Abstract

Low pressure non-equilibrium plasma polymerization is an emerging route for the preparation of a variety of pinhole free, conformal thin films, deposited on different substrates, using a room temperature, clean, environmentally benign process. The aim of our research was to develop effective protective coatings fitting the specific requirements of heritage preservation to prevent, or at least slow down, further corrosion of preserved metallic objects. The coatings were deposited by plasma polymerization of pyrrole on Romanian old coins. The resulting plasma polymers deposited on metallic supports are characterized by FTIR spectrophotometry, AFM, optical microscopy and colour changes.
