چکیده	This study focuses on the development and characterization of PEBAX-based membranes modified with poly(diallyldimethylammonium chloride) (PDDA) to enhance CO₂ separation performance. Membranes were fabricated by blending PEBAX-1657 with 10 wt% and 20 wt% PDDA using the solution casting method. Gas permeability measurements indicated that incorporating 10 wt% PDDA increased CO₂ permeability compared to pristine PEBAX, with improved CO₂/N₂ selectivity due to enhanced free volume and facilitated transport through amine functionality. However, at 20 wt% PDDA, reduced permeability was observed, attributed to increased crystallinity and reduced gas diffusivity and solubility.
