Abstract: In this paper,the influence of annealing process on the charge storage and stability in hybrid film electret PVDF/SiO2 was studied by means of surface potential decay and TSD-spectra. The properties of the film, before and after annealing, were discussed by means of infrared spectrum analysis. The experimental results show that electret properties of the sample were improved after annealing.

Key words: charge storage, annealing, charge stability, electret surface potential
