POLY 204 |
| In this study, poly(ε-caprolactone)-based polyurethane cationomer (PCL-PUC) containing 3 mol% of quaternary ammonium groups were synthesized and used as a matrix polymer of montmorillonite (MMT) nanocomposites. For all of the MMT/PCL-PUC nanocomposites, the MMT was successfully exfoliated and well dispersed in the PCL-PUC matrix up to 7 wt% of MMT. The phase separation of the MMT/PCL-PUC nanocomposites was retarded with increasing the content of MMT due to strong interactions between the PCL-PUC chains and the exfoliated MMT layers. The hydrolytic degradation of these nanocomposites was dramatically increased with increasing content of MMT. |
