聚碳酸亚丙酯/聚乳酸共混物性能研究进展

摘要

This paper reported an overview for the research progress in poly(propylene carbonate) (PPC)/poly (lactic acid) (PLA) blends.The compatibility,mechanical properties,thermal stability and degradability of PPC/PLA blends were introduced,and their degradation mechanisms were briefly presented.Application prospects and characterization methods of PPC/PLA blends were also recommended.%概述了聚碳酸亚丙酯/聚乳酸(PPC/PLA)共混物性能的研究进展,从共混物的相容性、力学性能、热稳定性能及降解性能等方面介绍了相关研究成果及表征方法,并阐明了PPC和PLA降解机理.最后,对可完全降解的PPC/PLA共混物的应用前景及表征方法提出了意见.
