英文摘要The influence of stretching under different temperatures on the crystallization behavior of poly( L-lactic acid) (PLLA) was investigated by the combinational investigation of Frill, DSc, and XRD It was found that stretching could remarkably improve the crystallization rate and crystallinity of PLLA Stretched at a draw ratio of 3, PLLA forms alpha-form crystals in the temperature range of 90-95 degrees C. Further increasing the draw ratio, the crystallinity remains almost constant. With increasing the stretching temperature up to 105 degrees C, the PLLA films cannot crystallize under stretching. Contrary to the unstretched PLLA film, the stretched PLLA films gradually crystallize during the heating process, indicating that pre-stretching can change the crystallization behavior of PLLA.
