摘要：

Poly(epsilon-caprolactone) (PCL)/montmorillonite (MMT) nanocomposites were prepared by in situ ring-opening polymerization of epsilon-caprolactone in the presence of MMT modified by hydroxyl-group containing alkylammonium cation (Cloisite (R) 30B) in a microwave oven. For the polymerization mixtures, plateaus or exothermal peaks were observed in their temperature-time profiles and can be attributed to the heat-generating nature of the ring-opening polymerization. The morphologies of the nanocomposites showed a predominantly exfoliated structure. The mechanical properties of the nanocomposites were evaluated via dynamic mechanical analysis. Compared with that of the recovered PCL matrix, the mechanical properties of the PCL/Cloisite (R) 30B nanocomposites showed obvious improvement.
