摘要
The invention relates to a combined method for gentle molecular surface functionalisation of the very thin, selectively-acting separating layer which preferably consists of aromatic polyamides, polyurethanes and/or polyureas, of thin-film composite membranes for reverse osmosis (hyperfiltration) and for nanofiltration, subsequently collectively termed water-filtration membranes, in order to achieve a passive antifouling effect without impairing the selectivity of the water-selective separating layer made of polyamides and the water-permeability of the membrane.
