Thin-film composite membranes formed by conventional interfacial polymerization generally suffer from the depth heterogeneity of the polyamide layer, i.e., nonuniformly distributed free volume pores, leading to the inefficient permselectivity. Here, we demonstrate a facile and versatile approach to tune the nanoscale homogeneity of polyamide-based thin-film composite membranes via inorganic salt-mediated interfacial polymerization process. Mol. dynamics simulations and various characterization techniques elucidate in detail the underlying mol. mechanism by which the salt addition confines and regulates the diffusion of amine monomers to the water-oil interface and thus tunes the nanoscale homogeneity of the polyamide layer. The resulting thin-film composite membranes with thin, smooth, dense, and structurally homogeneous polyamide layers demonstrate a permeance increment of â?0-435% and/or solute rejection enhancement of â?0-170% as well as improved antifouling property for efficient reverse/forward osmosis and nanofiltration separations This work sheds light on the tunability of the polyamide layer homogeneity via salt-regulated interfacial polymerization process. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8SDS of cas: 7447-41-8).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.SDS of cas: 7447-41-8
