Abstract
A method for producing a carrier layer with a hydrophilic polymeric nanocoating wherein a polymeric carrier layer is produced with filaments of polymer material(s). The hydrophilic polymer nanocoating is applied with a low pressure plasma polymerization process using organic precursor monomers deposited onto the polymeric carrier layer and/or composite membrane. Additionally, a carrier layer includes a polymeric hydrophilic nanocoating.
Claims12
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.
