摘　　要：以聚丙烯腈(PAN)为原料,N-N二甲基甲酰胺(DMF)为有机溶剂,制备静电纺丝膜,通过改变纺丝电压、纺丝距离、纺丝液浓度和纺丝电解液浓度改变纤维直径,改变静电纺纳米纤维滤膜的层数,制备出具有梯度结构的静电纺过滤材料。将PAN纳米纤维收集在聚丙烯(PP)熔喷无纺布上制备成复合过滤膜。分析不同变量对于滤膜微观形态和宏观过滤性能的影响。结果表明,不同的变量对纳米纤维滤膜直径的影响程度不同,纤维直径大小对滤膜过滤性能影响较大。研究结论对制备高效低阻口罩滤芯材料具有参考价值。Using polyacrylonitrile(PAN)as raw material and NN dimethylformamide(DMF)as organic solvent,the electrospinning membrane is prepared by changing the spinning voltage,spinning distance,spinning solution concentration and spinning electrolyte.The concentration changes the fiber diameter and the number of layers of the electrospun nanofiber filter membrane to prepare an electrospun filter material with a gradient structure.Additionally,the PAN nanofibers are collected on a polypropylene(PP)meltblown non-woven fabric to prepare a composite filter membrane.Analyzing the effects of different variables on the microscopic morphology and macroscopic filtration performance of the filter membrane,the results show that different variables have different effects on the diameter of the nanofiber filter membrane,and the size of the fiber diameter has a greater impact on the filtration performance of the filter membrane.The research conclusion has reference value for the preparation of high-efficiency and low-resistance mask filter element materials.
