Abstract
The mechanism of electrical conduction in polyethersulfone (PES) is investigated through the thermally stimulated current (TSC), dc conduction current, and space charge distribution. PES has two TSC peaks below the glass transition temperature of 225/spl deg/C. The peak temperature of the lower-temperature TSC, /spl beta/, increases with an increase in the poling temperature. Through the measurements of space charge distribution by the pulsed electroacoustic method done in combination with the TSC measurements, /spl beta/ peak is considered to be due to ions. Furthermore, the dc conduction current obeys the ionic hopping conduction model, suggesting that the dominant carriers are ions.
