Plasma and nano for new age soft conservation

The EU PANNA project is dedicated to exploring the possibilities of using plasma for cleaning and protecting surfaces with special, fully removable coatings. The goals of the project are to design a portable atmospheric plasma torch, to develop a hydrophobic protective coating that can be applied with plasma, and to develop a tag or marker that is invisible in visual light and could be used for cataloguing art objects as well as aiding identification in the case of theft.

The developed technology and the new protective coatings are being tested on samples in the laboratory. The use of plasma to remove old protective coatings and graffiti on stone (marble, limestone and sandstone) and layers of soot and grime on wall paintings, and to reduce various corrosion products of metal (silver, bronze, brass) is being evaluated with both commercial plasma devices and the prototype that has been specially developed as part of the project.

To mark the end of the EU project, the Rathgen-Forschungslabor and its European partners will host a workshop on 2nd and 3rd September 2014, and a final conference on 4th September 2014 at the Sammlung Scharf-Gerstenberg in Berlin.
