Abstract
The present invention is a capacitor of a triphenyl phosphine oxide film as a base dielectric. More specifically, the base dielectric film is selected from the group consisting of Bisphenol-A (Bis-A PEPO). 4′,4′-biphenol (BP-PEPO), and Hydroquinone (HQ-PEPO). TPPO based polymers have a very high breakdown strength, dielectric constant, low dissipation factor and high energy density. An ultra-thin coating can leverage the capabilities of this new dielectric, and potentially other commercial polymer films, to make possible energy storage in excess of 1 J/cc. The triphenyl phosphine oxide film can be fabricated containing a conducting PolyANiline (PAN) polymer layer located between the electrode and core polymer, or by being dip coated with PAN.
