Abstract

Dielectric polymer film capacitor with high energy density and efficiency is one of the enabling technologies for the development of flexible electronics and power systems. Herein, we introduce wide-bandgap inorganic fillers into the polymer matrices to yield polymer nanocomposites. It is found that the leakage current is largely decreased, and the charge-discharge efficiency is significantly improved of the nanocomposites, especially at high fields and elevated temperatures, compared to polymer matrices. The increase in activation energy indicates that the presence of wide-bandgap nanofillers in the polymer matrix gives rise to a higher barrier to be overcome for occurring conduction processes. In addition, a strong dependence of high-field conduction behavior on the filler morphology is revealed. Compared to zero- and one-dimensional fillers, two-dimensional nanoplate enables the shortest hopping distance, and is the most efficient in inhibiting conduction loss of the polymer composites.
