“…The DCSBD electrode system consists of many parallel silver electrodes embedded in Al 2 O 3 ceramics (Fig. 1) [13,14]. Plasma surface treatment of PA-12 foil was realized on one side in a static regime (the sample was slightly being pushed two or three times in order to secure homogeneity of plasma treatment) with an input power of 400 W (2.56 W cm -2 ), ambient air was used as a working gas at room temperature, and with different treatment times 5, 10, and 15 seconds.…”

Abstract:The surface of a polyamide-12 (PA-12) foil was modified in order to improve the adhesive properties by two types of atmospheric pressure plasma sources. The samples were characterized using contact angle measurement, adhesive properties measurement and X-ray photoelectron spectroscopy (XPS). The ageing of the plasma modification was also studied. A significant increase in wettability was observed at different treatment times. The same effect was also seen in the adhesive properties -the adhesion was increased almost 12 times for 10 s DCSBD treatment in comparison to untreated PA-12. XPS analysis confirmed chemical changes due to the plasma modification of the PA-12. It was concluded that both plasma sources improve the adhesive properties of PA-12, with DCSBD obtaining better results.

“…APGD or APTD [36][37][38][39]. Contrary to the previously mentioned DBD configurations the DCSBD is capable of generating a macroscopically uniform plasma layer with high power density and energetic efficiency when operated in air [40,41]. That enables a fast and homogeneous in-line plasma treatment of materials at high-speeds e.g.…”

Diffuse Coplanar Surface Barrier Discharge in Artificial Air: Statistical Behaviour of Microdischarges

et al. 2014

Diffuse Coplanar Surface Barrier Discharge (DCSBD) is a novel type of atmospheric-pressure plasma source developed for high-speed large-area surface plasma treatments. The statistical behavior of microdischarges of DCSBD generated in artificial air atmosphere was studied using time-correlated optical and electrical measurements. Changes in behavior of microdischarges are shown for various electrode gap widths and input voltage amplitudes. They are discussed in the light of correlation of the number of microdischarges and the number of unique microdischarges' paths per discharge event.The 'memory effect' was observed in the behavior of microdischarges and it manifests itself in a significant number of microdischarges reusing the path of microdischarges from previous half-period. Surprisingly this phenomenon was observed even for microdischarges of the same half-period of the discharge, where mechanisms other than charge deposition have to be involved. The phenomenon of discharge paths reuse is most pronounced for wide electrode gap width and/or increased input voltage amplitude.

“…The DCSBD was designed to be suitable for flat surfaces treatment in particular. The DCSBD electrode system was powered by AC high voltage source which has a frequency (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) kHz and approximately 20 kV peak-to-peak voltage. In the present study, the discharge power is 320 W and it was operated in the air in order obtain a quasi-homogeneous diffuse plasma surface.…”

“…In the present study, the discharge power is 320 W and it was operated in the air in order obtain a quasi-homogeneous diffuse plasma surface. The system is equipped with oil cooling system in order to keep the system at the lowest possible temperature and maintain the gas temperature around 370 K. The DCSBD plasma is described in detail [12]. The plasma treatment was performed in dynamic treatment mode and the distance between the treated polymer surface and DBD plate was 0.5 mm.…”
