Abstract

In the paper, polyimide/Multi-walled carbon nano-tubes hybrid films were prepared from polyamide acid precursor and Multi-walled carbon nano-tubes (MWNTs) through ultrasonic blending and in-situ polymerization. The surface morphology of the films was characterized by SEM. The influence of MWNTs on the electrical property was researched, which showed that with the increasing content of MWNTs, the volume resistivity declined. The corona-resistance of the hybrid films was higher than the pure polyimide films which time was 4h. When the doping content of MWNTs was near to 0.34wt%, the time of corona-resistance reached the maximum of 7.75h.
