Electrical conduction of PPS films has been investigated in the range of 100-160°C. The results obtained manifests three characteristics dependence on the electric field: low field (0-0.2MV/cm), medium field (0.2-0.6MV/cm) and high field (0.6-1.6MV/cm). No dependence of electrical conduction on electrode materials was obtained in the low and medium electric field regions. The current increses with electric field superlinearly in the medium field region, and ionic hopping has been proposed as the dominant mechanism.
The explicit dependence on electrode materials has been obtained in the high field region, where Au electrode gives larger current than Al electrode. That is, as the current show the dependence on the pos-itive electrode material, hole injection is taken into account for the discussion of the conduction mechanism.
