Poly (ether imide) [PEI] ultrafiltration membranes are coated by polydopamine (PD) and immobilizedwith silver nanoparticles (AgNPs) to improve the permeation, contaminant separation and anti-foulingproperties. The tailored membranes displayed enhanced permeability (97.2 Lm 2 h 1), hydraulicresistance (13.8 kPa/Lm 2 h 1), average roughness (43 nm), contaminant rejection (>97%) with a higherflux recovery ratio (>95%). PEI/PD/Ag membranes showed anti-biofouling property against gramnegative and gram positive bacteria and facilitated the separation of toxic contaminants. The outstandingstability of PD coating and the presence of AgNPs offer effective and safe water separation.
