Abstract

The electrical discharges at atmospheric pressure, such as corona, dielectric barrier discharge (DBD) and cold plasma jet have being used in many technological applications including the production of ozone, ultraviolet light generation, production of plasma panels, fluorescent lamps, air pollution control and more recently for the deposition of thin films and surface modification and sterilization of various materials. Their most important feature is the possibility to generate large volume of non-thermal plasma at high pressure without vacuum chamber. Among atmospheric plasma discharges, the cold atmospheric plasma jets have drown significant attention in recent years. The present research project proposes to continue the study and characterization of a plasma jet that is already in operation at the Plasma Applications Laboratory, Department of Physics and Chemistry of the FEG-UNESP. The research emphasis will be given on the applications of plasma jet in material processing and sterilization. A novel plasma jet application that is suggested in this project is the treatment of conductive materials like metals, semiconductors and carbonaceous materials in order to clean and activate their surface and as a result improve the material surface properties, such as wettability, adhesion and roughness. These characteristics are very important for various technological applications such as thin films growth on substrates with poor adhesion properties.
