Resumo/Summary:

The present technology falls within the field of producing functional coatings for controlled release of volatile agents. More specifically, it consists in capsules, in particular microcapsules or nanocapsules functionalized with nano photocatalytic materials either in the inner or outer surface of the capsule, which by solar action or artificial light with the same electromagnetic radiation spectrum, releases the diffuser agent, which is a vapor, liquid or solid.
