第51卷第9期2023年9月CottonTextileTechnology静电纺CA/CPB纳米纤维膜的制备及过滤性能研究杨景王平崔江舟郭佳敏宋秀峰（山西新华防化装备研究院有限公司，山西太原，030008）摘要：为了研发抗菌以及可生物降解的空气过滤材料，以可生物降解的醋酸纤维（CA）为主体原料，溴化十六烷基吡啶（CPB）为改性剂，采用静电纺丝技术，制备了CA/CPB纳米纤维膜并对其结构性能进行表征和测试。结果表明：制备的CA/CPB纳米纤维膜在过滤速率为0.0157m/s时，纤维膜渗透系数为3.50×10-11m2，经验孔隙率为98.0%，阻力压降为1.70kPa；相比于商业石英纤维滤纸，CA/CPB纳米纤维膜对PM2.5的拦截量更高，过滤效果更稳定；在375nm波段下和800nm波段下CA/CPB纳米纤维膜对黑炭（BC）的平均过滤效率分别达到80%和60%以上；CPB的加入使得纳米纤维膜具有更高的力学性能和耐热性能，CA/CPB纳米纤维膜水接触角为124°，呈现疏水性，堆肥试验和抑菌性试验表明所制备的CA/CPB纳米纤维膜具有生物降解性和明显抑菌性。关键词：静电纺丝；纳米纤维；空气过滤；纤维改性；生物降解中图分类号：TS171文献标志码：A文章编号：1000-7415（2023）09-0007-06PreparationandfiltrationperformancestudyofelectrospinningCA/CPBnanofibermembraneYANGJingWANGPingCUIJiangzhouGUOJiaminSONGXiufeng（ShanxiXinhuaChemicalDefenseEquipmentResearchInstituteCo.，Ltd.，Taiyuan，030008，China）AbstractInordertodevelopantibacterialandbiodegradableairfiltrationmaterials，thebiodegradableacetatefiber（CA）wasusedasthemainrawmaterial.cetylpyridinebromide（CPB）wasaddedasthemodifier.ElectrospinningtechnologywasusedtoprepareCA/CPBnanofibermembrane，thestructureandpropertywereevaluatedandtested.Theresultsshowedthatpermeabilitycoefficientoffibermembranewas3.50×10-11m2，porositywas98.0%andresistancepressuredropwas1.70kPawhenfiltrationspeedofthepreparedCA/CPBnanofibermembranewas0.0157m/s.Comparedwithcommercialquartzfiberfiltrationpaper，theinterceptamountofPM2.5forCA/CPBnanofibermembranewashigherandthefiltrationeffectwasmorestable.Under375nmwavebandand800nmwaveband，theaveragefiltrationefficiencyofCA/CPBnanofibermembraneonblackcarbon（BC）wasreachedupto80%andabove60%respectively.AdditionofCPBmadenanofibermembranewithhighe...
