Abstract
An ionic polymer composite device and methods for fabricating the ionic polymer composite device are provided. The ionic polymer composite device includes two extended electrode layers, each extended electrode layer including at least one ionic polymer with a plurality of electrically conductive particles, and a dielectric layer including at least one sulfonated poly ether sulfone polymer or a derivative between the two extended electrode layers.
Claims35
An ionic polymer composite device comprising:
- two extended electrode layers, each extended electrode layer comprising a first ionic polymer and a plurality of electrically conductive particles, wherein the plurality of electrically conductive particles forms a concentration gradient in each of the two extended electrode layers, the concentration gradient has an increasing concentration toward an outer surface of each of the two extended electrode layers;
- and
- a dielectric layer comprising a second ionic polymer between the two extended electrode layers, wherein the second ionic polymer is a second sulfonated poly ether sulfone polymer or a derivative thereof.
