Electroactivated film with polymer gel electrolyte
First Claim
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.

Abstract
An electroactivated film and methods for its production are described, where the film 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, which comprises a water insoluble polymer gel containing an ionic liquid, 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.

11. In a method of producing an electroactivated film suitable for surface decontamination 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 comprising forming the water insoluble electrically conductive medium which is permeable to moisture and oxygen by crosslinking a polyvinyl alcohol/amine copolymer with a polymer selected from carboxymethyl cellulose, polyvinyl alcohol and polyethylene oxide in the presence of an ionic liquid to form a polymer electrolyte gel, wherein the electroactive film is fabricated onto a surface of a substrate. - View Dependent Claims (12, 13, 14, 15, 16)
