Abstract］ Objective To Treating the nano-SiO2 particle by silicon coupling reagent, functionalize the SiO2 by making double bond on its surface. Polymerizing on the surface of nano-SiO2 surface by the method called emulsion polymerization, the nano-SiO2 is covered by polymer to get the PMMA-KH-570-nano-SiO2 complex material. Test the surface structure of the surface of nano-SiO2 by FTIR, and test sort of its mechanical performances.Comparing the treated nano-SiO2 which is directly dispended in the PMMA emulsion with the SiO2 without any treatment, we are trying to find an effective method which can not only increase the dispersion of SiO2, but also improve the mechanical performance of the artificial teeth.
