The work aims to study the effect on PEG in the inner layer as pore forming agent. The membrane comprised of dual layers, inner is PVDF/PEG while outer is PVDF/TiO2. PEG leached out from the membrane during phase inversion and thus created microvoid. The addition of PEG enhanced NP solution flux due to the macrovoid formation.
