A new membrane synthesized onto a commercial tubular support was prepared by the directed synthesis of ordered mesoporous MSU-type silica through an interfacial reaction between a silica condensation catalyst (NaF) and new hybrid micellar building units made of silica precursors and nonionic surfactants. This membrane exhibits a specific permeation behavior toward PEO polymers that can be explained by the porosity morphology and silica charge pH dependence.
