Hydrophobic fluorinated polymer surfaces

13.12.2006

The invention at hand concerns novel hydrophobic fluorinated polymer surfaces, a method for their production and their use. comprised of homo- or copolymers, whereby the homo- or copolymers feature at least one fluoro-substituted aryl group. These novel fluoro-substituted aryl groups can be covalently bound to the primary polymer chain in every known way, eg via direct binding to the primary chain or via spacers. The production of the hydrophobic surfaces, based on the present invention, is carried out simply and reproducibly, for example, by electrospinning of a corresponding polymer solution.The hydrophobic polymer surface is available in the form of particles or as particles which are connected by fibers. Typical diameters are in the range of 3 µm to 1 nm, whereby the surfaces feature contact angles of greater than or equal to 160° and water-roll angles of 0°. In principle, all bases are suitable for use as a substrate to be coated with the novel hydrophobic polymers, in particular those made of plastic, metal or alloys.
