摘　　要：固定增容剂马来酸酐接枝聚丙烯(PP-g-NA)的含量为10%,采用熔融共混制备出聚丙烯(PP)/PP-gMA/蒙脱土(MMT)纳米复合材料,并研究了不同含量MMT对复合材料的力学性能、球晶大小和SEM形貌等的影响。结果表明,当MMT质量分数为3%、PP-g-MA质量分数为10%时,PP/PP-g-MA/MMT纳米复合材料中MMT的分散性较好,冲击强度达到4.2 kJ/m^2,比纯PP提高了45%,而拉伸强度降低不明显。Polypropylene （PP）/polypropylene-graft-maleic anhydride （ PP-g-MA）/montmorillonite （MMT） nanocomposites were prepared by melt blending when the compatibilizer PP-g-MA content was fixed at 10%. The effects of MMT on the mechanical properties, the spherules size of PP and the SEM of composite were studied. It showed that when the mass percent of MMT was 3% and the weight content of PP-g-MA was 10% , the MMT nanoparticles were even dispersed in the PP matrix, and the impact strength of composites reached 4.2 kJ/m2, which was 45% higher than that of pure PP while the tensile strength did not significantly decrease.
