Autopulizia e superidrofilia

“The majority of industrial applications of photoactivated TiO2 lie in the production of self-cleaning surfaces, the uses of which range from antifogging rear-view mirrors, to self-cleaning windows, tiles and, more generally, building materials to textiles. This effect relies on the coexistence of two mechanisms: photocatalysis and superhydrophilicity, where the former degrades the functional groups such as carboxylic groups and fatty acids by which pollutants adhere to a surface, while the latter forces water to spread completely on the surface, carrying away particulate matter and degraded contaminants.”
