Abstract Efficient lithium/magnesium (Li + /Mg 2+ ) separation attainment is fundamental to the extraction of lithium from brine by nanofiltration membrane process, which essential for resource recovery and a circular water economy. However, poly(piperazine‐amide) nanofilm composite membranes, higher electronegativity affects Mg rejection consequently Li performance. Manipulating positive charge density pore size regulation membranes are determinative performance improvement. Here, new monomer 1,1′‐(hexane‐1,6‐diyl)bis(1‐methylpiperazin‐1‐ium) bromide containing bis‐quaternary ammonium cations employed as molecular building block fabricate polyamide nanofilms via interfacial polymerization. The dual quaternary ammoniums rod‐shaped conformation confer enhanced electropositivity, steric hindrance, loosely packed microporous network structure (pore diameter∼0.8–1.35 nm), high free volume. resultant exhibits permeance 28.34 L m −2 h −1 bar with good selectivity up 76.9. In addition, also chlorine stability owing lack sensitive −NH groups in formed tertiary amide structures. Computational insights on structural properties, formation, transmembrane ion transport behaviors provided. This study offers insightful theoretical technological concepts design construct materials energy‐efficient separations.
