Research Advance in Degradability of Biodegradable Polymer Nanocomposites

可生物降解聚合物中的层状硅酸盐纳米复合材料,可极大提高其力学性能,但同时会影响到材料的降解速率。研究纳米填料对可生物降解聚合物降解速率的影响及降解机理的变化,可拓宽其应用领域。综述聚乳酸(PLA)、淀粉、聚己内酯(PCL)、纤维素、聚羟基烷脂肪酸酯(PHA)、聚琥珀酸丁二醇酯(PBS)等可生物降解聚合物基层状硅酸盐纳米复合材料制备及降解性能研究现状及进展。

Layered silicate nanocomposites of biodegradable polymers can greatly increase mechanical properties of the polymers, which have influence on the degradable rates of the polymers. The researches on the effects of nano-flllers on the degradable rates and mechanisms of the biodegradable polymers can extend their application areas. The preparation, degradability study situation and advance of the layered silicate nanocomposites of biodegradable polymers such as poly（lactic acid） （PLA）, starch, poly（caprolactone）（PCL）, polyhvdroxYalkanoate （PHA）. cellulose, poly（butvlene succinate） （PBS）. and so on are reviewed.
