Infrared gas phase study on plasma-polymer interactions in high-current diffuse dielectric barrier discharge A roll-to-roll high-current diffuse dielectric barrier discharge at atmospheric pressure was operated in air and Ar/N 2 /O 2 gas mixtures. The exhaust gas from the discharge was studied using a highresolution Fourier-transform infrared spectrometer in the range from 3000 to 750 cm À1 to unravel the plasma-polymer interactions. The absorption features of H x N y O z , CO x , and HCOOH (formic acid) were identified, and the relative densities were deduced by fitting the absorption bands of the detected molecules. Strong interactions between plasma and polymer (Polyethylene-2,6-naphthalate, or PEN) in precursor-free oxygen-containing gas mixtures were observed as evidenced by a high CO x production. The presence of HCOOH in the gas effluent, formed through plasmachemical synthesis of CO x , turns out to be a sensitive indicator for etching. By adding tetraethylorthosilicate precursor in the plasma, dramatic changes in the CO x production were measured, and two distinct deposition regimes were identified. At high precursor flows, a good agreement with the precursor combustion and the CO x production was observed, whereas at low precursor flows an etching-deposition regime transpires, and the CO x production is dominated by polymer etching.

“…This is consistent with for instance [1]. The ozone production is also on the high side for a corona plasma, especially compared with the theoretical maximum of around 1200 g · kWh −1 , [27], [28], but consistent with previous studies with the nanosecond pulse generator [23]. This shows that very short pulses are efficient for ozone production.…”

Abstract-Matching a pulse source to a plasma load is one of the main challenges to overcome to maximize the full potential of pulsed discharges for air purification applications. In this paper, we propose experiments that investigate the matching of a nanosecond pulse source to a corona plasma reactor that is aided by a high voltage on a tertiary electrode. The corona plasma reactor is a wire-cylinder reactor, as is commonly used in pulsed power plasmas. A tertiary electrode is situated on a dielectric layer against the cylinder of the reactor. On this tertiary electrode, we can apply a pulsed RF or dc voltage to provide an additional plasma and bias voltage in the corona plasma reactor. The pulse source that energizes the main corona plasma is the nanosecond pulse source of Kumamoto University, Japan. In this paper, we show the results of experiments with a dc voltage on the tertiary electrode. We varied the amplitude of the pulsed voltage as well as the dc voltage and investigated their effect on the corona plasma with energy and ozone measurements. The results show that the matching to the reactor increases with increasing dc voltages. However, the matching effect decreases with higher repetition rates. Furthermore, ozone measurements confirmed that a better matching also results in a higher ozone production, but in a lower ozone production energy yield.Index Terms-DC voltage, high voltage, nanosecond pulses, pulsed power supply.

“…In these applications, the main method for ozone generation is dielectric barrier discharge (DBD) (Alonso et al, 2001;Bai et al, 2001;Eliasson et al, 1987;Eliasson and Kogelschatz, 1991;Katsuji et al, 1996;Keto, 1981;Kitayama and Kuzumoto, 1999;Ohe et al, 1999;Sadadil et al, 1984;Velikonja et al, 2001). DBD is a typical non-equilibrium gas discharge and ozone is produced via energy consumption by dielectric barrier discharges in pure oxygen (Kogelschatz, 2003).…”

In this paper, combining hybrid discharge with pellet alumina catalyst is used for ozone generation. The hybrid discharge including corona discharge (CD), surface discharge (SD) and dielectric barrier discharge (DBD) may happen in the device. Factors that affect the ozone production efficiency and concentration are studied, such as energy density, power, gas flow rate, frequency, peak voltage and catalysts.
