“…In water, P123 forms liquid crystals for concentrations between 20 and 65 wt%. 34,35 The latter is composed of a cubic phase (I 1 ) and of a hexagonal one (H 1 ) for P123 contents from 22 to 37 wt% and from 40 to 65 wt%, respectively. In an acidic solution, these limits are not modied.…”

“…The hydrophobic thickness dB and the hydrophilic thickness dA can be deduced from the It has been reported that in the pure P123 H1 and I1 domains, the values of RH are around 4.8 and 4.5 nm, respectively [35,53]. Taking into account the different bonds, the length of the extended PPO block is 24.5 nm and comparing this value to the hydrophobic radius, it was concluded that the hydrophobic chains of the P123 hexagonal and cubic phases are completely self-folded.…”

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.
