摘　　要：聚乳酸(PLA)是一种具有生物降解性、生物相容性和无毒的聚合物。其具有较低的加工成本及理想的机械性能,被认为是具有良好生物医学应用和替代石油基的聚合物。但其低的韧性,限制其广泛的应用。对近年来聚乳酸的增韧方法进行了综述,并对其发展方向进行了展望。Polylactide(PLA)is a biodegradable,biocompatible and non-toxic polymer.Due to its low processing cost and desirable mechanical properties,it is considered as a polymer with good biomedical applications and an alternative to petroleum based polymers.However,its low toughness limits its wide application.The toughening methods of PLA in recent years were reviewed,and prospected the development direction of PLA.
