摘　　要：为制备抗菌性好、安全、成本低且不影响原材料性能的非织造材料,以N,N-二甲基甲酰胺(DMF)为溶剂,聚丙烯腈(PAN)为溶质,双癸基二甲基氯化铵(DDAC)为抗菌剂,热风非织造纤网/布为接收基材,通过静电纺丝技术制备微纳米抗菌非织造材料,并对该抗菌复合材料的结构和性能进行表征。结果表明:抗菌微纳米纤维与热风非织造材料的3种复合方式均在保有材料原有力学性能、透气性和导水性能的基础上,赋予了非织造材料优异的抗菌性能;其中,成膜复合方式所得抗菌非织造材料的抑菌率最高,对大肠埃希菌和金黄色葡萄球菌的抑菌率可达99.9%。In order to prepare the nonwoven materials with high antibacterial properties,safety,low-cost and without affecting the properties of raw materials,using N,N-dimethylformamide(DMF)as the solvent,polyacrylonitrile(PAN)as the solute,didecyl dimethyl ammonium chloride(DDAC)as an antibacterial agent,and hot-air nonwoven mesh/cloth as the receiving substrate,micro-nano antibacterial nonwoven materials are prepared by electrospinning technology,and the structure and performance of the antibacterial composite material are characterized.The results show that the three composite methods of antibacterial micro-nano fibers and hot-air nonwoven materials all have excellent antibacterial properties and the composited nonwoven materials could maintain the original mechanical properties,air permeability and water conductivity.Among them,the antibacterial rate of the composite material is the highest,and the antibacterial efficiency against Escherichia coli and Staphylococcus aureus is up to 99.9%.
