Nanohybrid polymers have many excellent properties, such as high dielectric constant, high dielectric strength and low loss and so on, which apply in the electricity and electron fields widely. In this paper, the nanohybrid Al2O3/PI films were prepared by Sol-Gel process, then, Au and Al were sputtered on the films surface respectively as electrode. The dielectric properties (dielectric constant,...
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...
Inorganic nanohybrid polyimide (PI) film has great potential for applications in the areas of electrics and electronics because of its excellent electrical performance, such as the resistance to aging and corona and so on. The breakdown strength of insulating materials is generally measured by DC, AC or impulse voltage. However, the influence of laser irradiation to Al2O3/ PI film has not been reported...
