| 摘 要： | 通过双螺杆挤出机制备出聚酰胺(PA)66/可反应性纳米SiO2(RNS)复合材料,采用Jeziorny法和Mo法对其非等温结晶行为进行了研究。结果表明,RNS具有较强的异相成核能力,能提高PA66的结晶速率,并使PA66的晶体结构和生长机制发生改变;通过对比PA66及其复合材料的结晶活化能发现RNS能够降低PA66的结晶活化能。

| Abstract: | PA66/reactable nano-SiO2 composites were prepared in a twin-screws extruder by melt compounding.The non-isothermal crystallization of the composites and neat PA66 was studied through Jeziorny and Mo methods based on DSC analysis.It showed that reactable nano-SiO2 had a strong heterogeneous nucleation effect on PA66 matrix.Its addition increased the crystallization rate of PA66,and led to changes in crystal structure,growth mechanism,and activation energy of PA66. |
