结合溶胶-凝胶、静电纺丝和高温煅烧的技术与原理，制备了 TiO2纳米纤维，然后将研磨后的TiO2纳米纤维与PA6切片在双螺杆挤出机中进行共混、熔融纺丝制备出 PA6基复合长丝。利用 TEM、SEM表征了TiO2纳米纤维的结构形貌，通过视频显微镜观察了PA6基复合长丝的形貌，利用差式扫描量热仪(DSC)和流变仪对复合长丝的结晶性能及流变性能进行了测试分析，并且利用纤维强力测试仪对 PA6基复合长丝的力学性能进行了测试。结果表明，当TiO2纳米纤维含量较低时 PA6复合长丝的结晶度有所提高，剪切粘度变大，断裂强度有所提高。
The TiO2 nanofibers were prepared by combing sol-gel,electrospinning and high temperature calcina-tions techniques.Then the grinded TiO2 nanofibers and PA6 were blended and spun in a twin-screw extruder to prepare melt-spun PA6/TiO2 composite filaments.TEM and SEM were used to characterize the structural mor-phology of the TiO2 nanofibers.The video microscopy was applied to observe the morphology of the composite filaments.Differential scanning calorimetry (DSC),rheometer and fiber strength tester were adopted to analyze the crystallization,rheological and mechanical properties of the composite filaments.The results showed that the composite filaments with relatively low TiO2 amount presented higher degree of crystallinity,shear viscosi-ty,and breaking strength.
