Method for producing antifouling coating of thin layer composite membrane for reverse osmosis and nanofiltration, such thin layer composite membrane and use thereof

摘要

The present invention provides a very thin, selective separation layer (preferably an aromatic) for thin layer composite membranes (collectively referred to as water filtration membranes) for reverse osmosis (hyperfiltration) and nanofiltration. A composite method for gently functionalizing the surface of molecules (including aromatic polyamides, polyurethanes, and / or polyureas) with a passive antifouling effect without impairing the selectivity of the water-selective separation layer made of polyamide and the water permeability of the membrane Is to achieve.
