  • Publication number: 20110133607
    Abstract: A polymer actuator containing graphene and a method of preparing the same are provided. The polymer actuator includes an ion-conductive polymer membrane, a metal electrode disposed on both surfaces of the ion-conductive polymer membrane, and graphene dispersed within the ion-conductive polymer membrane. As the graphene is dispersed within the polymer membrane, reverse ion migration due to an osmotic pressure occurring after solvent migration caused by electrostimulation in operation of the actuator can be prevented, and thus drivability of the polymer actuator can be improved.
