Abstract

High-temperature and high-energy-density polymer dielectrics for capacitive energy storage are critical in capacitors orient to harsh-environment application. The dielectric properties of poly(tetrafluoroethylene-hexafluoropropylene-vinylidene fluoride) (THV) terpolymer are investigated in a broad temperature range. It was found that the thermal stability of the THV terpolymer is significantly improved and a melting temperature of 226 °C can be achieved. Due to the higher dielectric constant of 3.6, the THV terpolymer shows 64% higher discharged energy density compared with BOPP. Its high melting temperature, low leakage current, high discharged energy density and high charge-discharge efficiency make THV potentially to be used as dielectric films for high-temperature and high-energy-density capacitive energy storage application.
