摘　　要：以离子液体[MEIM]^+[ES]^-为晶体生长调控剂,采用简便的电化学方法合成了特定形貌的氢氧化镁纳米结构薄膜。对影响电沉积氢氧化镁薄膜的合成参数(如离子液体的含量、沉积电位和沉积时间)进行了研究,并分别用电镜、X射线衍射和热分析技术对所得氢氧化镁薄膜的形貌和热稳定性进行了表征。此外,该电化学过程可望推广到制备其它形貌独特和性能奇特的纳米/介观结构。The thin films are prepared with magnesium hydroxide nanostructures and a well-defined morphogenesis in relatively large quantities by electrochemical approach using ionic liquid（[MEIM]^＋ [ES]^-） as crystal growth modifier. The influences of synthesis parameters on the morphological characteristics of magnesium hydroxide thin films deposited from nitrate bath are studied, such as content of ionic liquid, applied potential and duration. The morphology and thermal stability of the obtained magnesium hydroxide thin films are characterized using electron microscopy,X-ray diffraction and thermal analysis. In addition, this electrochemical process may provide a versatile and mild road for fabricating nano-/mesostructures with unique morphologies and exotic properties.
