Abstract
Inorganic/organic gels are prepared by hydrolyzing silica-containing alkoxides. Organics are introduced either by functionalizing the silica chemical hybrids) or by dissolving organic polymer in the solvent (physical hybrids). When the organic is a linear polymer, such as poly(vinyl acetate) or poly(ethylene oxide), the interactions between the organic and inorganic components are largely through surface hydroxyl groups. These interactions are responsible for the degree of visible light transmission.
