摘要:
In this research, organo-montmorillonite (OMMT) was synthesized by ion exchange technology, Then the poly(L-lactic acid)(PLLA)/OMMT composites were fabricated using melt blending and hot-press forming. The isothermal crystallization behavior of PLLA/OMMT composites was investigated in detail and isothermal crystllization behavior was affected by crystallization temperature and organomontmorillonite content. Compared to the neat poly(L-lactic acid), the half-time of poly(L-lactic acid) with 5 % organo-montmorillonite decreases from 2991.5s to 327s. and the kinetic of isothermal crystallization of PLLA/OMMT was described by Avrami theory and the results showed that PLLA/OMMT composite had complicated nucleation mechanism.
