Abstract:

Electrostatic interactions between cationic polyamine and anionic surfactant cause assembly to form composite micelles. The anionic surfactant/cationic polyamine composite micelles can then act as a template to co-assemble with silica precursors to form mesostructured silica. Mesoporous silicas with different mesostructures and morphologies were obtained by changing the synthesis temperature, the amounts of cationic polyelectrolyte or silica precursor and the species of anionic surfactant. This anionic surfactant/cationic polyamine composite micelle template method comprises a general method for synthesizing mesoporous silicas.

Key words: Cationic polyamine, Anionic surfactant, Biomimetic synthesis, Mesoporous silica
