Carbon nanotube (CNT) reinforced polylactide (PLA) nanocomposites were prepared using a melt compounding process. The isothermal crystallization kinetic of PLA/CNT nanocomposites according to Avrami’s theory was analyzed. The incorporation of CNT improved effectively the crystallization rate of PLA/CNT nanocomposites through heterogeneous nucleation. The nucleating effect of CNTs was confirmed using polarized optical microscopy. Furthermore, the tensile strength/modulus and thermal stability of PLA/CNT nanocomposites were enhanced when a very small quantity of CNT was added. This research investigated to the effect of CNTs, which significantly influenced the isothermal behavior, thermal stability, mechanical, and rheological properties of the PLA/CNT nanocomposites, providing a design guide for PLA/CNT nanocomposites in industrial fields. This research was supported by National Research Foundation of Korea. (Project No. 2010-0028182). |
