Nanocomposite Dielectric Materials for High Frequency Applications
72258-High power systems for electromagnetic wave generation, particle acceleration, and future fusion technology require large, efficient power supplies and pulse-forming networks. However, due to the very large volume required for the capacitor component, many pulse power applications are limited in performance and practicality. This project will develop a revolutionary dielectric material system, which, when incorporated in a capacitor, will provide an energy density capacity an order of magnitude greater than conventional technologies. The material will overcome the physical and electrical performance limitations of conventional dielectrics required for pulse power systems. Phase I successfully performed and established the feasibility for fabricating structured nano-composite dielectrics. Measured electrical performance of the materials, including dielectric strength and enhanced dielectric constant, support the expectation for a significant increase in energy density. Phase II will continue the development of the structured nano-composite dielectrics for application in high energy density power sources. Formulations and processing conditions will be established to fabricate the dielectric in physical forms (e.g., film, sheet and moldings) for application in a range of pulse power systems. Commercial Applications and Other Benefits as described by awardee: The technology associated with this work has significant utility in a number of current and future pulsed power systems throughout the DOE and DOD. The development of high energy electrical storage and pulse-forming systems, with reduced size and weight, should be applicable to a range of pulse power applications such as fusion-based power generation, particle beam accelerators, high power microwaves, lasers, electric guns, and armor. In addition, a target commercial application for the technology is for compact heart defibrillators.
