We develop corrosion protective coatings for lead heritage objects. The development of novel nanoparticle-based materials and physiocochemical studies at the nanoscale create new approaches to conservation science. We study monocarboxylate based microemulsions, polymeric networks (gels) and nanoparticles as alternative coatings. The coating formation and its corrosion resistance is characterized by surface analyses techniques, including electrochemistry, and synchrotron spectroelectrochemical studies.
