摘要: 将不同PAN浓度的纺丝液进行静电纺丝制备纳米纤维多孔膜。并对制备的静电纺PAN纳米纤维膜的形貌、纤维直径、孔隙率和比表面积、力学性能以及过滤性能进行表征和测试。结果表明,随纺丝液浓度的增加,纤维平均直径明显增加,对应静电纺多孔纤维膜在综合力学性能较高的基础上的过滤效率降低,其中,试样2的过滤效率最高,在过滤速度为5.3 cm/s,实验颗粒尺寸为0.06~0.43 μm时,其过滤效率在99.9%~99.993%之间,优于常用的高效过滤器,其最易渗透粒径大约为0.10 μm。

Abstract: PAN nanofibrous porous membranes from different solution concentrations were prepared by electrospinning, and then the morphology, diameter of fiber, porosity and specific surface area, mechnical properties and filtration efficency of the fiber membranea were tested and analysised. The results show that the average diameters of nanofibers increase as the concentrations of spinning solutions rise, the as-spun nanofibrous porous membranes which exhibit good overall mechnical properties show lower filtration efficiency, the sample 2 presents the best filtration efficiency among them. When the filtration rate is 5.3 cm / s and experimental particle size is 0.06 ~ 0.43 μm, its filtration efficiency is between 99.9% and 99.993%, better than the commonly used high filter. Moreover, its most penetrating particulate size is about 0.10μm.
