Abstract

This study addresses the permeability and fouling limitations of polyamide membranes through the development of thin-film nanocomposite (TFN) membranes incorporating an Ag2O/UiO-66 composite. Physicochemical characterizations confirmed the uniform dispersion and immobilization of the composite within the polyamide selective layer. Optimized synthesis significantly enhanced surface hydrophilicity, reducing the water contact angle from 81.7° to 42.2°. Consequently, the modified membrane exhibited an impressive water flux of 11.93 L.m-2.h-1 - 1.86 times higher than the pristine membrane, while maintaining a stable salt rejection above 92%. The formation of a hydration layer yielded an exceptional flux recovery rate (FRR) of 99.96% and reduced the fouling degree (DF) to a mere 6.80% (a 3-fold decrease). Furthermore, the incorporated Ag2O imparted near 100% antibacterial efficacy against both Staphylococcus aureus and Escherichia coli. These findings highlighted the Ag2O/UiO-66 system's potential for fabricating high-performance membranes with superior anti-fouling and antibacterial properties.
