A series of high dielectric constant polymers have been developed with K from 10 to over 50. The high-K polymers have high dielectric breakdown strength above 700 Vmicron and high energy density up to 27 Jcc in lab-scale small sample test. The capacitor film was produced by using melt-extrusion and biaxial orientation process and film thickness from 2 micron to 10 micron has been achieved. Metallized prototype capacitors show promising performance with energy density above 3 Jcc. Future development will target at 10 Jcc energy density in the packaged capacitors. Potential applications include pulsed power capacitors for medical defibrillators, high-power X-Raylaser system, and direct energy weapon systems.
