High performance ultrafiltration composite membranes based on nanofibrous substrate with PDA coating and TAPS-NA immobilization

This is the authors' abstract. We don't add key points for this paper.

In this paper, we prepared a novel kind of high flux ultrafiltration (UF) membrane based on the phenolphthalein poly(ether sulfone)/polyvinylpolypyrrolidone (PVPP) composite membrane which the polydopamine (PDA) and N-[Tris(hydroxymethyl)methyl]-3-aminopropanesulfonic acid sodium salt were single side deposited on the PVPP layer. The results showed the coating layer endowed the composite membrane with superhydrophilicity and excellent bovine serum albumin resistance ability. The filtration of oil in water emulsion indicated the composite membranes displayed outstanding antifouling performance due to their hydrophilicity ability and surface nanoscale structures. Overall, this work offered a convenient approach to construct high performance UF membrane based on nanofibrous substrate.
