Patent ID: 7632373

Claim:
A method of making an electrical device, comprising: forming a laminate of a conductive polymer layer, a first electrode, and a second electrode, the conductive polymer layer comprising a mixture of a polymer and a conductive filler, and the laminate comprising an exposed surface between the first and second electrodes; and covering at least a portion of the exposed surface of the conductive polymer layer with a thermoset oxygen barrier material comprising a thermosetting polymer component, at least 65 weight percent of said polymer component comprising two or more groups selected from the group consisting of >N—CH 2 -Aryl-CH 2 —N<, >N-Aryl-N<, —O-Aryl-O—, —O(O═)C-Aryl-C(═O)O—, —O(O═)C—CH 2 -Aryl-CH 2 —C(═O)O—, and —CH 2 —CH(OH)—CH 2 —; wherein -Aryl- is selected from the group consisting of phenylene, naphthylene and anthracenyl.
