摘　　要：聚乳酸(PLA)是一种热塑性脂肪族聚酯,其性能优越,被广泛应用,但脆性大、韧性差的缺点,极大的阻碍了它的应用范围,所以如何将聚乳酸进行良好的增韧改性成为科学家的主要研究课题。本文综述了采用物理改性(添加增塑剂改性、共混改性)的方法来对聚乳酸增韧的最新科学研究进展。Polylactic acid(PLA)is a thermoplastic aliphatic polyester,which has superior properties and is widely used.However,its brittleness and poor toughness greatly hinder its application range,so how to toughen PLA has become the main research topic of scientists.In this paper,the latest scientific research progress of toughening PLA by physical modification(adding plasticizer and blending modification)is reviewed.

关 键 词：聚乳酸 增韧 物理改性 研究进展
