Nonparametric dielectric response analysis with distribution of relaxation times

摘要: High temperature polymeric materials for electrical insulation and energy storage are needed transformational power applications such as pulsed-power hybrid vehicles. One of the candidate has been polyetherimide, an amorphous thermoplastic with a glass transition over 200 o C. Here, dielectric studies on material reported by taking into account polarization conduction processes in polyetherimide. The data were analyzed distribution relaxation times approach Debye expression kernel inversion algorithm, results then created map method satises Kramers-Kronig relationships, so ohmic conductivity permittivity at high frequencies could be estimated from experimental even there exists signicant measurement error. compared to published polyetherimide literature. is low loss polymer negligible losses below fragility was about 284 resolved using Vogel-Tammann-Fulcher expression. Polyetherimide good advanced technologies up
