Abstract

Conduction characteristics of polyetherimide (PEI) were investigated at the electric fields of 0.9-27 MV/m and the temperatures of 50-100°C. It was found that the current densities of PEI increased with the increase of the electric field and the temperature and that the conduction of PEI was governed by the thermally activated ionic hopping process. The hopping distance of ions in the PEI decreased from 5.69 nm at 50°C to 3.34 nm at 100°C, which was attributed to the increase of molecular motions with the increase of temperature. The activation energy for the conduction was calculated to be 0.74 eV.
