The Novel Organic-Inorganic Hybrid Materials Composed of Phenolic Resin and Silica

Organic-inorganic hybrid materials composed of phenolic resin and silica were prepared by in-situ polymerization of silicon alkoxides in phenolic resin matrix. The hybrid materials showed uniform morphology with very fine dispersion of silica. The transparency of the hybrid, the size of incorporated silica particles and its interface with matrix resin could be controlled. The uniform hybrid materials showed excellent improvements in mechanical properties.
