摘　　要：聚乳酸是一种可生物降解的高分子绿色材料,综述了聚乳酸的基本性能和近年来聚乳酸膜制备方法的研究进展,包括热致相分离法、浸没沉淀相转化法和静电纺丝法;聚乳酸固有的脆性严重阻碍其在分离膜中的应用,需要对其进行增韧改性,主要介绍了化学改性和物理改性两种方法;最后指出了聚乳酸膜增韧改性的研究方向和重点。Poly(lactic acid)is biodegradable and green polymer material.The basic properties of poly(lactic acid)and the recent research progress on the preparation of poly(lactic acid)membranes were reviewed,including thermally induced phase separation,immersion precipitation phase conversion,electrostatic spinning,etc.Due to its inherent brittleness seriously hindered its application in membranes,introduced systematically chemical and physical modifications to toughen the poly(lactic acid)membranes.Finally,the research direction and emphases of toughening modification of PLA membranes were pointed out.
