Poly (butylene succinate) (PBS)/ titanium silicate (TS-1) zeolite nanocomposites were prepared by in situ polymerization without conventional catalyst and were investigated thermal, mechanical and morphological properties. In this study, TS-1 zeolite was not only act as catalyst but also nucleating agent. TS-1 Zeolite contents in nanocomposites were 0.5 wt%, 1 wt%, 2 wt%, respectively. Crystallization behavior was measured by DSC. The PBS/TS-1 zeolite nanocomposites are higher crystallization temperature than Pure PBS. This result indicates that TS-1 zeolite enhances the crystallization rate of nanocomposites as nucleating agents. However, the increased zeolite contents are not directly proportion to crystallization rate. It was confirmed by WAXD and TEM micrograph that the dispersion of zeolite was efficiently dispersed in PBS, resulting mechanical properties were drastically increased. |
