采用无表面活性剂的反相微乳液法合成了Mg 2Al-Cl层状双氢氧化物（LDH）纳米片。该微乳液由甲苯、异丙醇和水溶液作为分散相组成。通过双微乳液技术获得了LDH纳米片的水分散体。采用X射线粉末衍射、透射电子显微镜、扫描电子显微镜、原子力显微镜、傅里叶变换红外光谱、热重分析和元素分析等方法对LDH纳米片进行了表征。LDH纳米片由单个水镁石层组成，没有任何有机分子的负载。据我们所知，这是第一次报告的裸LDH单层水分散体直接获得。LDH单分子膜可用作LDH基功能材料的结构单元。
The synthesis of Mg2Al-Cl layered double hydroxide (LDH) nanosheets in a surfactant-free reverse microemulsion is described. The microemulsion was composed of toluene, isopropanol, and an aqueous solution as the dispersed phase. An aqueous LDH nanosheet dispersion was obtained by a double-microemulsion technique. LDH nanosheets were characterized by X-ray powder diffraction, transmission electron microscopy, scanning electron microscopy, atomic force microscopy, Fourier transform infrared spectroscopy, and thermogravimetric and elemental analyses. The LDH nanosheets consisted of a single brucite layer without any loading of organic molecules. To the best of our knowledge, this is the first report of a naked LDH monolayer aqueous dispersion being directly obtained. The LDH monolayers can be used as building blocks for LDH-based functional materials.
