Reconstructed Polyamide Nanolayers via Two‐Stage Interfacial Polymerization Engineering for Precise Ion Sieving

open access: yesAdvanced Science, EarlyView.
A reconstructed polyamide nanofiltration membrane is engineered via a two‐stage interfacial polymerization strategy for lithium extraction from complex brines. Incorporated bidentate quaternary ammonium monomers enable synergistic steric and electrostatic effects within sub‐nanometer channels, achieving 60‐fold lithium enrichment and demonstrating ...
