Thin film composite (TFC) reverse osmosis (RO) membranes can be fabricated via interfacial polymerization using m-phenylenediamine (MPD) and trimesoyl chloride (TMC) as monomers on the surface of polysulfone membranes. The TFC RO membranes have shown excellent separation performance for water desalination process, while trade-off relationship between water permeability and salt rejection is a major problem to be overcome. Covalent organic frameworks (COFs) can be candidates for thin film nanocomposite (TFN) RO membranes as nanofillers because of their microporous structure. In this study, Schiff-base network-1 (SNW-1) was synthesized and incorporated into the selective layer of TFC RO membranes. As a result, water permeability of the membranes increases while maintaining salt rejection values. |
