Abstract
This study investigated the interaction between micro-glow corona and organic materials. Micro-glow corona is very small plasma, which is generated on the tip of a needle electrode at atmospheric pressure. In this study, a hollow electrode with an inner dimeter of 4 mm was used as a counter electrode to generate the micro-glow corona. In addition, a small plate electrode was set behind a dielectric material as a sample to keep the micro-glow corona by barrier discharge. AC voltage at 100 Hz was applied to the needle electrode. When the gap distance between the tip of the needle electrode and the dielectric material was changed from approximately 0.5 mm to 10 mm, the discharge current and discharge onset voltage of the micro-glow corona were measured and analyzed. In a small area of the dielectric material surface, denaturation was observed after discharge.
