Ultra-high Dielectric Constant Dielectric Materials

NON-NUCLEAR APPROACHES ARE SOUGHT FOR HIGH ENERGY DENSITIES FOR SPACE POWER SYSTEMS. ONE CRITICAL COMPONENT TO ACHIEVE IMPROVED PERFORMANCE IS CAPACITOR STORES. THESE ARE DEPENDENT UPON ADVANCES IN LOW LOSS, HIGH ENERGY/HIGH POWER DENSITY STORAGE MATERIALS. A UNIQUE INORGANIC COMPOSITE IS PROPOSED FOR INVESTIGATION AS A HIGH ENERGY DENSITY STORAGE MATERIAL. AN APPROACH IS FORMULATED BASED ON SOL-GEL CHEMISTRY AND POLYMER PHYSICS WHICH WILL ALLOW MATERIALS WITH DIELECTRIC CONSTANTS AS LARGE AS 100 TO BE DEVELOPED. PREDICTED BREAKDOWN STRENGTHS ARE GREATER THAN 3MV/cm. THIS REPRESENTS A SIGNIFICANT MATERIALS BREAKTHROUGH. PHASE I ACTIVITIES INCLUDED: SYNTHESIS OF THE INORGANIC/ORGANIC COMPOSITE AND INVESTIGATIONS TO OPTIMIZE THE MATERIAL; FABRICATION OF FILMS; AND CHARACTERIZATION OF THE DIELECTRIC FILMS TO INCLUDE BOTH MECHANICAL AND ELECTRICAL TESTING. DESIGNS FOR ADVANCED CAPACITORS WILL BE DEVELOPED AND PHASE II RECOMMENDATIONS FORMULATED. TPL HAS EXTENSIVE EXPERIENCE IN SOL-GEL CHEMISTRY AND DIELECTRIC MATERIAL SYNTHESIS.
