聚乳酸结晶成核剂的研究进展

摘要

聚乳酸作为一种新型可生物降解高分子材料,具有优良的机械性能和生物降解性,但结晶速度缓慢也制约了其应用,添加结晶成核剂是一种改善聚合物结晶行为的有效手段,本文综述近年国内外对聚乳酸结晶成核剂的研究情况。%As a new biodegradable polymer material,poly（lactic acid） has good mechanical and biodegradable performances,but the slow crystallization velocity restricts its application.Adding nucleating agent is a effective method to modify the crystallation behavior of polymer.In this paper,the research progress on nucleating agent used for poly（lactic acid） was reviewed.
