摘要：以马来酸酐接枝聚丙烯(PP-g-MAH)为增容剂,采用熔融挤出-热拉伸法制备了聚丙烯(PP)/聚酰胺6(PA6)/PP-g-MAH原位微纤复合材料。研究了复合材料的微观相形态以及结晶、流变和力学性能。结果表明,加入0.5%(质量分数,下同)的PP-g-MAH有利于大长径比PA6微纤的形成;而当PP-g-MAH的含量继续增加时,相界面相容性的提高反而阻碍了微纤的生成;加入0.5%PP-g-MAH的PP/PA6原位微纤复合材料在动态流变特性中呈现出很强的弹性响应,并且其结晶和力学性能显著改善。
Polypropylene(PP)/Polyamide 6(PA6)microfibrillar composites were prepared by melt extrusion-hot stretch-ing with maleic anhydride-grafted PP(PP-g-MAH)as a compatibilizer,and their phase morphology and crystallization,rheological and tensile properties were investigated.The results indicated that the addition of 0.5%PP-g-MAH(mass fraction)was beneficial to the formation of PA6 microfibrils with a high aspect ratio.A further increase in the content of PP-g-MAH improved the interfacial compatibility but hindered the formation of the microfibrils.The PP/PA6 microfi-brillar composites containing 0.5%PP-g-MAH presented a strong elastic response in terms of the dynamic rheological properties,leading to an obvious improvement in the crystallization and tensile properties of microfibrillar composites.
