在阳极铝膜腔体内, 以三嵌段聚合物F127为表面活性剂合成出一维纳米介孔二氧化硅材料. 采用压力诱导合成方法能使纳米纤维沿着铝膜腔体有序生长排列, 并且只存在于铝膜的腔体内, 在铝膜表面没有残留. 在纳米纤维的两侧可以清楚地观察到具有六边形结构的孔道, 直径为12 nm. 考察了正硅酸乙酯的水解时间以及化合物的不同配比对材料形貌的影响.

One-dimensional nano-scaled mesoporous silica was synthesized within anodic alumina membrane pores surfactant by Pluronic F127. In contrast to soaking the AAM into the precursor solution way, we use pressure-induced infiltration approach and it has advantages that mesoporous silica hardly forms on the surface of AAM. Nano-fiber with highly uniform structure was arranged along anodic alumina cavity. The hexagonal pore structure is visible on both fiber edges with the diameters of the pores being about 12 nm. The effects of the ratio of chemical reagent and the reaction time on the mesostructure was also investigated. The resulting hybrid mesoporous membrane could be used for enzyme catalytic and nanofluidic systems.
