Abstract
Modified masterbatch method comprising of the wet kneading and intercalated modifiers process was successfully applied to prepare exfoliated polylactic acid (PLA) clay hybrids. The crystallization rate of PLA/clay nanocomposite was improved by introducing alkylamide, an intercalated modifier with higher crystallinity. Both XRD and TEM analyses showed that the exfoliated and partially intercalated PLA nanocomposites can be obtained. The effect of clay and intercalated modifier on the nonisothermal, isothermal crystallization kinetics, and morphology of PLA was investigated using DSC instrument. The PLA nanocomposites showed faster crystallization rate because the alkylamide modifier act as a nucleation agent that successfully promoted crystallization. Notably, the crystallinity of PLA/clay hybrids dramatically increased from 9.0 to 42.1 %. The nucleation and crystal growth rate of PLA when crystallized from melt state is greatly influenced by the presence of organoclays. Therefore, as revealed from this isothermal crystallization investigation, the crystallization rate is enhanced by a factor of about 7-17.
