Paper Abstract

A microwave switch based on EAP presents several advantages. A switch based on Flemion is studied. Flemion a perfluorinated carboxylic acid membrane shows improved performance as actuator material compared with Nafion (perfluorinated sulfonic acid). Flemion has a higher ion exchange capacity and good mechanical strength. In order to get a good Flemion actuator, highly conductive soft gold electrodes with large fractal structure have to be deposited on the membrane. The impregnation reduction technique used for plating requires exchange of a gold complex and reduction by gradual sodium sulfite additions. K+ shows the highest exchange ratio with the gold complex and reducing bath temperatures around 60°C with enough reducing agent present are shown to promote the growth of a gold fractal structure. The resulting material shows an actuation displacement with no relaxation, a key feature for switch applications. A simple mechanical switch based on a flemion actuator is prepared and tested as a microwave switch.
