Abstract
The crystal structure shows great influence on dielectric and energy storage performance of poly(vinylidene fluoride) (PVDF) films. In this paper, a γ-phase PVDF film was fabricated by crystallization of PVDF from a DMF solution through a solution-casting method and a quenching treatment. The influences of crystalline phases on the dielectric and energy storage properties of the films were studied. It has been found that, compared with common α- and β-phase, the obtained γ-phase PVDF film presents much higher relative permittivity of about 9.8 in a 1 kHz electric field. The ferroelectric hysteresis loop investigation indicates that the γ-phase PVDF film exhibits much slimmer polarization–electric field hysteresis loops than α- and β-phase PVDF films and a high energy efficiency more than 72 % is obtained. This γ-phase PVDF film also shows low leakage current at high working voltage, which is more desirable and promising for high performance pulse discharge capacitor application.
