摘　　要：采用熔融插层法制备了HDPE/PA6/OMMT纳米复合材料,用XRD、TEM和SEM对复合材料进行了表征。测试表明,聚合物大分子链已经插层进入蒙脱土片层之间,形成了插层型纳米复合材料。当蒙脱土添加量为3phr时,蒙脱土以完全剥离的形态分散在分散相PA6中;当用量增加至7phr时,使得两相的结构发生了逆转,即多组分的HDPE成为分散相,而PA6成为连续相。当蒙脱土用量为3phr时复合材料表现出最佳的机械性能。HDPE/PA6/Organo-montmorillonite （OMMT） composites were prepared by means of melting intercalation, and the microstructure of the prepared composite was characterized by means of XRD, TEM and SEM. The results of tests showed the polymer macromolecular chains were interclated into OMMT layer, resulted in interclated nano-meter composite. When the addition of OMMT was 3 phr, OMMT dispersed in PA6 in a fully exfoliated phase; when the addition waS up to 7 phr, the microstructure of the two phases changed in reverse： HDPE became disperse phase, and PA6 continuous phase. The composite had the best mechanical properties when the content of OMMT was 3 phr.
