EAPs can produce large deformation with lower applied voltage for actuation applications. IPMC (Ionic Polymer Metal Composite) is a well-known ionic EAPs. It has numerous attractive advantages, such as low electrical energy consumption and light weight. The mechanism of IPMC actuator is due to the ionic diffusion when the voltage gradient is applied, so that the type of ionic solution has a large impact on the physical properties of IPMC. In this paper, the reliability tests of IPMC with non-aqueous ionic solution are demonstrated. Pt-IPMC with LiOH aqueous solution exhibits the best maximum displacement, but the water in LiOH solution is electrolyzed because of the low electrolysis voltage 1.23 V of water. To improve electrolysis problems and the operation time in the air, proper solvents including high electrolysis voltage and low vapor pressure should be considered. The reliability tests focus on the durability of IPMC in the air. The surface resistance, tip displacement and response time of IPMC are presented. More improvements of IPMC fabrication, such as Ag-IPMC, was developed in this paper. © 2014 SPIE. |
