Abstract

IPMC(Ionic Polymer-Metal Composite) is promising candidate material for bio-related actuators mainly due to its biocompatibility and wet and soft properties. The widely used commercialized Nafion film has a few kinds of fixed thicknesses but more various film thicknesses are required for extensive applications. Especially for the enhanced force as an actuator, the thick film is essential. Various Nafion films with thickness of 0.4-1.2mm have been prepared by casting of liquid Nafion. Also, IPMC actuators using casted Nafion films have been fabricated and the basic mechanical properties such as stiffness, displacement and force were measured and analyzed. These results can be used for the optimized design of actuators for different applications.
