- •
A novel NF membrane has been prepared by LBL-assembly of core–shell star block copolymers.
- •
The multilayer-stacks of globular star polymers showed high water flux w/efficient dye removal.
- •
The hydrophobic cores of the star polymers offer good film durability in water.
- •
The hydrophilic arms at the membrane surface help mitigate membrane fouling.
