Assist Prof. Dr. Ghufran Muhammad Baqer, a lecturer at the Polymer Research Center, organized a seminar, entitled (Preparation and study of the optical and electrical properties of the composite polyaniline / Iraqi kaolin clay). She dealt with the methods of preparing polyaniline with Iraqi kaolin clay according to the (clay-polymer) system by the intercalation method, in which aniline is polymerized between the layers of kaolin with the help of an oxidizing agent by a mechanochemical method and in the presence of an ice bath at a temperature ranging from (0-5) °C, a dark green colored compound was obtained after washing with ammonia and then drying it, in order to pour samples for measurement. The compound was dissolved with the solvent and poured onto the slides prepared for measurement.
