Abstract: The nano-composites of poly(lactic acid)/acetic starch/ organic montmorillonite (PLA/AS/OMMT) were prepared via extrusion melt intercalation. Thermal properties, rheological behavior and phase morphology of the nano-composites were analyzed using scanning calorimetry, dynamic rheometer, and scanning electron microscopy. It showed that OMMT increased the interaction between PLA and AS, inhibited the aggregation of AS, caused the decrease of particle size of AS. However, OMMT decreased Tg and Tc of the nano-composites.

Key words: poly(lactic acid), acetic starch, thermal property, phase morphology, rheological behavior, organic modified montmorillonite, nano-composite
