Tretament of wooden artifacts with atmospheric pressure plasma jet

In this work a cold atmospheric pressure plasma jet (APPJ) for sterilization and conservation of wooden artifacts is used. APPJ is rich of cold reactive species responsible for treatment of surfaces without thermal damage. Treatment of surfaces with APPJ can be performed on site either in interiors or exteriors/in open space. This research includes the application of a plasma jet for surface treatment of various wooden artifacts in terms of removing impurities and sterilization of microorganisms and worms, removing of subsequent interventions on the painted layer and, if it works, at some extent, it will complement standard techniques of desensitization/disinfection based on using hazardous chemicals, vacuum or gamma rays or using of chemical solvents for removing subsequent interventions. The goal of this work is to prove that this method for sterilization, disinfection of wooden artifacts and removing of subsequent interventions will work and can be applied to restoration and conservation of wooden artifacts. In this work we will show preliminary results on application of APPJ on artificially prepared paintings on wood including removal and change of morphology of surfaces. To some extent, APPJ is capable to remove and change of morphology of lacquer for wood while removal of paint layers as part of additional interventions is still a big issue. Further application of APPJ on sterilization and disinfection of wooden artifacts will be done.
