Nanocomposite Dielectric Film Navy SBIR FY2012.1 Sol No.: Navy SBIR FY2012.1 Topic No.: N121-095 Topic Title: Nanocomposite Dielectric Film Proposal No.: N121-095-0495 Firm: Physical Sciences Inc. 20 New England Business Center Andover, Massachusetts 01810-1077 Contact: John Lennhoff Phone: (978) 689-0003 Web Site: http://www.psicorp.com Abstract: Physical Sciences Inc. (PSI) proposes to demonstrate the advantage of using a coupling agent to bind ceramic dielectric nanofillers uniformly within a high temperature polymer matrix. On the proposed Phase I program, PSI will enhance the energy density of nanocomposite dielectric polymer films by utilizing oxide ceramic nanoparticle fillers with a commercially available chemistry that binds to both the ceramic and polymer components. During the Phase I effort, PSI will demonstrate the technology to produce lab scale dielectric films and characterize the films for permittivity, dielectric loss and film resistance. PSI will be assisted by Prof. George Rossetti at the Institute of Materials Science, University of Connecticut on the proposed program. During a Phase I Option, we will perform film pilot scale runs at our partner, Frontier Industrial Technology. A Phase II program will include further films scale-up, characterization of defects and failure mode, and fabrication of 10 J rolled capacitors with our partner, Arizona Capacitors. Benefits: Large pulsed power capacitors with high energy density have commercial applicability in power conditioning and power back-up applications. Hybrid vehicles and portable power tools and construction vehicles could benefit during high power utilization operation by high density capacitors. The easy processability of polymer based nanocomposite dielectrics with high energy density would bring down capacitor cost per watt and expand their use. Return
