Paper Abstract

In this paper, the effect of driving frequency on the actuation characteristics of ionic polymer-metal composites (IPMCs) is studied. The charge motion within the polyelectrolyte membrane under a dynamic electric potential is first formulated and investigated. Subsequently, the dynamic ion-ion interactions within the polyelectrolyte membrane clusters are studied. By analyzing the volumetric changes of the membrane clusters due to the electric field induced stresses and the elastic stresses in the backbones of the membrane, the bending moment expression due to the applied electric potential is obtained. By using this bending moment expression, the vibrations of an IPMC cantilevered beam subjected to electric potentials of different frequencies are calculated. The characteristics of the IPMCs behavior are discussed with comparison with experimental results.
