1. In an electroactivated film that includes a first electrode that is spaced apart from a second electrode, a water insoluble electrically conductive medium which is permeable to moisture and oxygen and which contacts both electrodes, an electrocatalyst which can be reversibly oxidized and reduced and which facilitates the production of a peroxide when an electrical potential is imposed across the electrodes, and optionally a peroxide-activating catalyst which converts the peroxide to an activated peroxide;

  • the improvement wherein the water insoluble electrically conductive medium which is permeable to moisture and oxygen comprises a water insoluble polymer gel containing an ionic liquid, a polyvinyl alcohol/amine copolymer, a polymer selected from the group consisting of carboxymethyl cellulose, polyvinyl alcohol, and polyethylene oxide, and a crosslinking agent.
