AbstractThe development of capacitor stores are dependent upon advances in low loss, high energy/high power density storage materials. A unique polymer material is proposed as a high energy density storage material. The molecular structure of the polymer will be engineered to achieve a high, nonlinear dielectric constant and a high, nonlinear dielectric strength. Predicted properties are a dielectric constant greater than 30 and a voltage breakdown strength greater than 3 MV/cm, resulting in an energy storage density greater than 10 MJ/m3. The dielectric molecular engineering concepts that will be employed have been demonstrated on a first generation material that has a dielectric constant of 16 and a dielectric breakdown strength of 1.24 MV/cm. The dielectric material will be processable with no residual stresses, will wet other capacitor components and can be fabricated into unique morphologies. The polymer will be synthesized, fabricated into films and characterized. Designs for advanced capacitors will be presented.
