Electrical properties of polyetherimide thin films: Nonparametric dielectric reponse analysis with distribution of relaxation times

Abstract

High temperature polymeric materials for electrical insulation and energy storage are needed for transformational power applications such as pulsed-power and hyrid electrical vehicles. One of the candidate materials has been polyetherimide, an amourphous thermoplastic with a glass transition over 200C. Here dielectric studies on the material are reported by taking into account the polarization and conduction processes in the polyetherimide.
