Polylactide(PLA) is considered a good alternative to fossil fuelbased plastics as it is biodegradable andnontoxic to human. However PLA crystallize at a very low rate and has a relatively low melting temperature(Tm) in comparison with other commercial polymers. PLLA/PDLA stereocomplex has been expected to be potentially high-performance polymer, because it shows its Tm at 220℃ which is 50℃ higher than homo-PLA. In this work, Thermal properties and crystallization behaviors of stereocomplex were analyzed by using DSC(Differential Scanning Calorimetry), WAXD(Wide angle X-ray scattering) and Polarized microscope. |
