Abstract

Abstract:

The paper introduced the advantages of a combination of the membrane separation technology and electrospinning technology in the field of oil⁃water separation and reviewed the latest research progress in the hydrophobic electrospinning oil⁃water separation membranes， hydrophilic electrospinning oil⁃water separation membranes， and intelligent electrospinning oil⁃water separation membranes based on the classification of oil⁃water separation nanofiber membranes. A detailed introduction about the methods was provided for improving the oil⁃water separation performance of nanofiber membranes， including the modification by adding nanoparticles and preparation of multilayer nanofiber membranes. Finally， the future focus in the field of oil⁃water separation was proposed for the development of environmentally friendly nanofiber membranes with abilities for both oil⁃water separation and functions such as antibacterial properties and removal of heavy metal ion.
