| Abstract: | Cyclohexyl silsesquioxane was synthesized by the hydrolytic condensation of cyclohexyl trichlorosi1ane in acetonitrile,and characterized by FT-IR and 29Si-NMR.The hydroxyl silsesquioxane was prepared by adding NMe4OH to the solution of cyclohexyl silsesquioxane in THF by controlling the suitable reaction condition,such as reaction time and the temperature.Epoxy resin was modified with hydroxyl silsesquioxane,and the thermal properties,dielectric properties and the hydrophobicity of the composites with different content of hydroxyl silsesquioxane were investigated with thermogravimetric analysis(TGA),dielectric constant and contact angle analysis.It was experimentally shown that the thermal stability,the dielectric properties and the the hydrophobicity of the composites were improved with the increase of the content of hydroxyl silsesquioxane. |
