Nafion based precious metal plating ion conductive polymer-gel film (ICPF) actuator is very attractive because of its high-speed response and softness of the material. The deformation characteristics, especially the direction of residual strain changes with the density or the amount of the Na^+ driving ion. In the case of Au-Nafion ICPF the difficulty of the positioning control mainly depends on the direction of the residual strain. If the direction of the residual strain is the same to the initial strain, we can control the position of the ICPF by integral feedback control method. Therefore, we have to to keep the direction of the residual strain of ICPF. To keep the direction, we have to prevent the leakage of Na^+ driving ion from inside the ICPF. In this paper, we found that 0.1% NaOH solution could prevent the leakage of Na^+ ion and the long time positioning control of long time was enabled by this condition.
