Abstract
The present invention provides a method for the preparation of thin film composite (TFC) membranes, preferably solvent resistant TFC membranes, by interracial polymerization (IFP), more in particular solvent resistant TFC membranes wherein a thin PA-layer is deposited on a porous support membrane. Said method comprises the replacement of the aqueous and/or the organic solvent in the IFP method by an ionic liquid (IL) as solvent for the monomers which form said TFC membranes, to alter the top layer morphology, thickness and crosslinking degree.
