| 摘要 |
A method for the partial or total modification of functional groups on the surface of polymeric materials or polymer-containing materials, by means of combined plasma functionalization and localized thermal defunctionalization, is disclosed. At first, a surface of a polymer material is exposed to a cold plasma, whereby a desired polymer functionalization is achieved. After the plasma treatment, the surface is locally heated in an optional manner, primarily by means of an electron beam, resulting in local defunctionalization of the heated surface area. The directing of the electron beam across the surface of the material results in any desired distribution of functional groups on the surface. Also disclosed is a device for performing such a treatment. |
