Surface| Zusammenfassung: | The polysilsesquioxane xerogels have been synthesized using hydrolytic copolycondensation of 1,2-bis(triethoxysilyl)ethane and 3-aminopropyltriethoxysilane. Time of gel aging and ratio of reacting alkoxysilanes have been found to be major factors effecting on the formation of porous structure xerogels. A mesoporous xerogel is formed with specific surface area of 290 m2/g and pore volume of 0,78 cm3/g when aged for 30 days with the ratio of reacting components of 4:1 (NH4F being a catalyst). |
