Abstract

nanomaterials are applied in the restoration and conservation of Cultural Heritage because of several analytical advantages could be obtained thanks to their excellent chemical-physical, mechanical and engineered features. A great deal of nano-scale objects, as: nanoparticles, nanogels, nanofoams, nanosponges, nanopolymers are very useful for the cleaning of the art-work surfaces, restoration and conservation of wall paintings, marble stones, plasters, metallic surfaces and glass mosaic tesserae. Also for the deacidification of the ancient damaged paper, containing iron gall inks, and the preservation of parchment and canvas new nano-scale objects are easily synthesized and applied on these art-work surfaces

Recently, Nanomaterials and Nanotechnologies are applied also to the restoration and conservation of Cultural Heritage and artwork surfaces. The reasons for this seem to be related to the excellent chemical-physical properties of nanostructured materials, as: the large surface nominal area, the possibility to modify the “surface chemistry” in order to obtain selective nano-platforms, high electrical conductivity, high mechanical and thermal stability, biocompatibility towards the “end-users” (as restorers and conservators) and eco-sustainability toward environment. In particular the case of study, reported in this work, concerns the new bio-mineral synthesis approach for the CaCO3 nanoparticle production and their subsequent characterization. The analytical application was performed on the damaged plaster surfaces of the “Palazzo Lancia”, located on Largo Argentina (Rome, Italy). Palazzo Lancia is a Roman Renaissance Palace (1400-1450) and it presents several deterioration problems especially on the plaster surfaces. The consolidation strategy has been performed by using the conventional methodologies, widely reported in literature and then the new treatments based on the CaCO3 nanoparticles (synthesized by the bio-mineral approach) has been also applied for comparison. The efficiency of the new treatments results highly significant and promising for the restoration of Cultural Heritage, representing a valid alternative to the traditional/conventional treatments.
