Communication: Self-standing films of surfactant mesostructured materials have been prepared with vinyltrimethoxysilane (VTMOS) as a silica source. The transparent films, obtained by the co-condensation of VTMOS and tetramethoxysilane, can easily be converted to porous silica films by calcination. The authors reveal the porous structure of these materials by X-ray diffraction and transmission electron microscopy investigations. Application of the self-standing films and the porous materials is envisaged in the fields of catalyst supports, separation, and hosts for bulky organic species.
