Self-assembled structures for surfactant-inorganic component-water system confined in two flat walls

Lattice Monte Carlo simulations for the surfactant-inorganic component-water system are performed to study the morphologies formation of mesoporous materials in a flat confining space. The effects of component concentration, distance and hydrophilicity of two confining walls are considered in a systematic way and 12 different morphologies are observed. In addition to the well-known morphologies that have been found in the bulk before, such as the cylindrical, spherical and lamellar morphologies, new morphologies such as perpendicular lamellar morphology and bridge morphology are found in the flat confining space. Besides, the ternary phase diagram for the solution composition, the binary phase diagram for the surfactant concentration versus the distance of the two walls and that for different wall-surfactant interactions are given in this work.
