Abstract

This chapter mainly introduces physical deformation theory of IPMC actuator. At first a series of comparative experiments focused on water content and polymer backbones of IPMC were designed and performed to disclose the actuation mechanisms of relaxation and slow anode deformation. Then a multi-physical model was set up which emphasized on water-related transport process and various eigen stresses. Through numerical analysis, inter-coupling between cation and water, pressure and hydration effects were investigated on the transport process. And in contrast to hydrostatic pressure, osmotic pressure and electrostatic stress and their properties with cation and water concentrations were analyzed to explain IPMC deformation evolvement with water content. Finally, model simplification was discussed for deformation prediction in engineering application.
