Notes:
Polymer nanocomposites are recognized as the next generation of polymer compositesdue to their exceptional properties. Understanding the molecular origin of the reinforcementmechanism is crucial to the development of such promising materials. This paper reports our recentmolecular dynamic study on clay-based polyurethane nanocomposites. The effect of clay plateletson phase separation behavior of polyurethane, at the clay-polyurethane interface, is quantified interms of molecular interactions, structure and dynamics. The results show that the nanoconfinementof polyurethane chains in clay gallery impedes the development of phase separationcommonly observed in bulk polyurethane. The absence of phase separation of intercalatedpolyurethane is believed to be related to the competitive interactions among clay platelet,polyurethane and surfactant
