摘　　要：以聚丙烯腈(PAN)为原料,通过静电纺丝制备PAN纳米纤维并沉积在聚丙烯(PP)针刺非织造材料的表面,制备成静电纺/针刺复合过滤材料。对复合过滤材料结构、纤维直径及过滤性能进行测试。结果表明:当PAN纺丝液质量分数为12%,纺丝电压15 kV,接收距离6.1 cm,溶液流速1 mL/h,接收时间1 h时,复合过滤材料的过滤效率可达到95.57%,而呼吸阻力仅为3.8 mm H_2O,可用于制备高效低阻空气过滤材料。Taking polyaerylonitrile （PAN） as raw material, the polyacrylonitrile （PAN） nanofibers are prepared by electrospinning, and then dopped onto the surface of polypropylene （ PP ） needle-punched nonwoven materials to prepare composite filter materials of electrospinning/needle-punched. The structure, average diameter and filtration efficiency of the samples are tested. The results indicate that the filtration efficiency of composite material can reach 95.57% with filtration resistance of only 3.8 mm H2O under conditions of PAN spinning solution concentration 12%, spinning voltage 15 kV, receiving distance 6.1 cm, solution flow rate 1 mL/h and reception time 1 h, which can be used as air filtration materials with high filtration efficiency and low respiratory resistance.
