▎ 摘　　要

NOVELTY - A polymer actuator comprises a pair of opposing composite electrodes containing a conductive polymer and chemically doped graphene obtained by microwave irradiation, an ionic polymer membrane positioned between the electrodes and containing 60-80 pts. wt. ionic liquid having a sulfonic acid group with respect to 100 pts. wt. ionic polymer, and a voltage applying unit for applying voltage to the pair of composite electrodes. USE - Polymer actuator for flexible robot and haptic device. ADVANTAGE - The polymer actuator exhibits excellent operating displacement under low drive voltage, performance persistence and operating force. The chemically-doped graphene can be manufactured by simple method with high productivity.
