Electrode Array for a Dielectrically Impeded Plasma Treatment

An electrode arrangement for a dielectric barrier discharge plasma treatment of a surface of an electrically conductive body used as a counter-electrode, comprising:

• a flexible planar electrode;
• a dielectric which is composed of a planar flexible material and which, with a layer preventing a direct current flow, shields the electrode from the surface to be treated,
• wherein the dielectric, by way of a structure with projections, can rest on the surface to be treated,
• wherein air spaces for the formation of the plasma are formed between the projections,
• wherein the structure is formed as a lattice which has chambers forming the air spaces, and the chambers are closed off at the bottom by the layer of the dielectric preventing the direct current flow and have a side which is open to the surface to be treated,
• wherein the chambers are delimited by mutually adjoining walls, wherein each wall has a material thickness of between 0.1 and 1.0 mm and a height of 0.5 to 3 mm, and
• wherein a contact face for bearing on the surface to be treated consists of end edges of the at least some of the mutually adjoining walls of the lattice formed by the structure.
