Abstract:
1. A method for preparing a hybrid organic-inorganic monomeric material comprising the steps of: a) peptizing an inorganic particulate material, the inorganic particulate material selected from the oxides, sulfides, sulfates, phosphates, arsenides, and arsenates, of non-noble metals, and mixtures thereof, in an inorganic acid to provide a solution of the inorganic particulate material; b) fractionating the solution obtained in step a) to provide a solution of inorganic particles having a particle size range of 5 nm to 100 nm; c) mixing the fractionated solution obtained in step b) with water miscible, organic solvent S1; d) reacting the mixture of step c) with a solution in an organic solvent S2 of a reactive silane-functional organic monomer.
