The present invention provides a method for making a polymer dielectric composition incorporating diamondoids or diamond-like hydrocarbon units. The method includes forming a polymer solution from the cardo-diol 9,9-bis(4-hydroxyphenyl)fluorene and a diacid chloride, casting a freestanding thin polyester film from the polymer solution, and metallizing the polyester film with an evaporated Al layer to form the dielectric composition. The diacid chloride may be derived from trans-1,4-cyclohexanedicarboxylic acid; 1,3-adamantanedicarboxylic acid; or 4,9-diamantanedicarboxylic acid.

Method for making high temperature polymer dielectric compositions incorporating diamond-like hydrocarbon units for capactive energy storage applications

An energy storage arrangement wherein electrical charge is stored in capacitor elements dispersed throughout, for example, surface structural components of an aircraft. The electrical capacitor elements may involve dielectric material-separated electrical plates comprising the aircraft skin or preferably may involve numerous wire-like cylindrical capacitor elements dispersed within the weaving of the hardened fabric materials used to fabricate the aircraft. Other elements of the aircraft including internal structure and divider members may also be included in the energy storage function. Pulsed use of the stored energy in, for example, directed energy weapons devices are a contemplated application of the invention. The invention may be viewed as a combined employment of aircraft components in both structural and energy storing functions thus enabling a reduction in aircraft payload utilization and space consumption.

Airframe structure-integrated capacitor

One aspect of the present invention is directed to a capacitor. The capacitor includes a first layer and a second layer. The first layer includes a first electrically conductive substrate having a first surface and a second surface. A first dielectric film is deposited on the first surface of the first substrate and a second dielectric film is deposited on the second surface of the first substrate. The second layer contacts the first layer. The second layer includes a second electrically conductive substrate having a first surface and a second surface. A third dielectric film is deposited on the first surface of the second substrate, and a fourth dielectric film is deposited on the second surface of the second substrate.
