Abstract
This thesis is devoted to investigate the structure-property relationships in some polymer and some polymer-metal salt complex system. Polyvinyl alcohol PVA and ethylene-venyl alcohol (EVA) copolymers were used in this study. Different compositions have been prepared by casting technique. Morphological micro structure of the films, mechanical, electrical, and optical properties in correlation to the structure of the metal ions containing-polymers were carried out.
