摘要：

The electrical properties of polyimide based nanocomposites were fully investigated by isothermal steady-state current, dielectric spectroscopy, and thermally stimulated current measurements. The effect of nano fillers on the dielectric properties was evaluated via the interfacial polarization as well as the electrical conduction mechanism study. The electrical conduction of polyimide nanocomposites is found to be thermally assisted ionic in nature. The shift of the main thermally stimulated current peak to higher temperatures indicates deeper trapping by incorporating nano fillers. As a result, the nanocomposites will at least maintain the electrical breakdown strength because of the reduced electrical conductivity at elevated temperatures.
