Nanofiltration (NF) is an effective technology for removing trace organic contaminants (TrOCs), while the inherent trade-off effect between water permeance and solute rejections hinders its widespread application in treatment.

The achieved benefits include narrowing pore size, improving interpore connectivity, enhancing microporosity, reducing thickness, which collectively realized simultaneous improvement enhancement TrOCs rejection performance. resulting membranes were superior both commercial membranes, especially water-TrOCs selectivity. effects using new monomers on membrane physicochemical properties systematically studied, underlying mechanisms enhanced separation performance further revealed by simulating process through density functional theory calculation measuring trans-interface rate monomers. This study demonstrates promising NF synthesis strategy designing structure reaction achieving excellent low energy input
