Abstract

In order to investigate the roles of inorganic nanoparticles on improving breakdown behavior of Al₂O₃/PI film, the DC breakdown characteristics were studied in this paper. The morphology and element distribution of zones near the breakdown holes were observed by SEM and electron spectroscope for both the original PI film and Al₂O₃/PI nanocomposite film. The experimental results showed that the electrical breakdown strength was enhanced significantly for the sample with 5% Al₂O₃ content. The damaged region of breakdown hole for PI is larger than that of Al₂O₃/PI nanocomposite and PI film were much more seriously destroyed. There are larger distinctness for the distribution of C and O elements in zones near breakdown holes for both PI and Al₂O₃/PI nanocomposite films.
