摘要:: 通过原位聚合法制备PA66/SiO2纳米复合材料,利用SEM、TEM观察复合材料的微观结构,利用DSC分析复合材料的熔融和结晶行为,测试了其热性能和力学性能,探讨复合材料的结构与性能之间存在关系.结果表明:当SiO2纳米颗粒质量分数为0.8％时,可以均匀地分散在PA66基体中,SiO2纳米颗粒的加入提高了复合材料的结晶度,改善了其力学性能和热性能.

Abstract:: PA66/SiO2 nanocomposites were prepared by the in-situ polymerization method.The structure of SiO2 in polymer matrix was studied by TEM and SEM,and the melting and crystallization behaviors of composite materials were analyzed by DSC.Mechanical and heat properties were tested,too.The results indicated that SiO2 dispersed well in PA66 with nano-scale when the SiO2 was 0.8％,the mechanical properties and thermal stability of PA66/SiO2 nanocomposites were superior to neat PA66,meanwhile,the crystallinitywas improved.
