摘要：

Mesoporous silica vesicles with controllable morphologies are successfully synthesized by the sol-gel method. The multi-lamellar structured products were obtained through assembly between a single-chain cationic surfactant of hexadecyltrimethyl ammonium bromide (CTAB) and silica precursors under the auxiliary of proper amount of diethyl ether. Snail-like, star-like and sharp-edged bowl-like morphologies were observed separately in the synthesized silica vesicles with the concentration of diethyl ether increased. The synthesis procedure provides a simple method to prepare vesicle-like materials. (C) 2003 Elsevier Inc. All rights reserved.
