摘　　要：聚乳酸是一种具有良好生物相容性、可生物降解的热塑性脂肪族聚脂,是一种环境友好材料。聚乳酸的结晶性能对其力学性能和降解速率有着重要的影响,因而其结晶行为也逐渐成为人们研究的热点。本文针对聚乳酸的结晶行为综述了聚乳酸及其共混、共聚体系的最新研究进展。Poly （lactic acid） （PLA） is a biocompatible and biodegradable linear aliphatic thermoplastic and environmentally benign material. The crystallinity of PLA has great influence on its mechanical properties and degradation rate, so the crystallization behavior of PLA has also attracted many researchers to widely research. In this paper, the progress of PLA and its blends and copolymers was reviewed based on the crystallization behavior
