Thin Film Composite Reverse Osmosis Membrane Containing Modified Multi- Walled Carbon Nanotubes for Desalination

Thin film composite reverse osmosis (TFC-RO) membranes incorporating NH۲-functionalized multiwalledcarbon nanotubes (NH۲-MWCNTs) were prepared by interfacial polymerization of metaphenylenediamine (MPD) and trimesoyl chloride (TMC). It was shown that with an increase in the carbon nanotubeloading, the membrane performance changed distinctly and led to a significantly improved salt rejectionand permeability flux. Meanwhile, the nanocomposite membranes showed better antifouling propertiesthan MWCNT-free RO membranes, suggesting that the incorporation of modified MWCNTs inmembranes is effective for improving the membrane performance.
