摘要：

The synthesis system for mesophase formation, using the diprotic anionic surfactant N-myristoyl-L-glutamic acid (C(14)GluA) as the structure-directing agent (SDA) and N-trimethoxylsilylpropyl-N,N,N-trimethyl-ammonium chloride (TMAPS) as the co-structure-directing agent (CSDA), has been investigated and a full-scaled synthesis-field diagram is presented. In this system we have obtained mesophases including three-dimensional (3D) micellar Cubic Fm (3) over barm, Pm (3) over barn, Fd (3) over barm, . micellar tetragonal P4(2)/mnm, two-dimensional (2D) hexagonal p6mm and bicontinuous cubic Pn (3) over barm, by varying the C(14)GluA/NaOH/ TMAPS composition ratios. From the diagram it can be concluded that the mesophase formation is affected to a high degree by the organic/inorganic-interface curvature and the mesocage-mesocage electrostatic interaction. Bi-continuous cubic and 2D-hexagonal phases were found in the low organic/ inorganic-interface curvature zones, whereas micellar Cubic and tetragonal mesophases were found in the high organic/inorganic-interface ice curvature zones. Formation of cubic Fm (3) over barm and tetragonal P4(2)/mnm was favoured in highly alkaline zones with strong mesocage-mesocage interactions, and formation of cubic Pm (3) over barn and Fd (3) over barm was favoured with moderate mesocage-mesocage interactions in the less alkaline zones of the diagram.
