The effects of acid content of coagulation bath and PANI content of spin dope on the morphology and structure of as-spun fibers were studied by SEM. And the effect of the microstructure of as-spun fiber on the tensile property was also discussed.

• 采用扫描电子显微镜 ( SEM)研究了凝固浴中酸的含量以及纺丝浆液中 PANI的含量对初生纤维形态结构的影响 ,并探讨了初生纤维的微观结构对纤维的拉伸性能的影响
