Abstract

Paper-based cultural heritage objects are subject to natural deterioration due to internal and external factors, that is, the presence of heavy metals, incorrect conservation, humidity, exposure of the artifacts to pollutants, light, and high temperatures. To contrast the decay of the original objects, it is necessary to study and apply innovative specific techniques, set up novel preservation methodologies, and implement or synthesize new products. As the nanomaterial science field developed over the last decades, the usage of nanomaterials in cultural heritage gained a prominent role. Such an excitement for the novel materials opened the path for an uncontrolled transfer of nanoparticles developed for different applications to paper restoration, neglecting all their possible interactions with the support or the graphic media. The aim of this work was to synthesize new nanomaterials expressly conceived for the treatment of library materials. To evaluate their possible insertion in the official conservation treatments that are subjected to validation by Istituto Centrale Restauro e Conservazione Patrimonio Archivistico e Librario, the new nanomaterials were tested both on laboratory paper samples and on original documents. This work presents the results of these studies (some of which still preliminary) stressing the positive and extremely promising outcomes of this research.
