聚乳酸共混体系的研究进展

Review of Poly(lactic acid) Based Blends

聚乳酸是人工合成的可生物降解的热塑性脂肪族聚酯 ,是一种环境友好的材料 ,逐渐成为人们研究的热点。本文根据聚乳酸共混体系中另一组分的生物降解性 ,将聚乳酸共混体系分为完全可生物降解共混体系和部分可生物降解共混体系两类。针对体系的相容性和结晶结构以及在提高PLA的性能和降低成本等方面 .综述了聚乳酸共混体系的最新研究进展 。

Poly(lactic acid) was linear aliphatic thermoplastic polyester and environmentally benign material, which attracts many researchers to widely research.In this paper, according to the biodegradable properties of the other composition in the blends, poly(lactic acid) blends were divided into two varieties of fully biodegradable blends and partially biodegradable blends. And the progress of poly(lactic acid) blends was reviewed, based on the miscibility, the crystal structures, the improvements of properties and the lowered costs, etc. Their advance in the future was also introduced briefly.
