Manufacturing Polyurethane-Clay Nanocomposite inPresence of Liquid Phase Catalyst and Examining ItsMechanical, Rheological, and Thermal Properties

In this research, nanocomposite was synthetized based on MMT/PU double layer nano-clay. The nano-clay gave good properties to polyurethane by cationic and anionic factors and ion exchange process and has good compatibility with polyurethane. The connection between nan-clay and polymer was covalent bond and the reaction was in situ polymerization. Reactor was used for nano-clay distribution in polyol. The rheological results showed that the synthetized nanocomposite with 0.2 and 0.5 nano-clay made acceptable polymer. Nanocomposites containing 0.2% nano had better stress and strain. The cohesion results showed increasing bond power between two polymeric layers in presence of nano-claythan layers without nano-clay
