Sulfonated poly(ether ether sulfones) Characterization and study of dielectrical properties by impedance spectroscopy

摘要

In this work, three samples of sulfonated polysulfones of different sulfonation degree have been charactrized, and the electrical properties of dense membranes based on them have been evaluated. The polymers were characterized spectroscopically, and by their inherent viscosity, and water absorption. Electrical characterization of membranes was carried out on dense membranes in contact with NaCl solution, by impedance spectroscopy (IS) measurements using equivalent circuits as models.
