Abstract

Novel electrospun polyacrylonitrile (PAN) nanofibrous membranes were prepared by using heat-press lamination under various conditions. The air permeability and the burst-pressure tests were run to select the membranes for point-of-use air and water cleaning. Membrane characterization was performed by using scanning electron microscopy, contact angle, and average pore size measurements. Selected membranes were used for both air dust filtration and cross-flow water filtration tests. Air dust filter results indicated that electrospun PAN nanofibrous membranes showed very high air-dust filtration efficiency of more than 99.99 % in between PM and PM, whereas cross-flow filtration test showed very high water permeability over 600 L/(mhbar) after 6 h of operation. Combining their excellent efficiency and water permeability, these membranes offer an ideal solution to filter both air and water pollutants.

摘要

通过在各种条件下采用热压层压法制备了新型静电纺聚丙烯腈（PAN）纳米纤维膜。进行了透气率和爆破压力测试，以选择用于现场空气和水净化的膜。通过扫描电子显微镜、接触角和平均孔径测量对膜进行表征。所选的膜用于空气灰尘过滤和错流过滤水测试。空气灰尘过滤结果表明，静电纺PAN纳米纤维膜在PM与PM之间显示出超过99.99%的极高空气灰尘过滤效率，而错流过滤测试表明，运行6小时后水渗透率超过600 L/(mhbar)。结合其优异的效率和水渗透率，这些膜为过滤空气和水污染物提供了理想的解决方案。
