Electrical conduction characteristics of the PE/ionomer blends, i.e., PE/Surlyn 1652 blends and PE/Surlyn 1601 blends, have been investigated. It has been found that the SCLC mechanism works over the range of electric field of 10 to 400 kV/cm at several temperatures up to 100℃' for both blends. Higher conduction currents at low fields and lower conduction currents at high fields have been observed in PE/Surlyn 1601 blends than in PE/Surlyn 1652 blends. In the case of PE/Surlyn 1601 blends, conduction currents decrease as the Surlyn 1601 contents increase at high fields. The two features were explained in terms of the effective charge mobility. These observations indicate that the charges tend to be trapped in PE/Surlyn 1601 blends and conducted by a hopping mechanism in PE/Surlyn 1652 blends, which can be attributed to the differences in the nature of ionic clusters in both ionomers.
