1. A method for producing a polymeric carrier layer with a hydrophilic polymeric nanocoating, comprising:
producing the hydrophilic polymer nanocoating with a plasma polymerization process by applying organic precursor monomers onto the polymeric carrier layer to produce the polymeric carrier layer comprising filaments of at least one polymeric material,
wherein
the plasma polymerization process is performed in a plasma chamber having a plurality of rollers and/or expanders in a roll to roll system, a first electrode set and a second electrode set within the plasma chamber, and
the polymeric carrier layer is placed between first and second electrodes such that treatment on both sides of the polymeric carrier layer is performed.
