摘　　要：PLA/starch复合材料作为生物高分子复合材料可生物降解,但其界面相容性差,影响机械性能。目前改善PLA/starch、PLA/TPS相容性有3种方法:1)增塑剂改性;2)交联剂改性;3)接枝共聚物改性。综述了PLA/starch改善界面相容性的研究进展,并阐述了PLA/starch前景与发展方向。PLA/starch as a biological biodegradable polymer composite have many advantages, such as low cost, but the poor interface compatibility affecte mechanical properties. At present, PLA/starch, PLA/TPS compatibility are improved in three ways of plasticizer modified, crosslinker modified, and graft copolymer modified. The methods of improving interface compatibility of PLA/starch are introduled and the PLA/starch prospects and development are described.
