摘　　要：利用静电纺丝法制备的聚丙烯腈/凹凸棒石纳米纤维膜吸附LiCl溶液后应用于溶液除湿。使用扫描电镜表征聚丙烯腈/凹凸棒石纳米纤维膜表面形貌,使用红外光谱仪分析其表面官能团。探究凹凸棒石质量浓度、纤维膜面密度、LiCl溶液浸渍时间对吸附LiCl溶液的聚丙烯腈/凹凸棒石纳米纤维膜的吸湿率的影响。吸附LiCl溶液的聚丙烯腈/凹凸棒石纳米纤维膜的吸湿率可达132.5%,除湿率可达83.2%。试验结果表明聚丙烯腈/凹凸棒石纳米纤维膜有望用作溶液除湿填料。Polyacrylonitrile/attapulgite nanofiber membrane prepared by electrospinning was used for liquid dehumidification after adsorbing LiCl solution.The surface morphology of polyacrylonitrile/attapulgite nanofiber membrane was characterized by scanning electron microscope,and the functional groups of it were analyzed by infrared spectrometer.The effects of attapulgite mass concentration,surface density and LiCl solution soaking time on the moisture absorption of polyacrylonitrile/attapulgite nanofiber membrane were investigated.The moisture absorption rate and liquid dehumidification efficiency of polyacrylonitrile/attapulgite nanofiber membrane with LiCl solution could reach 132.5%and 83.2%respectively.The experimental results showed that polyacrylonitrile/attapulgite nanofiber membrane was expected to be used as liquid dehumidification filler.
