SUSTAINED RELEASE SYSTEM FOR BIOCIDAL METAL COMPLEXES

摘要

The invention is directed to a sustained release system, to a method for preparing a sustained release system, and to a material for construction comprising said sustained release system. The sustained release system comprises a microp article, said microparticle comprising an intercalation material and an amount of one or more metal chelate complexes intercalated in said intercalation material of more than 10 wt.%, based on the total weight of the intercalation material and the one or more metal chelate complexes together, wherein said one or more metal chelate complexes have one or more free coordination sites, wherein said intercalation material comprises an inorganic layered material, wherein the inorganic layered material is modified with one or more ionic organic modifier compounds.
