MESOSTRUCTURED ORGANIC/INORGANIC HYBRID MATERIAL

摘要

An organic/inorganic hybrid material (OIHM) consisting of elementary spherical particles is described, each of said spherical particles consisting of a mesostructured matrix based on silicon oxide and of organic groups having reactive terminal functions linked covalently to the inorganic structure, said mesostructured matrix having a pore size between 1.5 and 30 nm and having amorphous walls with a thickness between 1 and 20 nm. Said elementary spherical particles have a maximum diameter of 10 µm. The silicon-oxide-based matrix may contain aluminium, titanium, zirconium and cerium. Two methods of preparing said material are also described.
