The present invention provides a photocatalyst film that includes a support; an organic-inorganic composite layer containing, in a graft polymer layer including a graft polymer chain directly bonded to the surface of the support, a crosslinked structure formed by hydrolysis and condensation polymerization of an alkoxide of an element selected from Si, Ti, Zr or Al; and a photocatalytically active layer, in this order, and a method for producing the same.

A hybrid bioactive glass comprising a plurality of POSS-cages each having at least one flexible arm radiating from an Si atom of the POSS-cage, each POSS-cage being covalently linked to another POSS-cage through an Si—O—Si linkage between two flexible arms. A method of forming a hybrid bioactive glass comprising the steps of providing a plurality of POSS-cages, each having at least one reactive flexible arm radiating from an Si atom detailed by —X—Si[R₁,₂,R₃], wherein X is an arm extension located between the Si—O—Si linkage and an Si atom of the POSS-cage, wherein R₁, R₂ and R₃ are also the same or different, and at least one of the R₁, R₂ and R₃ is an alkoxide, and reacting the plurality of POSS-cages through a sol-gel method to form a covalently-linked network and incorporating Ca+2 ions therein, the sol-gel process comprising hydrolysis and polycondensation reactions of the plurality of POSS-cages.

An alkali metal alkoxide or alkaline earth metal alkoxide in granular form.
