Research Institution
For this Phase I SBIR, high energy storage capacitors are proposed based on the breakthrough technology of large dielectric permittivity polymers. Based on the P(VDF-TrFE) systems, these polymers exhibit relaxor ferroelectric behavior when irradiated; that is, high dielectric permittivity (sr~l OO) over a broad diffused temperature region.With these high dielectric constant and low loss polymers, energy storage levels of greater than 25 Joules/cm3 are projected, nearly an order of a magnitude larger than existing polymer dielectrics. In this program, chemical engineering of P(VDF-TrFE) polymers, as well as processing and metallization methods to optimize key parameters relevant to pulse power operation will be investigated. Single layer polymer capacitors will be tested for energy storage capability including dielectric breakdown strength (DBS), discharge rate, dielectric loss under E-field, etc., to establish the potential of this new class of dielectrics for ultimate manufacturing of pulse power capacitors in Phase II.
