Hierarchical mesoporous silicas containing two kinds of mesoporous size are successfully synthesized using the simple evaporation-induced self-assembly (EISA) strategy. Two blocks of hydrophobic segments (PE and PCL) in the poly(ethylene-block-ethylene oxide-block-ϵ-caprolactone) (PE-PEO-PCL) triblock copolymer are involved in the two types of mesopore after calcination, the PE segment being attributed to the face-centered cubic (fcc) morphology (spherical pores) and the PCL segment attributed to the tetragonal cylinder structure (cylindrical pores).
采用简单的蒸发诱导自组装（EISA）策略成功合成了含有两种中孔尺寸的层状介孔硅。在煅烧后，嵌段共聚物聚（乙烯-嵌段-聚环氧乙烷-嵌段-ε-己内酯）（PE-PEO-PCL）中的两段疏水性链段（PE 和 PCL）参与了两种类型的中孔形成，PE 段归因于面心立方（fcc）形态（球形孔），而 PCL 段归因于四方柱结构（圆柱形孔）。
