Abstract:
Nanofibrous mats, mainly fabricated by electrospinning technique, have gained substantial attention in the field of filtration-based membrane separation technology due to their unique morphology properties including small fiber diameter, high surface-to-volume ratio, high porosity, good mechanical properties, light weight, accessible functionalization, etc. As compared to the larger thickness, relatively lower porosity and disconnected microporous structures of polymer phase inversion membranes, the electrospun nanofibrous scaffolds exhibited high porosity and fully interconnected porous structures resulting in the remarkable improvement of permeability. In this paper, we summarize recent research progress in the field of membrane separation technology based on nanofibrous substrate filtration medium, and highlights the application of water purification and seawater desalination from nanofibrous microfiltration membrane and thin film nanofibrous composite (TFNC) filtration membrane. The future outlook of nanofibrous filtration membrane will also be discussed
