Dielectric barrier discharge (DBD) under atmospheric pressure is usually characterized with a large number of streamer discharge filaments. So its applications are greatly limited due to the non-uniform discharge mode. Nowadays, most research efforts are being focused on how to achieve the uniform DBD, and results show that there are many ways to improve the non-uniformity of the discharge, one of...
Like-glow plasma is frequently observed in ambient helium gas with dielectric barrier discharge (DBD). Actually, the high cost of helium makes it unsuitable for application. Therefore, a replaceable gas or mixture gases is necessary. As our reported work, like-glow plasma jet was obtained by adding a little ammonia (NH3) into argon. In this work, spatially-resolved spectra of argon atmospheric pressure...
To improve impregnating property of Polypropylene film, surface modification of Polypropylene film with dielectric barrier corona discharge in atmospheric pressure is carried out in this paper. A dielectric barrier corona discharge (DBCD) generator is designed and employed for surface modification. The Electrical properties of DBCD, surface analyses of Polypropylene films including chemical components,...
The electrical behavior of dielectric liquids such as transformer oil subjected to high electric-field and the possible breakdown phenomena is of great practical interest, since this liquid has been widely used in high-voltage power apparatus and pulse power systems, accordingly has led to extensive research work. This paper presents streamer discharge process such as initiation and propagation until...
Atmospheric pressure plasma jets (APPJ) in mono-gas have been investigated widely by different groups. Some works about the plasma jet in mixture gases ambient are also conducted in the field of polymer materials surface modification. However, the property and mechanism of APPJ in mixture gases ambient are not yet clear. In the work, the APPJs that were generated by using co-axis double ring electrodes...
