Hybrid organic-inorganic nanocomposites composed of inorganic nanoparticles and organic polymers are synthesized and can be potentially used in the various fields. In the work, it was prepared from colloidal silica (CS) with vinyl trimethoxy silane (VTMS) by sol-gel process. The molar ratios of VTMS to CS were ranged from 1 to 10. During sol-gel process, hydrogens of hydroxyl groups on silica cluster were replaced by hydrolytically stable ≡Si-C2H3 through -O-SiC2H3 bonds on VTMS. After the sol-gel reaction was completed, the aqueous solvent was exchanged to ethoxyethanol (EC), followed by the incorporation into polymerizable oligomer, then finally it was cured by photopolymerization. The resultant nano-scaled dispersions were characterized by Fourier Transform Infrared (FT-IR)spectroscopy. The morphology of the resulting nanocomposites was examined by transmission electron microscopy (TEM) and viscosity test. |
