Abstract
Abstract An electrical device is presented having unusual electrical properties, the physical configuration of the device being generally characterized as having a pair of conductive sheets or plates with a layer of a polymeric association product sandwiched between the plates which in many aspects behaves like a solid electrolyte. The association product comprises constituent materials which are characterized by ionic donor or acceptor sites or interstitial ionic impurities; and in particular, as used in this invention, an association product is a class of materials having molecular weight in excess of about 5,000 and which is characterized by a multiplicity of ionic acceptor and donor sites distributed along or pendant to a molecular chain, such material commonly being characterized by solubility of from 2 to 100 or more grams of the material per liter of water, and having tensile strength in excess of 10 pounds per square inch. The general class of constituent materials may range from low molecular weight liquids to high molecular weight solids. A particular important and attractive application for the device is that of a capacitor, but many other applications are possible.
