Abstract
Untreated and annealed PVDF films in same crystalline phase were fabricated via different processes, and the effects of annealing treatment on the dielectric properties of PVDF films were studied. It has been found that the annealing treatment eliminates the micro pores in the PVDF films. As a result, the annealing treatment shows to exert strong influence on the relative permittivity and leakage current of PVDF films. Compared with common untreated PVDF film, the annealed PVDF film presents a higher relative permittivity about 8.7 in a 1 kHz electric field and a lower leakage current around 3.04 μA under a 1000 kV/cm electric field. However, the annealing treatment has little effect on the dissipation factor.
