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.
A series of macropores (> 4nm) with high degree of order were synthesized by the method of rapid volatilization of non-aqueous solvent, triblock copolymer P123 as the structure-directing agent and bistriethoxysilylethane as the silicon source. The mesoporous organic silicon oxide (PMO) material with two-dimensional hexagonal structure and double methylene group in the wall was characterized by XRD, TEM, N2 adsorption-desorption, 29Si NMR and SEM.
