摘　　要：采用差示扫描量热仪(DSC)研究了熔融插层法制备的尼龙6/乙烯-辛烯共聚物/有机改性蒙脱土(PA6/POE/OMMT)纳米复合材料的结晶行为,用Jeziorny法和Mo法分析了复合材料的非等温结晶动力学,并计算得到了相关的结晶动力学参数。结果表明,纳米粘土对基体有异相成核作用,但随着其在复合材料中含量增加,半结晶时间t1/2延长。最后,根据Huffman-Lauritzen理论计算了复合材料的非等温结晶活化能(Eα)。The crystallization behavior of polyamide 6/ ethylene-octene copolymer / organo-modified montmorillonite（PA6/POE/OMMT） nanocomposites prepared by melting intercalation was investigated using differential scanning calorimeter（DSC）,and the crystallization kinetics under non-isothermal conditions was analyzed using Jeziorny method and Mo method,and non-isothermal crystallization kinetics parameters were obtained.It is found that nano-clay works as a heterogeneous nucleation agent.However,the increasing OMMT loading level results in a higher semi-crystallization time.The activation energy of non-isothermal crystallization was calculated from Huffman-Lauritzen theory.
