Positioning control of Nafion-Au ionic polymer metal composite (The Effect of Counter Ion on The Deformation Patterns of IPMC)

摘要

This paper describes the positioning control method of Au-Nafion IPMC. Au-Nafion IPMC can be classified into two types whether the residual strain is generated to the cathode side(SDT) or the anode side(ODT). SDT can be controlled its position by normal integral control. ODT can also be controlled by restricting the maximum changing speed in the integral control. Experimental result showed the close relationship between the direction of the residual strain and the density or the amount of the counter ion.
