MODIFICATION OF CLAY INTERCALATE STRUCTURE AND PROPERTIES OF TPO BASED NANOCOMPOSITES

摘要

Intercalated montmorillonite (MMT) is the most important organoclay for production of polymer/clay nanocomposites. Understanding the structure-properties relationship is crucial for the successful development of new materials based on organically modified clays. Structure analysis based on X-ray diffraction and computational molecular modeling reveals details of Na-MMT intercalated with octadecylamine. Properties of polypropylene and polyethylene nanocomposite films prepared from clays intercalated with octadecylamine by ion-dipole method and with alkylammonium organocations intercalated by more conventional ion-exchange method are discussed.
