Abstract

En 中文

• HFPS enables TA/PVP surface segregation via slowed kinetics and physical confinement. • Uniform TA/PVP layer serves as platform for high-density homogeneous AgNPs grafting. • HFPS membrane achieves 895 LMH/bar flux and >98% BSA rejection, outperforming NIPS. • Superior antibiofouling performance: 84.7% flux recovery and 3.7% flux decline. • Patterned HFPS segregation membrane is readily fabricated via hydrogel templates.
