Outline of Final Research Achievements

The purpose of this work is the academic foundation of plasma electrochemistry, which is regarded as the liquid-phase reaction induced by glow discharge electrolysis, and its application to material processes in liquid. For that purpose, we carried out (1) investigation of liquid-phase reaction in plasma electrochemistry, (2) magnetic nanoparticle generation, and (3) surface treatment of solid materials. It is clarified that the liquid-phase reaction is started from the very thin layer from the plasma-liquid interface by the electrons/ions/radicals irradiation of liquid surface from the glow discharge. For this application, Au/Ag composite nanoparticles and magnetite nanoparticles were synthesized and their synthesis processes were investigated. In addition, hydrophilization treatment of polypropylene as a target material was performed using plasma electrochemistry.
