Abstract
Poly(L-lactic acid) (PLLA)/1,2,3-benzotriazole (BTA) composites were fabricated by melt blending and hot-press forming process. The melting behavior of stretched PLLA/2 % BTA composities was investigated by differential scanning calorimetry. The results showed that stretching could improve the crystallization ability of poly(L-lactic acid) and stretching made crystallization peak of poly(L-lactic acid) become sharper and the high-temperature melting peak become more obvious. Addition of 1,2,3-benzotriazole also could improve the crystallization of poly(L-lactic acid). However, the crystallization peak of stretched PLLA/2 % BTA samples became weak. Melting behavior of stretched PLLA/BTA samples was similar to that of PLLA/ BTA, the low-temperature melting peak shifted to higher temperature with increasing of crystallization temperature. However, the high-temperature melting peak almost did not move.
