Structure and formation of L3 phase surfactant templated inorganic oxides


The L3 (sponge) surfactant phase is a promising template for inorganic materials since it is composed of large, uniform water-filled pores separated by a surfactant bilayer. If the bilayer is coated in inorganic material, the pores of the resulting composite can be adjusted simply by water swelling of the initial L3 phase (rather than by increasing surfactant content) and no calcination is required to open up the major pore network. Previous work, using water soluble silica precursors, resulted in aerogel-like materials with poor reproducibility, due to a diffuse silica gel filling the water-regions rather than coating the surfactant bilayer. We are now preparing materials using the L3 phase but with hydrophobic inorganic precursors which are naturally segregated in the bilayer. We wish to use SANS and contrast variation to determine the detailed structures of our materials.
