Development and Processing of Dielectric Films for Application in Large Wound Capacitors Navy SBIR FY2012.1 Sol No.: Navy SBIR FY2012.1 Topic No.: N121-095 Topic Title: Development and Processing of Dielectric Films for Application in Large Wound Capacitors Proposal No.: N121-095-0942 Firm: PolyK Technologies, LLC 2438 Setter Run Ln State College, Pennsylvania 16801 Contact: Nanyan Zhang Phone: (518) 894-4886 Abstract: In this SBIR Phase I project, we will develop polymer dielectric compositions based on the blends of a high-temperature polymer with high dielectric constant and relatively high dielectric loss with a second high temperature polymer with low dielectric constant and low dielectric loss. The dielectric loss and leakage current of the polymer blend will be balanced with the dielectric constant by optimizing the blend compositions. The processing technology of the polymer blend will be developed to achieve either thermodynamic miscibility or homogeneity morphology in order to have high dielectric breakdown strength and high energy density. It is expected that the optimized polymer blend capacitor film will combine high energy density, high charge-discharge efficiency, high electric resistivity, and high thermal stability. Benefits: The high energy density film capacitors with high thermal stability will find applications in military pulsed power systems, medical defibrillators, and power electronics in renewable energy industries such as hybrid or plug-in electric vehicles, wind turbine generators, grid-tied photovoltaics, as well as power regulation and managment in smart grid.
