以正硅酸乙酯和氟代烷基硅氧烷为硅源,十六烷基三甲基氯化铵为表面活性剂,三乙醇胺为催化剂在弱碱性条件下制备了氟烷基官能化的纳米介孔氧化硅颗粒。并采用动态光散射、FT-IR、SEM、TEM、氮气吸附-脱附以及UV-Vis光谱对产物进行了表征。结果表明:反应在45min后能得到粒径不再变化的30nm左右尺寸均一、高分散、高孔率的氟烷基官能化介孔氧化硅纳米颗粒。纳米颗粒涂层对光学玻璃具有良好的增透性能,是一种性能优良的光学涂层材料。
With tetraethyl orthosilicate and fluoroalkylsiloxane as silicon source, cetyltrimethylammonium chloride as surfactant and triethanolamine as catalyst, fluoroalkyl-functionalized Of nano mesoporous silica particles. The product was characterized by dynamic light scattering, FT-IR, SEM, TEM, nitrogen adsorption-desorption and UV-Vis spectroscopy. The results showed that after 45min reaction, the fluoroalkyl-functionalized mesoporous silica nanoparticles with uniform size, high dispersion and high porosity about 30nm could be obtained after 45min reaction. Nanoparticle coating on the optical glass has a good penetration performance, is a good optical coating material.
