摘要 聚乳酸(PLA)是一类高分子聚酯,凡是能引起酯键断裂的因素都可以使聚乳酸发生降解。本文综述了聚乳酸(PLA)及其共聚物的化学降解、酶降解、超声波降解、辐射降解和微生物降解的体外降解方法及降解机理。 Poly(lactic acid) (PLA) is a kind of polyester. Its degradation is resulted from the cleavage of ester bond. In this article, the in vitro degradation methods such as chemistry, enzyme, ultrasonic, irradiation and microbe and their degradative mechanisms were introduced.
