Abstract

Plasma processing is key technology for electronics, bio-medicine, aerospace, automotive, textile or environmental engineering. It is widely used in conjunction with vacuum. Recent advances in gas discharge physics led to cold plasma sources, suitable for processing at atmospheric pressure. The major types of plasma sources are based on discharges with dielectric barriers or on discharges with bare electrodes-having the electrodes in contact with plasma. The idea of the project is to design and construct dedicated radiofrequency plasma jet sources based on the two discharge types, but able to work at similar parameter values (consumed power and gases), and afterwards to measure and compare their performances in terms of active species production, spatial extension and in processing - modification of polymers wettability and decomposition of chemicals in water. In the plasma processing field the process developing is mostly empirical, based on a “trial and error” procedure. Guiding the activity of process developing is very important: the proposed project will provide criteria for an “a priori” allocation of a specific type of plasma source to a given application (depending on the concrete request for a type of species, concentration, spatial extension, etc.), saving lot of time and money, thus having significant impact for technologies.
