Since polymeric materials have many superior properties, they are inevitable materials for the spacecraft. The space environment, however, is so severe for the spacecraft because the temperature changes drastically from - 150 to 120 C and the high energy charged particles are scattered. The polymers sometimes have serious damage by irradiation of high energy charged particles. When the polymers of the spacecraft are irradiated by high energy charged particles, some of injected charges accumulate and remain for long time in the bulk of the polymers. Since the bulk charges sometimes cause the degradation or breakdown of the materials, the investigation of the charging and decay processes in the polymeric materials at various temperatures are important to decide an adequate material for the spacecraft. In this report, we observed the decay processes of accumulated charge in e-beam irradiated polymers, such as Polyimide or Polystyrene, during elevating temperature using pulsed electro-acoustic method.
