Abstract:
      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.
