<p>Subject of the invention is a method for partial or complete change of functional groups on the surface of polymer or polymer containing materials in combination with plasma functionalization and localised thermal defunctionalization. The surface of materials is first subjected to cold plasma, which provides the correct functionalisation of the polymer. Following the plasma treatment, the surface is locally heated by any method, preferably by a jet of electrons which results in a local defunctionalization at the hot spot. By conducting the jet of electrons across the surface of the material, any distribution of the functional groups across the surface of the material can be generated. Subject of the invention is also a device which facilitates the implementation of such processing.</p> |
