Isothermal Crystallization Behavior and Mechanical Properties of Polylactide/Carbon Nanotube Nanocomposites |
| 초록 |
Carbon nanotube (CNT) reinforced polylactide (PLA) nanocomposites were prepared by melt compounding process using a Hakke twin screw extruder. The isothermal crystallization kinetics of PLA/CNT nanocomposites were investigated by polarized optical microscope and differential scanning calorimetry in the temperature range of 90-120oC. The incorporation of CNT improved effectively the crystallinity and crystallization rates of PLA/CNT nanocomposites through heterogeneous nucleation. The slope of the plot of log G’ versus log G’’ for the PLA/CNT nanocomposites was decreased with increasing CNT content indicating increase of heterogeneity and occurrence of significant structural change during melt compounding process. In addition, tensile strength and modulus of PLA/CNT nanocomposites were enhanced as CNT content increased because of reinforcing effect of CNT with high aspect ratio. This research was supported by National Research Foundation of Korea. (Project No. 2010-0028182). |
