| 摘 要： | 研究了在不同工艺条件下制备的聚丙烯腈(PAN)基中空碳纤维膜和预氧化膜及其结构特征。通过实验得出,基膜的拉伸使预氧化膜和碳化膜致密化,在制备PAN基膜时加入聚甲基丙烯酸甲酯(PMMA)和聚酰亚胺YJ-16添加剂,有助于保持中空纤维膜的指状孔结构,得到孔结构较好的预氧化中空纤维膜和中空碳纤维膜。

| Abstract: | The PAN-based hollow carbon fiber membranes and its pre-oxidized hollow fiber membranes prepared under different conditions as well as their morphology were investigated.It is found through experiments that drawing of the base membrane makes the pre-oxidized and carbon membranes compact,adding PMMA and polyimide(YJ-16) to the PAN based membrane can help to keep the finger-like pore structure of the hollow fiber membrane,thus obtaining pre-oxidized hollow PAN based membrane and hollow carbon fiber membrane with better morphology. |
