N2 - The increased functionality and miniaturization of the modern electronic and electric systems, and needs for operation at high temperatures (> 150 °C) require the development of high temperature polymer capacitors. However, at high temperatures, the present polymer dielectrics cannot deliver a large discharged energy density. This is caused by a large conduction loss at high electric field and high temperature. Here, we present our recent study, revealing that in high temperature (high glass transition, Tg) dipolar polymers, adding a small amount of nanofillers (< 1 volume %) can greatly enhance the discharged energy density. Several types of high Tg polymers, including Polyimide (PI), Polyetherimide (PEI), Polyaromatic ether ketone (PAEK), and Polyarylene methyl ether urea (PEMEU) were selected for the study.
