Hybridization of the organic and inorganic components was obtained by using the sol-gel method, then tripropylene glycol diacrylate as crosslinking agent and photoinitiator were added to formulate UV curable resin. In this study, concentration of organic component (2-HEMA)in sol-gel process used to investigate its effect on the curing behavior and the thermo-physical properties of cured film. DPC and FTIR were employed to monitor the UV curing reaction and find the radiating time for complete reaction. UV Curing kinetic was study by the DPC, and the thermo-physical properties, morphology were detect by DSC,TGA,SEM. Experimental results from this study indicate that, the curing behavior of UV resin was depended on the solvent concentration and the silicate content which make the gel effect early or delay. The size of silicate in the composite was around 50~60nm,so the composite exhibits excellent optical and physical properties. The excellent optic and physical properties of composite was resulted from the well dispersion of nano-size silicate in the hybrid.
