摘要
聚乳酸(PLA)是以玉米淀粉制得的乳酸为原料而合成得到的一种高分子材料,具有良好生物相容性、可生物降解性,较好的拉伸强度,但是其韧性较差而限制了其应用范围。本文综述了对其增韧改性的一些方法以及用于PLA增韧的一些改性助剂的性能及其用于PLA增韧改性的研究进展。
Poly （ lactic acid） （PLA） is a polymer which is synthesized from lactic acid obtained from corn starch. PLA shows good biocompatibility, biodegradability, and tensile strength, but poor toughness, which great- ly limits its application. In this paper, methods of toughening modification of PLA and the properties, research progress of toughening additives for PLA were reviewed.
