Research on Preparation and Stacking Performance of IPMC

In order to improve the performance of IPMC, a chemical deposition method was utilized to manufacture IPMC with silver electrodes (Ag-IPMC), and methods of ion exchange and ionic liquid penetration were adopted to conduct modified treatment for original IPMC. Additionally, the stacking performance of IPMC, which was disposed by ionic liquid penetration after the modified treatment, was analyzed. Results showed that: Ag-IPMC, which was modified by treating in 2mol/L LiCl solution for three hours, presented the optimal performance. Also, the IPMC after modified treatment by ionic liquid penetration swung longer in air, and its tip output displacement was stable at five millimeter; without any change with time. Furthermore, the stacked model of IPMC decreased the excursion of center in the process of swinging, and it also increased the output force of IPMC. The stacked model, which was composed with 3 sheets of IPMC after modifying treatment by ionic liquid penetration, was verified to have the optimal performance.
