Study on the crystallization behaviors of polyethylene/MMT hybrid system

In this article, polyethylene/organic montmorillonite hybrid system was prepared by blending method in solution. And the microstructure of the system was characterized by WAXD and TEM. The crystallization behaviors of the system containing higher and lower contents of MMT were studied by DSC. Results indicate that MMT can be dispersed well in polyethylene matrix, and that both effects including nucleation and impeding chain diffusion can affect the crystallization process. Study on the confined crystallization behaviors of polyethylene under high MMT content shows that MMT can not change the crystalline type and cell dimension of polyethylene, however, the apparent crystallinity can be affected greatly under certain MMT contents.
