摘要
成核剂在改善聚乳酸(PLA)结晶性能中具有重要作用,本文介绍了PLA的结晶行为,综述了PLA用生物质成核剂的国内外研究进展,包括多糖类成核剂淀粉、纤维素、甲壳素、壳聚糖和环糊精,酚类成核剂木质素,醇类成核剂肌醇,蛋白质类成核剂氨基酸以及羧酸类成核剂乳清酸;其次,提出了目前生物质成核剂应用中存在的问题与改性方法;最后,展望了PLA生物质成核剂未来发展前景。
Nucleating agents play a very important role in the crystallization of polylactic acid(PLA).This paper introduced the crystallization mechanisms of PLA and the development status of biomass nucleating agents for PLA in China and overseas.These biomass nucleating agents included polysaccharide(starch,cellulose,chitin,chitosan and cyclodextrin),phenol(lignin),alcohol(inositol),protein(amino acid)and carboxylic acid(orotic acid).Furthermore,the problems in the applications of biomass nucleating agents for PLA were analyzed,and their development in the future was prospected.
