  • Capacitor having an enhanced dielectric breakdown strength
    Patent number: 5636100
    Abstract: A capacitor having an enhanced dielectric breakdown strength is obtained m a base dielectric film by coating the base dielectric film on both sides with an adherent coated dielectric film having a dielectric constant that is at least 50 percent higher than that of the base dielectric film and that adheres to the base dielectric film; and wherein metal foil is adherently joined to each of the coated dielectrics films to form electrodes for the capacitor.
    Type: Grant
    Filed: June 27, 1995
    Date of Patent: June 3, 1997
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Jian-Ping Zheng, T. Richard Jow, Peter J. Cygan
  • Cyanoresin, cyanoresin/cellulose triacetate blends for thin film, dielectric capacitors
    Patent number: 5490035
    Abstract: Non brittle dielectric films are formed by blending a cyanoresin such as cyanoethyl, hydroxyethyl cellulose (CRE) with a compatible, more crystalline resin such as cellulose triacetate. The electrical breakdown strength of the blend is increased by orienting the films by uniaxial or biaxial stretching. Blends of high molecular weight CRE with high molecular weight cyanoethyl cellulose (CRC) provide films with high dielectric constants.
