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 selfcleaning products based on TiO2 for 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.
