Effective Preparation and Characterization of Montmorillonite/Poly(ε-caprolactone)-based Polyurethane Nanocomposites |
초록 |
In this study, montmorillonite (MMT)/poly(ε-caprolactone)-based polyurethane cationomer (MMT/PCL-PUC) nanocomposites were prepared and their mechanical properties, thermal stabilities, and biodegradability were investigated. The PCL-PUC have 3 mol% of quaternary ammonium groups in the main chain. The MMT was successfully exfoliated and well dispersed in the PCL-PUC matrix up to 7 wt% of MMT. As the content of MMT increased in the MMT/PCL-PUC nanocomposites, the degree of microphase separation of the PCL-PUC decreased due to the strong interactions between the PCL-PUC chains and the exfoliated MMT layers. Biodegradability of the MMT/PCL-PUC nanocomposites was dramatically increased with increasing content of MMT likely due to the less phase-separated morphologies of the MMT/PCL-PUC. |
