Ionic polymer metal composite(IPMC),a new kind of smart material,with remarkably large strain and stress under low-voltage stimulation,has been extensively studied in recent years.In this paper,a new kind of IPMC actuator was fabricated by sandwiching a Nafion film between two sulfonated carbon nanotube/Nafion electrode films by hot-pressing method,and then plated gold electrode on the surface to overcome some major drawbacks of conventional IPMC actuators.
