Abstract
An electro-active device is disclosed that may comprise a buffer immobilized on one or more films. The electro-active device may comprise a first substrate, a second substrate, a first electrode, and a second electrode. The first and second substrates may be disposed in a spaced apart relationship. Further, the first electrode may be associated with the first substrate and the second electrode may be associated with the second substrate. Additionally, a cathodic film may be associated with one electrode and an anodic film may be associated with the other electrode. The anodic film may comprise an anodic compound immobilized thereon and the cathodic film likewise may comprise a cathodic compound immobilized thereon. Further, a buffer component may be immobilized on the cathodic film and/or the anodic film.
