MICRO- OR NANOCAPSULES HAVING PHOTOCATALYTIC PROPERTIES FOR CONTROLLED RELEASE OF DIFFUSING AGENTS AND RESPECTIVE METHOD OF PRODUCTION

摘要

The present disclosure relates to the production of functional coatings for the controlled release of volatile agents. More specifically, the present disclosure relates to capsules, in particular microcapsules or nanocapsules, chemically functionalised with photocatalytic nanomaterials upon the internal or external surface of the wall of the capsule. The capsule, by solar action or artificial light, can have the same spectrum of electromagnetic radiation, and can release an active agent. The capsule can also transport the active agent, which has photocatalytic properties. The capsule has an external diameter of 0.1-500 μm and can be formed by a wall and a nucleus to lodge the active agent. The present disclosure further relates to a method of obtainment of the capsules.
