Concentrated emulsions have been widely considered as templates for the preparation of macroporous structures. Replacing concentrated emulsions by fine ones should rather lead to materials having large mesopores. However, fine emulsions were barely investigated for this purpose. On the other hand, mesostructured silica SBA-15 can be prepared from Pluronic P123 micelles according to the cooperative templating mechanism. Starting from mixture of fine emulsion and Pluronic P123 micelles, it is expected to obtain silicas with a controlled hierarchical mesoporosity.

The fine emulsion has been formulated from the Kolliphor/Myristate/Water system. To get informations concerning the degree of compatibility between the two surfactants, which can affect the formation of the porous materials, the Kolliphor/P123/water system has been investigated in detail. The structural parameters of the mixed liquid crystal phases have been determined and the mixed micellar structure has been investigated by SAXS.

The hierarchical porous silicas have been synthetized combining fine emulsion and Pluronic micellar solution. The materials porosity features strongly depend on the weight proportion between the fine emulsion and the P123 micelles. If this proportion is lower than 5/5, mesoporous silicas present a dual mesoporosity. By contrast, by increasing this proportion the mesopore size distribution only shows large mesopores.

浓缩乳液已被广泛认为是制备大孔结构的模板。用细乳液代替浓缩乳液应该导致材料具有大的中孔。但是，为此目的几乎没有研究细乳液。另一方面，介孔结构的二氧化硅SBA-15可以根据协同模板机理由Pluronic P123胶束制备。从细乳液和Pluronic P123胶束的混合物开始，期望获得具有可控的分级介孔率的二氧化硅。

细乳液由Kolliphor /肉豆蔻酸酯/水系统配制而成。为了获得有关两种表面活性剂之间相容性程度（可能会影响多孔材料形成）的信息，已对Kolliphor / P123 /水系统进行了详细研究。确定了混合液晶相的结构参数，并通过SAXS研究了混合胶束结构。

已结合细乳液和Pluronic胶束溶液合成了分级多孔二氧化硅。材料的孔隙率特性很大程度上取决于细乳液和P123胶束之间的重量比例。如果该比例低于5/5，则介孔二氧化硅具有双重介孔性。相反，通过增加该比例，中孔尺寸分布仅显示大的中孔。
