FIG. 1.

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).

Image of FIG. 2.
FIG. 2.

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.
