We synthesized organically modified silicate (ORMOSILs) gels with colloidal silica (CS) (AEROSIL®) starting from polydimethylsiloxane (PDMS), tetraethoxysilane (TEOS) and calcium nitrate (Ca(NO3)2·4H2O) through sol-gel processing. Dynamic mechanical analysis indicated that relative height of the tanδ peak at about - 100 °C increased with an increase in the relative content of the inorganic components. This peak growth was accounted for by the relative increase in PDMS-colloidal silica particle interactions. The colloidal silica could control the mechanical behavior of the hybrids. The gel of a specific composition could deposit apatite within 3 days of soaking in the simulated body fluid (SBF), since it included many calcium ions on the surface.
