功能分子共聚改性聚乳酸的研究进展

Research progress on the modification of poly(lactic acid) via copolymerization by functional molecules

为了获得降解性能、亲水性能和力学性能等更好的生物材料,各种功能分子改性聚乳酸的研究日益受到重视。本文按照官能团的不同,综述了近年来功能分子共聚改性聚乳酸的研究情况,指出利用新颖的功能分子改性聚乳酸和利用直接熔融共聚法降低共聚改性聚乳酸是未来的发展方向。

To get biomaterials with better biodegradability, hydrophilicity and mechanical property, more and more importance has been attached to the modification of poly（lactie acid） （PLA） by functional molecules. Classified as different functional group, the recent research progress on the modification of PLA via copolymerization by functional molecules was summarized. In the future, the modification of PLA by novel functional molecules via direct melt copolymerization should be the main development direction.
