Abstract :
With the development of modern technology, the working condition for insulating materials has become even severer. Electrical insulating materials are demanded to have even higher reliability. Good thermal endurance has also become very important in recent years. Polyethersulfone (PES) is a new engineering thermoplastic material which can be used continuously at 180°C thanks to its high glass transition temperature of 225°C. It also has the highest-class resistance for chemicals among amorphous polymers. Therefore, PES is expected to be applied in electrical insulation as well as in various other industrial fields. In this paper, dominant conduction carriers in polyethersulfone are discussed through the experimental results obtained mainly by the thermally stimulated discharging current (TSC) and dc conduction current
