“…founder and owner) reported the first use of surface DBD to modify non-woven polymer fabrics [4,5], and since then surface DBD has been used to modify polymeric materials many times. However, long-term usage (>100 hours) of surface DBD leads to erosion of the upper strip-like electrode, which negatively affects the overall lifetime and renders its use in industrial applications problematic [6,7]. Limited lifetime and low level of safety (the surface of a plasma unit cannot be touched by a naked hand due to a direct contact with high-voltage electrode) resulted in efforts to develop plasma units based on coplanar design.…”

SummaryThe aim of the current paper is to introduce technology for the generation of high‐power density surface plasma by a diffuse coplanar surface barrier discharge (DCSBD) plasma unit. The diffuse and uniform plasma generated in low‐cost gases such as open air enables easy integration into novel or existing roll‐to‐roll (R2R) lines. We briefly discuss the history of the development of dielectric barrier discharges (DBDs) toward the most advanced plasma sources based on the coplanar arrangement of electrodes. Moreover, we present and discuss the advantages and disadvantages of the effect of volume and coplanar DBD treatments performed in R2R mode on the surface of polyamide. The paper also discusses the potential of R2R plasma treatments for next‐generation applications of novel flexible and printed electronics.

“…Studies of erosion processes in sDBD are relatively few, and are mostly connected with aerodynamic applications. The study of erosion of gold electrodes [12], comparison of ionic wind thrust generation [23] and discharge morphology [24] in copper and tungsten electrodes, and a phenomenological investigation of the degradation of aluminum electrodes of various thicknesses [25] are described in the literature. One should note that the existing works do not aim at the description of the fundamental processes of modification of the electrode edge, which are responsible for changing the discharge parameters, but rather focus on certain technological aspects.…”

“…It can be assumed that the formation of these pits is associated with the breakdown of the oxide layer on the aluminum surface [28]. It was shown in [25] that an oxide film with characteristic craters can be formed on tip cathodes in a negative corona. Presumably, the formation of the pit in the oxide occurs as a result of breakdown of the dielectric layer covering the edge.…”

Degradation in aluminium and copper foil electrodes in surface dielectric barrier discharges (sDBDs), operating in ambient air, is studied using various microscopic methods. It is determined that difference in the oxidation dynamics for these two materials lead to different morphology of the exposed electrode edge. The structure of the exposed electrode, in its turn, affects the dynamics of the microdischarges and the main integral electrical characteristics of the sDBD: power input, charge amplitude, shape of the charge−voltage cycle plot.

“…The erosion of the electrodes in surface dielectric barrier discharge (SDBD) has been studied in [27,28] with aluminum-foil electrodes which were subject to considerable modification under the influence of SDBDs. The erosion of the pin electrodes in the negative corona discharge was also reported in [29,30] describing the morphological changes that occur on aluminum electrodes.…”

Hybrid dielectric barrier discharges are investigated for plasma generated on the surface of a dielectric layer, where two conducting electrodes of high voltage and ground are formulated on the upper and bottom surfaces. Using a flexible thin polyimide-film of a thickness ranging from 25 to 125 μm, a plasma is generated with a voltage of about 1 kV and a frequency of 40 kHz. However, the surface of the dielectric layer was etched through a chemical reaction involving plasma oxygen radical species, and thus the polyimide films failed readily, resulting in dielectric breakdown within short operating time ranging from a few minutes to several tens of minutes, based on the film thicknesses of 25 μm and 125 μm, respectively. These plasma erosions were prevented by coating the polyimide surface with a 25 μm thick silicone paste. The siliconecoated film surface was then reinforced remarkably against plasma erosion as the organic polymer was vulnerable to chemical reaction of the plasma species, while the inorganic silicone exhibited a high chemical resistance against plasma erosion.
