摘　　要：研究了改性纳米高岭土和马来酸酐接枝乙烯-辛烯共聚物(POE-g-MAH)对PA66/POE-g-MAH/改性纳米高岭土复合体系的力学和形态的影响。结果表明:改性纳米高岭土和POE-g-MAH具有协同增韧的效果,PA66/POE-g-MAH/改性纳米高岭土质量比为100/20/0.2时,复合材料的冲击强度比PA66提高了7.3倍;低温冲击强度比PA66提高了2.7倍;形态研究表明:改性纳米高岭土的加入对POE-g-MAH具有助分散的作用。The effects of nano-modified kaolin and maleic anhydride grafted ethylene-octene copolymer （POE-g-MAH） on the morphology and mechanical properties of PA66/POE-g-MAH/nano-modified kaolin were studied. The results shoed that nano-modified kaolin and POE-g-MAH had the coordination plasticizing effect, and the impact strength was about 7.3 times as high as that of PA66 when the mixture ratio of PA66/ POE-g-MAH/nano-modified kaolin was 100/20/0. 2. The impact strength of the composites at low temperature was enhanced 2. 7 times than PA66. The morphological research indicated that the addition of nano-modified kaolin had the effect of finely dispersed to POE-g-MAH in PA66.
