Abstract
Polyvinylidene fluoride-trifluoroethylene [P(VDF-TrFE) 70/30 mol%] copolymer can be transformed from a ferroelectric to a relaxor material after proton irradiation. The phase transition peak broadens and shifts towards lower temperature as the measurement frequency decreases. In the present study, 0-3 composites are fabricated by incorporating 0.9Pb(Mg1/3Nb2/3)O3-0.1PbTiO3 ceramic powder into a P(VDF-TrFE) 70/30 mol% copolymer matrix. 0.9PMN-0.1PT ceramic is a relaxor ferroelectric with high dielectric permittivity. It was found that the relative permittivity of PMN-PT/P(VDF-TrFE) 0-3 composite increases with increasing ceramic volume fraction. Composites with 0.3 and 0.4 volume fraction of 0.9PMN-0.1PT were subjected to proton irradiation. With a 80 Mrad (4.76 × 1013 ions/cm2) proton dosage, the relative permittivity of the 0.4 volume fraction 0-3 composites can go up to 130 near room temperature (at 1kHz).
