文摘
- •
Polyethersulfone blended with polysulfide-amide (PSA) UF membranes were prepared.
- •
Hydrophilic PSA copolymer has nitro group, thiazole ring, and thioether linkage.
- •
The results were compared with polyvinyl pyrrolidone (PVP)/PES membrane.
- •
By increasing PSA amount, permeability and antifouling properties were increased.
- •
Membrane with 1 wt% PVP and 1 wt% PSA showed good flux and antifouling properties.
