High Energy Density Dielectrics for Pulse Power Capacitors

Eikos Inc. proposes to develop high dielectric constant (K), low loss nanocomposite polymers to meet the design objectives of high energy density (HED) capacitors. In the proposed Phase I program, we will apply rigorous computational techniques to predictthe properties of this new class of nanocomposites. We will compound nanocomposite resins, fabricate films for testing, and measure the electrical properties. Initial calculations and testing indicate that these polymers will have better dielectricproperties than analogous polymers lacking nanotubes. The development of nanocomposite materials is crucial to overcoming the current plateau in dielectric materials development. This technology lends its self to application and enhancement of existingpolymer and ceramic dielectric materials. The development of high dielectric constant, low loss dielectrics will have immediate application in meeting the needs for high energy density capacitors.The compact, high temperature and high-energy density DLCcapacitors have myriad uses in both commercial and military applications. These include applications such as domestic utilities and appliances, well drilling equipment, power supplies, aircraft, satellites, trains, automobiles and medical devices. The hightemperature capability of the capacitors will enable electronic devices to be mounted close to aircraft engines. This enables more sophisticated engine actuators, sensors and controls to be implemented with a net reduction in weight achieved through thereduction or even elimination of wiring hardware, which is necessary when the electronics have to be remotely located. High-energy density capacitors are also greatly needed for Air Force and Army pulse power applications. Eikos has already startednegotiations with venture capital firm for securing financing for commercialization of this promising technology.
