摘要： Sheet capacitive materials for use in forming a thin-film capacitor comprise an electrically nonconductive substrate, a layer of electrically conductive material disposed a surface of the substrate, and a layer of electrically nonconductive material disposed onto a surface of the conductive material layer. The conductive material layer includes a contact area along a first lengthwise edge of the substrate that is thicker than remaining portions of the material layer. A portion of the substrate adjacent a second lengthwise edge remains exposed. The electrically nonconductive material includes an anti-stick component, and covers the exposed substrate surface and a major portion of the material layer except for the contact area. A first and second sheet is constructed having contact areas along opposite lengthwise edges. The sheets are placed together so that the contact areas are oriented at opposite lengthwise edges, and are staggered so that the contact areas remain exposed. The sheets are wound together in a spiral to form a roll having a contact area at each respective end. Metal is sprayed onto the exposed contact areas to form capacitor electrodes. A thin-film capacitor formed from such sheet capacitive materials have improved properties of corrosion resistance and self healing when compared to conventionally constructed thin-film capacitors.

摘要： A thermoplastic container or packaging material is given low oxygen permeability by coating with a crosslinked acrylate layer and a layer of oxygen barrier material deposited over the acrylate layer. Another acrylate layer may be deposited over the oxygen barrier. The oxygen barrier is selected from the group consisting of silicon oxide, aluminum oxide and metal. The acrylate layer may be formed from a photopolymerizable polyfunctional acrylate that is sufficiently low viscosity to be sprayed on the substrate or applied by dipping. Alternatively, the acrylate layer is a polymerization product of an acrylate monomer which is evaporated in a vacuum, condensed on the substrate and polymerized by irradiation by ultraviolet or an electron beam. The surface of the thermoplastic substrate is prepared for deposition of the acrylate by either flame treating the surface of the substrate to heat it above its melting point without deforming the substrate to thereby smooth the surface, or by plasma treating the surface for enhancing adhesion of the acrylate. Chilling the substrate enhances deposition efficiency.

摘要： Material for winding high voltage capacitors is prepared by evaporating polyfunctional acrylate monomer having a molecular rate in the range of from 150 to 600 and condensing the acrylate as a monomer film on a dielectric substrate. The acrylate is polymerized by irradiation by ultraviolet or electrons. Sometimes both faces of the dielectric are coated to protect the thermoplastic dielectric from swelling when exposed to dielectric liquid. The metallized layer provides an electrode of the capacitor. A polymerized acrylate layer may be applied over the metal layer. Electrical contact can be made to the metal layer by Schooping even though the metallized layer is covered by a layer of acrylate. Low oxygen permeability polypropylene, polyester or nylon sheet has a layer of crosslinked acrylate and an oxygen barrier layer formed of silicon oxide, aluminum oxide or metal. Adhesion is enhanced by plasma or corona treatment of a surface immediately before deposition. Condensation efficiency is also enhanced by chilling the substrate on which the acrylate is condensed.

摘要： Several techniques may be used for forming a colored interference filter coating on a substrate such as polyester film. The interference filter has two metal reflective films, at least one of which is semi-transparent. A layer of transparent acrylate polymer dielectric between the metal layers completes the interference filter, which may be sandwiched between protective layers. The dielectric is formed by evaporating an acrylate monomer having a molecular weight in the range of from 150 to 600. Preferably the acrylate monomer has a molecular weight to acrylate group ratio in the range of from 150 to 400. The acrylate condenses on the substrate and is polymerized in situ for forming a monolithic film with a sufficient thickness to produce an interference color. In several embodiments different areas of the film have different thicknesses for producing different interference colors. The thickness of the dielectric can be controlled by the amount of monomer condensed, by either controlling the temperature of the condensation surface or controlling the amount of monomer evaporated adjacent a predetermined area of the substrate. Thickness may also be controlled by condensing a uniform layer of monomer and polymerizing the monomer to different degrees for varying the shrinkage of the film and hence the thickness of the film and color.
