Weak-field dielectric properties as a function of temperature at 1 kHz of pure terpolymer and its blends with different wt. % of P(VDF-TrFE).
Unipolar P-E loops of blends with different copolymer wt. % at room temperature under an electric field of 150 MV/m of 10 Hz. The inset shows (i) The polarization hysteresis of the P-E loops for the blends with different copolymer content and (ii) maximum polarizations of terpolymer and its blends measured at 10 Hz from 50 MV/m to 300 MV/m.
(a) Adiabatic temperature change as a function of electric field at room temperature. Error bars are indicated. (b) Adiabatic temperature changes as a function of temperature at 100 MV/m. Data points are shown and curves are drawn to guide eyes.
DSC traces of P(VDF-TrFE-CFE) terpolymer, P(VDF-TrFE) 55/45 copolymer and their blends.
Summary of XRD and DSC data of the blends.
