The Subject

: Polyamide (PA) thin film composite (TFC) membranes are widely used for large-scale water and wastewater treatment processes worldwide owing to their good balance between water permeability and dissolved solutes separation rate. The physicochemical properties of the cross-linked PA layer are the main criteria determining the filtration performance of the resultant TFC membrane and this selective layer can be created through interfacial polymerization (IP) between two immiscible active monomers, i.e., amine monomer in aqueous solution and acyl chloride monomer in organic solution. This review article intends to provide insights to researchers in fabricating improved properties of TFC membranes through utilization of secondary monomers during IP process. To the best of our knowledge, this is the first review that gives a state-of-the-art account of the subject matter by emphasizing the impacts of secondary monomers (both amine and acyl chloride monomers) on the properties of conventional TFC membranes for nanofiltration and reverse osmosis applications. Our review indicated that the introduction of secondary monomers into either aqueous or organic solution could alter the physical and chemical properties of PA layer which led to variations in membrane filtration performance. Nevertheless, more research is still required as most of the secondary monomers reported in the literature did not overcome the membrane trade-off effect between permeability and selectivity. The subject of improved PA layer development is a multi-disciplinary study that requires researchers with different backgrounds (e.g., materials science, chemistry, physics and engineering) to work together.
