Beschreibung
Zusammenfassung:The present invention refers to a homogeneous nanostructured thin film manufacture method provided with self cleaning properties against organic substances to be applied directly on transparent materials surfaces used on optical components, especially in glasses or, on thin films with anti-reflex function previously deposited on this materials. More specifically, said method comprises a combination of hydrolytic and non-hydrolytic reactions. The self-cleaning action is activated by means of oxidation catalytic activity promoted in presence of titan dioxide (TiO 2 ) and exposition to electromagnetic radiation.
