摘要

聚乳酸(PLA)类材料以其独特的生物相容性和生物可降解性备受关注.将其两种旋光对映体

即PLLA与PDLA共混

会产生一种具有更高熔点的立体复合物(sc-PLA)

并能提高聚合物的结晶度、结晶速率以及耐热性

对于PLA类材料的开发和应用具有重要意义.本文从结晶机理、球晶形态、热稳定性和降解性能等方面综述了近年来有关sc-PLA结构与性能的研究进展

并对sc-PLA研究方向提出了作者的观点。

Abstract

Absrtact: Much attention has been paid to poly(lactic acid) (PLA) due to its biodegradability and biocompatibility. Stereocomplexed PLA (sc-PLA)

prepared through solution or melt-blending PLLA and PDLA

show higher melt temperature (

). In addition

the stereocomplexation structure leads to improvements on crystallinity

rate of crystallization

and heat resistance of PLLA and/or PDLA. The review gives an introduction on the research development related to the sc-PLA

focusing on crystallization mechanism

spherulites morphology

thermal stability and biodegradability

etc. Finally

a simple research prospect on sc-PLA is shown from the views of the authors.
