Abstract

The positioning control of IPMC is generally considered difficult. Our previous study, however, clarifies that IPMC's position can be controlled by integral control if the residual deformation remains in the same side of the initial deformation. In this study, the effects of the positive counter ions and the negative ions on the deformation characteristics were examined. The direction of the residual strain was changed by the pH of the negative ion at around pH5.5 - pH6. If the pH is more alkaline, IPMC can be controlled its position. A mechanism of residual deformation is proposed.
