Abstract
Sols for the synthesis of hybrid organic-inorganic materials have been prepared by mixing zirconiumn-propoxide and methacryloxypropyltrimethoxysilane (MPS). The synthesis was done in two steps: a 15 minute hydrolysis of a MPS:H2O:EtOH 1∶1∶2 mixture and then addition of 0.5 molar equivalent of zirconium alkoxide. All the experimental parameters—hydrolysis ratio, pH, dilution, pre-hydrolysis time—have been optimized through a detailed29Si and17O NMR analysis. Immediately after the addition, 94% of the initial water was consumed for the formation of Si−O−Zr bridges. Cleavage of these bonds, associated with formation of Si−O−SI, and Zr−O−Zr bridges are then observed during the aging time.
