以聚苯乙烯乳胶球、一种新型嵌段共聚物和一种离子液体表面活性剂为模板剂，制备了具有三峰结构的多孔二氧化硅。所得材料在三个长度尺度（小中孔：2 - 3 nm;大中孔：11 - 12 nm;大孔：360 nm）下表现出分级顺序。
Porous silica exhibiting a hierarchically ordered trimodal pore system with a well-defined reverse opal microstructure and bimodal mesoporosity in the walls has been prepared by using polystyrene latex spheres, a novel block copolymer and an ionic liquid surfactant as templates. The resulting materials exhibit hierarchical order at three length scales (small mesopores: 2−3 nm; large mesopores: 11−12 nm; macropores: 360 nm).
