APPLASMA specialized in plasma such as handheld plasma, industrial plasma, hydrophobic, atmospheric plasma, glow plasma, hydrophobic plasma, hydrophilic plasma. APPLASMA researchers have been developing a variety of atmospheric plasma machines. With this technology, we have developed large scale atmospheric glow plasma as well as super size handheld plasma. we have also developed basic cleaning and surface treatment techniques as well as various functional treatments like as ashing, etching, reduction, sterilization, hydrophobic, etc. Furthemore, we have accomplished Super-hydrophobic nano thin film coating, which is one of most difficult fields in plasma technology.
