摘要

micro or nanocapsules with photocatalytic properties for controlled release of diffusers and method of obtaining them. The present disclosure is in the field of manufacturing functional coatings for the controlled release of volatile agents. more specifically, it consists of capsules, in particular microcapsules or nanocapsules chemically functionalized with photocatalytic nano materials on the inner or outer surface of the capsule wall, which by solar action or artificial light with the same spectrum of electromagnetic radiation, release the diffuser / active agent which is a vapor, liquid or solid. The present disclosure thus relates to a capsule for carrying an active agent with photocatalytic properties, with an outer diameter between 0.1-500 µm, wherein the capsule is formed by a wall and a core for housing the diffuser. The present disclosure also relates to a method of obtaining the capsules now disclosed. Applications target pharmaceutical, biotechnology, civil, sanitary, agrochemical, automotive and food engineering.
