Electrode apparatus for dielectric barrier plasma treatment and method for surface plasma treatment

摘要

The invention relates to an electrode arrangement for a dielectric barrier discharge plasma treatment of an irregularly three-dimensionally shaped surface of an electrically conducting body used as a counter electrode, comprising a planar electrode (1) and a dielectric (2, 3), which is designed to be arranged at a defined distance from the surface to be treated in order to form a cold plasma, wherein said arrangement can be produced in a simple manner and can be reliably designed in the use thereof in that the dielectric (2, 3) is formed by a flexible planar material, which is provided with a structure (4) on the side of the flexible planar material facing the surface to be treated in order to form air guiding areas (7) when the dielectric (2, 3) lies on the surface to be treated, and in that the planar electrode is flexible and Is fastened to the dielectric (2, 3) in such a way that a layer (2) of the dielectric (2, 3) shields the electrode (1) from the surface to be treated.
