摘　　要：本文通过湿法涂膜和热压复合的方法,制备了基于活性炭-离子液体凝胶的电致动膜材料。使用电化学循环伏安法和原位激光位移传感器分别测定了不同活性炭含量对电致动膜材料的界面电容和电致动位移性能的影响。结果显示膜材料的界面电容和电致动位移性能随着活性炭含量增加而增加。A series of active carbon-ionic liquid gel based electric actuator membranes were fabricated by coating and hot pressing processes. By using cyclic voltammetry and in-situ laser distance sensor,the electrochemical double-layer capacitances and the elec- tromechanical properties of the actuator membranes were estimated. Results suggested that both of the capacitance and the maximum displacement of the actuator membrane increased with the increasing of the amount of active carbon in the membrane.
