and Characterization of Its Electrochemical Behavior

초록

In recent, there were demands for highly active sensors, flexible and miniaturized actuators at many fields such as metal composite(IPMC) and conducting polymer had been discussed as various types of sensors ans actuators. IPMC had larger deformation at low voltage than other polymers, but has some problems. As the deformation was due to the excess amount of water near the cathode, electrolysis of solution at high voltage and loss of solution in dry environment decrease the deformation of IPMC. The deformation of IPMC was affected by several factors such as the hydrated sphere around moving cations inside nafion electrolyte and the interfacial area between the electrodes and polymer electrolyte.
