摘要
为降低聚乳酸(PLA)的成本、改善其亲水性、提高其力学性能和加工性能以及利用PLA改性其他高 分子,可使用基体扩链、表面改性、接枝、增塑、共混、复合等技术对PLA类生物降解材料进行改性。乳酸直接共聚合 改性、合成PLA类材料以及从廉价天然资源出发追求PLA改性的工业化是未来主要发展方向。
The technologies of chain extension, surface modification, grafting, plasticization, blending and compounding were used on the purpose of reducing production cost of poly(lactic acid) (PLA), improving its hy-drophilicity and raising its mechanical properties and processability. PLA was also taken as a modifier for other polymers. Direct copolymerization of lactic acid for modification and syntheses of PLA-like materials and industrialization of the modified PLA by taking cheap natural resources as starting substance are deemed as the main development trend of PLA in the future.
