摘　　要：通过力学性能测试、SEM和DSC分析,研究了马来酸酐接枝乙烯-1-辛烯共聚物(POE-g-MAH)对聚丙烯(PP)/聚酰胺6(PA6)/纳米TiO2复合材料的相容性和力学性能的影响。结果表明:POE-g-MAH显著改善了PP/PA6/纳米TiO2复合材料的相容性,使复合材料在保持与纯PP相当的拉伸强度和弯曲强度的同时,大幅度地提高了其缺口冲击强度和断裂伸长率;PA6对PP基体有异相成核作用,POE-g-MAH的加入进一步促进了这种异相成核作用。The Effects of compatilizer POE-g-MAH on compatibility and mechanical properties of PP/ PA6/nano-TiO2 composite were studied by means of mechanical property test,SEM and DSC analysis.The results show that：the addition of POE-g-MAH improves the compatibility of PP/PA6/nano-TiO2 composite remarkably,and increases the impact strength and elongation at break obviously;both PA6 and POE-g-MAH promote the heterogeneous nucleation of PP matrix.
