摘要

Ionic polymer membranes are commonly used in fuel cell power generation, water electrolysis and desalinization, chlorine generation, and other niche applications. A more recent development is the potential use of these materials as electromechanical actuators and sensors. Currently, the performance characteristics and high cost of these actuators has prevented them from experiencing widespread use. This paper discusses novel approaches to overcome these obstacles. At this time ionic polymer actuators are only made using gold or platinum as the electrode in a lengthy and labor-intensive process. The current research focuses on using less costly metals and revising the metal deposition process. Several new methods allowing for faster deposition of metals onto ionic polymer membranes are developed and evaluated including electroless plating and impregnation/reduction. Using these methods, ionic polymer actuators have been made with nickel and copper electrodes and results show that they have the potential to perform as well as gold-electroded actuators. Also evalutated are actuators made with sputter-coated gold electrodes. The importance of the use of noble metals and the formation of dendritic electrodes is evaluated. Although interpenetration of the electrode is desireable for good adhesion and better actuator performance, electromechanical coupling is demonstrated without. Results demonstrate that non-precious metals are very effective as electrodes, but oxidation of the electrode is identified as the key issues with their use. Attempts are made to overcome this issue using thin gold protective coatings. Although the gold coatings improve the performance of the acutators, they are not effective in preventing the oxidation. Performance and longevity metrics for actuators made using these new methods are presented and future work is discussed.
