STUDIES ON THE ELECTRONIC TRANSPORT PROPERTIES OF SOME AROMATIC POLYSULFONES IN THIN FILMS

摘要

The temperature dependences of electrical conductivity and the Seebeck coefficient for some new aromatic polysulfones are investigated. Measurements were performed using thin films deposited from the solution, and it was found that the polymers studied show semiconducting properties. Some correlation between these properties and the chemical structure and molecular weights of the polymers are established. The nature of the electrical conduction mechanism in the investigated polymers is discussed.
