摘　　要：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。Fluoroalkyl functionalized mesoporous silica nanoparticles were prepared under weak basic conditions u- sing tetraethyl orthosilicate and fluorosilane as silica sources, hexadecyltrimethylammonium chloride as surfactant and tri- ethanolamine as catalyst. The as prepared product characterization was carried out by dynamic light scattering, FF-IR, SEM, TEM, nitrogen adsorption-desorption and UV-Vis spectrum. The results showed that after 45 min reaction, the nanoparticles were formed and there were nearly no change in particle size distribution. The fluoroalkyl functionalized me- soporous silica nanoparticles with a diameter of approximately 30nm was uniform, high dispersed and porosity. As a coat- ing material with excellent optical properties, the nanoparticle coating acts as an efficient antireflective coating for optical glass substrates.
