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.
