Multilayered polyelectrolyte complex based solvent resistant nanofiltration membranes prepared from weak polyacids

► Multilayered PEC membranes were prepared from PDDA and PAA by the LBL method. ► PEC membranes were prepared with different conditions. ► Morphology and SRNF performance of PEC membranes was studied in detail. ► Membranes showed more than 90% retention for RB from different solvents ► Results proving the good potential of these membranes in SRNF application.
