摘　　要：Silane coupling agent was used to introduce polymerizable groups onto the surface of nano-SiO 2 particles. Then in-situ polymerization was carried out between the functionalized particles and methacrylic acid monmer to accomplish the surface modification of nano-SiO 2. Analysis of FTIR?TEM and TGA results show that methacrylic acid is grafted onto the surface of functionalized particles and the modified particles were stable. Contact angle measurement demonstrated that the modified particles were wetted by toluene completely and the contact angle with water was 105 ℃, indicating that the hydrophilic surface has been transfered to hydrophobic via the modification.
