Patent ID: 7371459

Claim:
An electrical device, comprising: a first electrode; a second electrode; a conductive polymer layer separating the first and second electrodes, said conductive polymer layer (i) having an exposed surface not in contact with the first and second electrodes, and (ii) comprising a mixture of a polymer and a particulate conductive filler which comprises nickel; and a thermoset oxygen barrier material comprising a thermosetting polymer component on the exposed surface of the conductive polymer layer, at least 65 weight percent of the polymer component of the oxygen barrier material 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 —; -Aryl- being selected from the group consisting of phenylene, naphthylene and anthracenyl.
