Oleophobic and / or permanent hydrophobic modification for polymer surfaces, processes for producing the modification and their application

摘要

The invention relates to an oleophobic and/or a permanent hydrophobic finish for polymeric surfaces in a thin film. The film is formed from at least one layer of a water-soluble polycation and/or a cationic synthetic resin. In order further to improve the oleophobic and/or permanent hydrophobic properties, the film may additionally contain a long-chain surfactant or an alkyl-substituted polyanion.
