Highly crosslinked layer-by-layer polyelectrolyte FO membranes: Understanding effects of salt concentration and deposition time on FO performance

Dendrimeric Thin-Film Composite Membranes: Free Volume, Roughness, and Fouling Resistance

“…In a pioneer work Chen et al 44 combined DBES and PAS to measure free volume of TFC membranes as a function of depth. The method has been explored by only a few groups [45][46][47][48][49][50] and has been chosen as the most convenient in this work. observed for the membranes with 100 wt% PAMAM G0, followed by those with 50 wt% PAMAM G0.…”

Enhanced hollow fiber membrane performance via semi-dynamic layer-by-layer polyelectrolyte inner surface deposition for nanofiltration and forward osmosis applications

“…In Table 6, the FO performance of the id-LBL membrane using 0.5 M MgCl 2 draw solution with DI water as feed solution is compared with other polyelectrolyte LBL FO membranes [33,34] with glutaraldehyde [35] and UV crosslinking [36]. Despite the fewest modification steps involved, the id-LBL membrane is able to achieve the highest water flux with lowest reverse salt flux among all.…”

Layer-by-layer (LBL) assembly technology as promising strategy for tailoring pressure-driven desalination membranes

“…It has been reported that the LBL assembled structures can be easily destroyed under the severe conditions, such as high ionic strength and chlorine treatment which are always involved in water purification processes. [49,50] Therefore, it is of great importance to improve the stability of LBL assembled membranes, such as crosslinking by glutaraldehyde [51,52] and heating. [53] Particularly, crosslinking is the simplest and most widely used method to improve the stability of the polymeric membranes and glutaraldehyde is the most commonly used crosslinker.…”
