Abstract

The contribution of Science to the Conservation of Cultural Heritage radically grown up in the last years mainly thanks to the advancements in the knowledge of the physico-chemical composition and properties of the materials constituting the works of art, and to the development of several innovative methodologies for Conservation, based on soft- and hard-nanomaterials. Nanotechnology represents one of the most promising fields in conservation science, providing new materials and solutions to old conservation issues. Dispersions of humble alkaline nanoparticles of magnesium and calcium hydroxide in different solvents, microemulsions and nano-magnetic gels embedded with microemulsions have been used to restore frescoes, to remove polymers or clean mural and oil paintings, or to de-acidify paper, wood and canvas. These systems are characterized by scale lengths typical of nanoscience, i.e. below 100 nm in one or more dimensions, and constitute a new platform for conservation of cultural heritage. The dimensions in the nanoscale range and the high surface-volume ratio provide a high reactivity that plays a crucial role both for consolidation of limestones and for deacidification of cellulose. Moreover, the usage of hydroxide nanoparticles for wall paintings conservation respects the fundamental principle of physico-chemical compatibility between the restoration product and the substrate, granting a long-term stability to the treated works of art, whereas traditional treatments may show dangerous drawbacks. With illustrative examples on consolidation of wall paintings, and deacidification of books and wood, this contribution will report on some recent case-studies highlighting the improved performances of nanoparticles and nanocontainers (micelles, microemulsion, nanogels, etc.) respect to traditional conservation methodologies.
