Abstract

In order to meet the challenges of the harsh working conditions for capacitors at high temperatures (>150°C), dielectric polymers with high glass transition temperature (Tg) have been considered as the candidate for the next generation of film capacitors. In addition to high operating temperature, many efforts have been made in developing high dielectric constant and low loss in high Tg polymers. Recently, we report the finding that the dielectric constant of high Tg dielectric polymers can be increased markedly by very small amount of nanofiller loadings (< 1 vol%) without increasing the loss. In nanocomposites, it is well known that the interface effects between the polymer matrix and nanoparticles play important role in determining the performance. In this work, chemically modified nanoparticles are employed to investigate the interface effects of nanofillers in the enhancement of dielectric responses of these nanocomposites.
