Abstract
The complex dielectric permittivity of vinylidene fluoride-trifluoroethylene copolymer with 20 mol% of TrFE [P(VDF-TrFE) 80/20] has been measured over the frequency range of 500 kHz to 20 MHz at temperatures varying from 20° to 100 °C. This copolymer has the highest electromechanical coupling coefficient ktamong all TrFE compositions and has thus attracted considerable interest in ultrasonic transducer applications. The effect of dielectric relaxation on the performance of VDF-TrFE transducers is discussed.
