中文摘要：

报道了一种新的囊泡合成方法——荷电固体纳米颗粒诱导囊泡的自发形成．研究发现，将5．0g／L带结构正电荷的Mg3Al类水滑石（HTlc）溶胶和0．02mol／L由两性表面活性剂十二烷基甜菜碱（C12BE）和阴离子表面活性剂双（2-乙基己基）琥珀酸磺酸钠（AOT）组成的溶液（C12BE与AOT物质的量比为3：2）混合，当HTlc溶胶与表面活性剂溶液的体积比在1：9～4：6范围内，在HTlc纳米颗粒的诱导下可自发形成囊泡，并获得稳定的HTlc-囊泡复合分散体系。

英文摘要：

The spontaneous formation of vesicle induced by charged solid nanoparticle was reported. When mixing 5.0g/L Mg3Al hydrotalcite-like compound （HTlc） sol and 0.02 mol/L surfactant solution of zwitterionic surfactant, dodecyl betaine （C12BE）, and anionic surfactant, sodium bis（2-ethylhexyl） sulfosuccinate （AOT）, with molar ratio of C12BE to AOT equal to 3： 2, it was found that Mg3Al HTIc nanoparticles with structural positive charges may induce spontaneous formation of vesicles in the volume ratio range of the HTIc sol to the surfactant solution from 1：9 to 4 ：6, and a stable HTlc-vesicle composite was formed. The obtained HTlc-vesicle composite was characterized by negative-staining TEM and dynamic light scattering. Some HTIc nanoparticles were possibly enveloped in vesicles.
