| 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5.0 g/L带结构正电荷的Mg3Al类水滑石(HTlc)溶胶和0.02 mol/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.

| Abstract: | The spontaneous formation of vesicle induced by charged solid nanoparticle was reported. When mixing 5.0 g/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 HTlc nanoparticles with structural positive charges may induce spontaneous formation of vesicles in the volume ratio range of the HTlc 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 HTlc nanoparticles were possi-bly enveloped in vesicles. |
