摘要：
The present disclosure pertains to the field of the production of functional coatings for the controlled release of volatile agents. More specifically, it consists in capsules, in particular microcapsules or nanocapsules which are chemically functionalised with photocatalytic nanomaterials on the inner or outer surface of the capsule shell, and which release, by the action of sunlight or artificial light in the same spectrum of electromagnetic radiation, the diffusing or active agent, which can be a vapour, a liquid or a solid. The present disclosure thus relates to a capsule for carrying an active agent with photocatalytic properties, having an outer diameter of 0.1-500 µm, the capsule being formed by a shell and a core to contain the diffusing agent. The present disclosure also relates to a method for producing the disclosed capsules. The fields of use are the pharmaceutical, bioengineering, civil engineering, agrochemical, automobile and food industries.
