摘要： 利用非水溶剂快速挥发的方法,以三嵌段共聚物P123等作为结构导向剂,双三乙氧硅基乙烷作为硅源,合成出一系列大孔径(>4nm)、高有序度、具有二维六角结构并且墙壁中含双亚甲基的介孔有机氧化硅(PMO)材料,并通过XRD、TEM、N2吸附-脱附、29SiNMR和SEM等方法对材料进行了表征.

关键词: 介孔有机氧化硅材料, 合成, 非水溶剂快速挥发

Abstract: Highly ordered hexagonal mesoporous organosilicas with large pore size(>4 nm) were synthesized by non-aqueous solvent evaporation method using triblock copolymers as the structure-directing agents and 1,2-bis(triethoxysilyl)ethane as the organically bridged silica source. The mesoprous organosilicas were characterized by small-angle powder X ray diffraction(XRD), transmission electron microscopy(TEM), nitrogen adsorption, 29 Si MAS NMR spectroscopy and scanning electron microscope(SEM).

Key words: Mesoporous organosilica material, Synthesis, Non-aqueous solvent evaporation
