this paper, Polyimide/nano-SiO2 composite films were prepared by means of ultrasonic mechanism. The corona-resistance of composite films were measured by high-voltage instrument which was assembled according to the international standard. The structure of the composite films were described by Fourier transform infrared analysis. The dispersion of the inorganic particles in the films, the morphology of the composite films before and after corona aging were characterized by atomic force microscopy. The results showed that it was effective for the dispersion of nano-SiO2 particles to use ultrasonic. Nanoparticles distributed uniformly in the polyimide matrix. Comparing with pure polyimide films, corona-resistance time of the composite films involved the particles less than 6wt%, was longer. The longest corona-resistance time of composite films reached four times than pure polyimide films.
