Electrical properties of modified polyvinyl alcohol conjugates and doped modified polyvinyl alcohol conjugates

Abstract

The electrical properties modified polyvinyl alcohol conjugates and doped modified polyvinyl alcohol samples were studied. The electrical conductivity of all the MPVA and DMPVA show a tendency to increase by increasing the temperature upto 403 K and obeys log s vs. 1/T relation indicating their semiconducting behavior. The variation in the electrical conductivity and activation energy of electrical conduction with the metal ions in DMPVA may be explained on the basis of influence of the incorporation of different metal ions in the MPVAs, which increases the ionization tendency.
