The constant exposure of the stone cultural heritage to the combined action of atmospheric agents and pollution represents a threat to its conservation and protection. Nano-sized titanium dioxide (TiO2) materials have been widely used as protective coatings due to their ability to create self-cleaning surfaces, thus limiting maintenance costs and promoting the degradation of pollutants. The present work aims to test innovative and self-cleaning products based on TiO2for applications in the field of cultural heritage. The properties of TiO2-based materials were evaluated by capillary water absorption, accelerated aging test in a climatic chamber, colorimetric and contact angle measurements.

Abstract
The constant exposure of the stone cultural heritage to the combined action of atmospheric agents and pollution represents a threat to its conservation and protection. Nano-sized titanium dioxide (TiO2) materials have been widely used as protective coatings due to their ability to create self-cleaning surfaces, thus limiting maintenance costs and promoting the degradation of pollutants. The present work aims to test innovative and self-cleaning products based on TiO2for applications in the field of cultural heritage. The properties of TiO2-based materials were evaluated by capillary water absorption, accelerated aging test in a climatic chamber, colorimetric and contact angle measurements.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
