ABSTRACT:
This disclosure describes a self-assembly templating of a cationic surfactant in the presence of a silica precursor that is free of an excessive variability of the assembled shapes and has a yield approaching one hundred percent. This disclosure describes a self-assembly process that includes cooling and keeping a resultant solution at cold temperatures during the synthesis.
