摘　　要：通过静电纺丝技术制备了不同厚度的聚丙烯腈(PAN)纳米纤维膜,并对其形态、透气透湿性能及拉伸力学性能进行了测试分析.研究发现,PAN纳米纤维成纤良好,纤维连续且分布均匀,直径分布约在80~600nm范围内;纳米纤维膜的透气性随着膜厚度的增加而降低,但透湿量和厚度之间并没有明显规律可寻,不同厚度膜的透湿性能良好,透湿量相差不大,约在5000~5300g/(m2·d)范围内;纳米纤维膜的断裂强度随着厚度的增加而呈现先增加后减小的趋势,厚度为50μm时,断裂强度达到最大值,为0.79 MPa.Polyacrylonitrile （PAN） nanofiber membrane with different thicknesses are prepared by electro- spinning, and the morphology and air permeability and moisture permeability and tensile mechanical prop- erties of nanofiber membrane are tested and analyzed. The results show that the PAN nanofibers have a good fiber-forming, continuity and distribution with the range of diameter distribution from 80 nm to 600 nm. The air permeability of the nanofiber membrane decreases with the increase of the thickness. There is no direct relationship between moisture permeability and thickness of nanofiber membrane, which possess excellent moisture permeability with the range of air permeable volume from 5000 g/（m2· d）to 5300 g/ （m2 ·d）, and the value indicates less differences among different thicknesse membrane. The tensile break- ing strength of nanofiber membrane increases first and then decreases with the increase of the thickness, and the maximum value is 0.79 MPa occurring at the thicknesses of 50μm.
