| 中文摘要: |
| 以聚己内酯(PCL)和聚丙烯腈(PAN)为溶质,N,N-二甲基甲酰胺(DMF)和三氯甲烷(TCM)为溶剂,然后加入磁性四氧化三铁纳米颗粒,利用静电纺丝技术纺织出具有磁性的复合纳米纤维膜,作为微生物生长的载体,应用于污水处理中。观察在SEM、X射线衍射、红外光谱测试、差示扫描量热法进行测试,力学性能通过动态力学来分析。研究发现,PAN的加入改变了纤维内部结晶的位置,而且所得到的纳米纤维直径分布较均匀,没有黏连现象；热疲劳方面有着较好的抗性,提高了重复利用的性能。 |
| 英文摘要: |
| Magnetic polycaprolactone（PCL）/polyacrylonitrile（PAN）composite nanofiber membranes were prepared by electrospinning using N，N-dimethylformamide（DMF） and trichloromethane（TCM） assolvents，and adding magnetic Fe3O4 nanoparticles.The obtained membranes were studied as microbial growth carriers for wastewater treatment.The result showed that addition of PAN changed the crystallization position of nanofiber，the diameter of composite nanofibers was small，and the diameter distribution was uniform.The composite nanofibers had almost no tackiness and didn’t adhere to each other.The mechanical properties of the composite nanofiber membranes were good.The effect of wastewater treatment was good when the membranes were used as the microbial growth carrier，and the membranes could be reused. |
