Laboratory for nanostructured materials for cultural heritage

Nanomaterials can be used for treating stone monuments or other cultural heritage materials.

Nano-additives can be suitable for:

  • Surface consolidation, occurring thanks to a material that penetrating by capillarity into the micro-structure of the decayed stone, is able to strengthen it by replacing lost original mineral bridges, and partially recovering lost mechanical properties.
  • Surface protection, occurring thanks to a material that penetrating by capillarity into the micro-structure of the stone, is able to prevent the ingress of liquid water, without any change in aesthetical, optical and chemical properties of the substrate.

The synthesis and the control of nanoparticles, as well as their chemical modification, allows to prepare versatile water based suspensions having a consolidating, anti-microbial or protective activity, very useful for cultural heritage materials.
