High Performance Thin Film Nanofibrous Composite Membrane for Organic Solvent Nanofiltration

Book - Dissertation

Traditional polymeric membranes are confronted with several challenges including limited water flux and salt selectivity. Progresses in nanotechnology provide opportunities to design energy-efficient membranes for water desalination. Nano materials with special properties play a significant role in nanocomposite membrane performance for enhanced water flux and salt rejection. Well designed porous nanomaterials and layered nanosheets are essential to providing extra water channels and salt ion rejection barriers. This proposal proposes the preparation of 2-dimensional nanomaterial by liquid exfoliation in large-scale and their corresponding modified products. The nanocomposite polymer membrane will be fabricated via interfacial polymerization with the incorporation of the prepared nanomaterials. Fundamental understanding of the relationship between the membrane structure and the incorporated 2D nanomaterial will be investigated and its characteristic separation properties verified. With respect to industrial scale production of the nanocomposite membrane, experiments will be carried out to optimize the formula and process to achieve excellent filtration performance. Furthermore, the background, objectives and significance of the study are presented and finally, the methodology to be used is discussed.
