摘要:
为增强聚乳酸/聚对苯二甲酸己二酸丁二酯（PLA/PBAT）共混体系的相容性并提高PLA/PBAT共混材料的冲击强度和拉伸韧性，制备了PBAT接枝苯乙烯 甲基丙烯酸缩水甘油酯梳状共聚物（BSGE）反应性增容剂，进一步通过反应性挤出的方式制备得到改性PLA/PBAT共混材料。采用核磁共振波谱仪、傅里叶红外光谱仪、旋转流变仪和扫描电子显微镜分析BSGE对PLA/PBAT共混材料的化学结构、流变特性及微观形貌的影响，并通过差示扫描量热仪表征改性PLA/PBAT共混材料热性能，通过万能材料试验机和摆锤冲击试验机测试改性PLA/PBAT共混材料力学性能。结果表明：加入BSGE后，PLA/PBAT共混材料内部形成了双接枝共聚物，双组分共混物的相区结构由明显的海岛结构转变为共连续相结构，界面相容性得到明显改善，且断裂伸长率和冲击强度分别达到了346 2%和35 kJ/m 2，力学性能优异，应力在材料内得以有效传递，充分发挥了PBAT的增韧效果。该研究可为开发高性能PLA/PBAT可降解共混材料提供了理论依据。
