Relaxors Terpolymers for Energy Storage Capacitors

In this program, Penn State, TRS Technologies, and Electronic Concepts, Inc. (ECI) worked together to perform a preliminary investigation of various issues related to the ferroelectric relaxor terpolymer for energy storage capacitors. In this program, terpolymers of P(VDF-TrFE-CFE) with different compositions were synthesized, and some of them were fabricated into thin films at ECI. The authors also characterized the electric energy density and the AC and DC resistivities of the terpolymers; investigated the graceful failure and improvement in the breakdown strength and the graceful failure of the terpolymer films; and designed and fabricated a high-voltage and high-speed discharge circuit. The results are summarized in this report. (11 tables, 13 figures)
