摘要

采用熔融接枝法分别制备马来酸酐接枝聚乳酸、甲基丙烯酸缩水甘油酯接枝聚乳酸和马来酸酐/甲基丙烯酸缩水甘油酯共接枝聚乳酸，并利用红外光谱对接枝共聚物进行结构表征。分别以三种接枝共聚物为相容剂，采用注塑成型制备了木粉/PLA复合材料。利用扫描电子显微镜（SEM）对复合材料的断面形貌进行微观分析，结果表明，加入不同接枝共聚物后木粉/PLA复合材料两相看不出明显相界面，界面相容性得到改善。对不同接枝共聚物制备的复合材料的力学性能、加工流动性能和动态流变性能测定的结果显示，加入MAH/GMA共接枝聚乳酸后的木粉/PLA复合材料和未添加相容剂的复合材料相比，拉伸强度和冲击强度分别提高了9.54%和7.23%，复合体系的平衡扭矩和剪切热提高，储能模量及复数黏度均增大。

Abstract：

Graft copolymers of PLA-g-MAH, PLA-g-GMA and PLA-co-MAH/GMA were prepared by means of melt grafting. The structure of the graft copolymers were characterized by FTIR.Wood flour/PLA composites were prepared by injection molding with three kinds of graft copolymers as compatibilizers, and the fractured morphology of composites was investigated by scanning electron microscope (SEM). Results show that there is no obvious phase interface between wood flour and PLA, which indicating the interfacial compatibility of wood flour/PLA composites is improved after adding different graft copolymers. The determination results of mechanical properties, processing flowability and dynamic rheological property of composites prepared with different graft copolymers reveal that, compared to the composite without compatibilizer, the tensile strength and impact strength of wood flour/PLA composites are increased by 9.54% and 7.23% respectively, and the equilibrium torque, shear heat, storage modulus and complex viscosity are all increased after adding maleic anhydride/glycidyl methacrylate cografted polylactic acid.

Key words： polylactic acid maleic anhydride glycidyl methacrylate PLA grafted copolymer compati-bility
