绿色化学结构单元乳酸/聚乳酸研究进展

Recent development of the lactic acid/PLA

乳酸是绿色化学的基本结构单元之一,主要应用于食品保健、医药卫生和工业等方面。聚乳酸是以乳酸为主要原料的聚合物。介绍了聚乳酸共混、共聚,特别是立构复合等改性方法。综述了聚乳酸在可降解塑料、纤维、医用材料、农用地膜和纺织等领域的应用,并对其发展方向进行了展望。

The lactic acid is one of the building blocks in green chemistry and the best available in food and health care,medical and industry.polylactive（PLA） is one of the most important bioplastics.The modification methods of PLA such as blending,copolymerization,stereocomplex（SC） is introduced.Application field of PLA in bio-degradable plastics and fiber,agricultural film,biomedical and textile is summarized.And the current research and the development trends of polylactide in future are reviewed.
