静电纺聚丙烯腈纳米纤维膜的制备及性能研究

Study on the fabrication and performance of electrospinning PAN nanofiber membrane

目前,采油废水随着石油开采难度的增加,治理难度也相应提高。采用静电纺丝技术,以聚偏氟乙烯(PVDF)、聚丙烯腈(PAN)为原料,N,N-二甲基酰胺(DMF)、N-甲基吡咯烷酮(NMP)为溶剂,制得了不同比例的PVDF/PAN纳米纤维膜。并对所做出来的PVDF/PAN纳米纤维膜的形貌和性质进行表征,优选出了最佳比例,在最佳质量比PVDF∶PAN=3∶2的基础上,优选出质量分数12%的PVDF/PAN纳米纤维膜进行实验。结果表明:此膜对采油废水的处理效果显著。

Currently,with the increasing difficulty of oil extraction,the processing difficulty of oil production wastewater has been increasing commensurately.The electrospinning was adopted to fabricate PVDF/PAN nanofiber membranes with different ratios,using PVDF and PAN as ingredients,DMF and NMP as solutions.The as-prepared membranes were characterized for their morphology and properties in order to determine the optimal ratio.The optimal ratio of PVDF∶PAN being 3∶2,the membrane with the optimal concentration of 12 wt%was selected,the performance was tremendous in processing oil production wastewater.
