Hierarchical meso-mesoporous and macro-mesoporous silica templated by mixtures of polyoxyethylene ­fluoroalkyl ether and triblock copolymer

We report here the synthesis of different kinds of hierarchical porous silica materials by using mixtures of an amphiphilic block copolymer (Pluronic P123) and a nonionic fluorinated surfactant. In particular, we have taken advantage of the difference in polarities between the two compounds to desig...
