- •
UF membranes were modified with polydopamine at various deposition conditions.
- •
Polydopamine modification decreased membrane molecular weight cutoff.
- •
Membrane pore size distribution was modeled using hindered solute transport model.
- •
Tradeoff between membrane selectivity and hydraulic permeability was observed.
