共混聚合物/碳纳米管改性聚乳酸(PLA)复合物的研究进展

Research progress of modified poly(lactic acid)(PLA)by blending polymer/carbon nanotubes composite

简述了聚合物改性聚乳酸(PLA)的方法,可以通过添加小分子增塑剂或可生物降解聚合物改性PLA的脆性,进一步就多元共混体系特别是可生物降解的共混聚合物中引入碳纳米管改进共混聚合物的相容性进行了介绍,对共混聚合物/碳纳米管复合材料在流变性能方面的研究进行了综述,并对共混聚合物/碳纳米管改性聚乳酸(PLA)复合物未来的发展方向提出了几点建议。

The preparation methods of polymer/carbon nanotubes composite, the modification of PLA with small molecules plasticizers and biodegradable polymer were reviewed. The rheological properties research progress of blending polymers/carbon nanotubes composite also further clarified, provided scientific guidance and theoretical basis for using physical blending method modified the PLA performance and expanded the applications of bio-based polymer nanocompos- ites. Some development suggestions of PLA blends were pointed put finally.
