| 摘 要： | 以环氧类增容剂(REC)为增容剂，采用双螺杆挤出机熔融共混制备聚乳酸(PLA)/聚对苯二甲酸己二酸丁二醇酯(PBAT)共混物。研究了增容剂对共混体系微观结构、力学性能和热性能的影响。结果表明，添加适量REC可以提高PLA与PBAT的相容性,改善PLA/PBAT共混体系的综合力学性能；REC用量为1.4份时共混体系呈现出良好的相容性，此时共混物冲击强度由268 kJ/m2增加到621 kJ/m2、断裂伸长率提高由222 %增加到357 %。

| Abstract: | An epoxy resin was introduced into PLA/PBAT blends as a compatibilizer by melt blending using a twin screw extruder. The effect of the compatihilizer on thermal performance, mechanical properties, and microstructure of PLA/PBAT blends were investigated. It showed that the interface bonding force in the blends was enhanced by the compatibilizer, and the comprehensive mechanical properties of the blend were increased greatly. An inclusion of 14 phr compatibilizer increased the impact strength and elongation at break from 268 kJ/m2 to 621 kJ/m2 and 222 % to 357 %, respectively. |
