在这项工作中，沸石咪唑骨架-8（ZIF-8）为基础的杂化纳米纤维膜成功地通过一个简单的策略，在聚合物基板上原位加载。此外，通过扫描电子显微镜和X射线衍射证实了杂化膜。这种混合结构的纳米纤维网应用于重金属处理相结合的微孔材料的独特性能作为活性尺寸的重金属吸附与高表面积的电纺聚丙烯腈（PAN）膜作为多孔基材。该结构具有180 L/（m2·h·psi）的高渗透通量，对水中重金属的去除能力比纯PAN膜提高了3倍以上。此外，重金属的去除能力保持在几个循环过程后，这是一个重要的特点，作为过滤膜的混合电纺膜。该杂化电纺膜适用于从水中去除重金属。
In this work, Zeoliticimidazolate framework-8 (ZIF-8)-based hybrid nanofibrous films were successfully fabricated by a simple strategy of in situ loading on a polymer substrate. In addition, the hybrid film was confirmed by scanning electron microscopy and X-ray diffraction. This hybrid-structure nanofibrous web was applied in heavy metal treatment by combining the unique properties of microporous material as active sizes for heavy metal adsorption with a high surface area of electrospun polyacrylonitrile (PAN) film as the porous substrate. This structure performed with a high permeation flux of 180 L/(m2·h·psi), and the capacity of heavy metal removal from water increased more than three times compared with pure electrospun PAN film. Moreover, the capacity of heavy metal removal was maintained after several recycling processes, which is a significant characteristic of the hybrid electrospun film as a filtering membrane. The hybrid electrospun film is suitable for heavy metal removal from water.
