Publikováno v: Journal of Experimental Nanoscience. 6:652-664

The electrical and thermal properties of thin films of polyimide/silica nanocomposites prepared via sol–gel process were studied as a function of nanosilica particles content, temperature and applied field frequency. It was found that the dielectri
