ABSTRACT:
An electrical device includes two electrodes and a conductive polymer layer, containing a mixture of a polymer and a conductive filler, separating the electrodes. A oxygen barrier material containing a thermosetting polymer component is present on the exposed surface of the conductive polymer layer that is not in contact with the laminar electrodes. The oxygen barrier material may be a polyamine-polyepoxide material, and may provide for acceptable barrier properties over a wide range of humidity levels.
