| 摘 要： | 制备了高填充的甘油塑化淀粉（GTPS）/聚丁二酸丁二醇酯（PBS）合金，并对其结构性能进行了表征。结果表明：GTPS/PBS在合金加工过程中其扭矩以及力学性能随PBS质量分数的增加及甘油质量分数的减小而增大；扫描电镜（SEM）显示甘油可提高合金的相容性；动态力学分析（DMA）表明合金在玻璃态时的储存模量高于纯PBS，黏流态时则相反；合金的热稳定性随PBS和甘油质量分数的增加而有所提高；PBS的加入将合金的吸水率由100%以上降低到10%以下；淀粉和甘油的存在则均可提高PBS的降解率。

| Abstract: | Thermoplastic starch plasticised by glycerol (GTPS) /poly(butylene-succinate) (PBS) blends were prepared using glycerol as the plasticizer. Besides, structure and performance of the blends were also characterized. Results showed that during processing the torque of GTPS/PBS blends and mechanical properties increased with the rising of PBS mass fraction and the decreasing of glycerol mass fraction. Scanning electron microscope (SEM) showed that more glycerol would improve the compatibility of the blends. Dynamic mechanical analysis (DMA) results suggested that storage modulus of blends in glassy state was higher than PBS, but conversely in rubbery state. Furthermore, the blends with higher PBS and glycerol mass fraction exhibited better thermal stability. Absorption rate decreased from more than 100% to less than 10% by adding PBS. Both starch and glycerol could improve the biodegradation rate of PBS. |
