Construction of a gelatin scaffold with water channels for preparing a high performance nanofiltration membrane

Abstract In order to achieve the aim of energy conservation and resource recovery in desalination and waste-water treatment, the nanofiltration (NF) membranes with a high permeability and selectivity should be developed urgently. Therefore, many researchers devoted to designing different hydrophilic polymer-interlayers for the thin-film composite (TFC) membranes, aiming to prepare NF membranes with outstanding separation performance. However, the effect of the thin polymer-interlayer (
