Abstract
A coated, thin-film composite membrane includes a porous support and a polyamide barrier layer in contact with the porous support. A fouling-resistant and antimicrobial layer of star polymers is in contact with the polyamide barrier layer. The star polymers included hydrophilic arms of about 40 mol % to about 80 mol % of neutral hydrophilic moieties, and about 60 mol % to about 20 mol % of antimicrobial functional groups.
