Novel fabrication of fine materials using liquid phase deposition process with Heterogeneous liquid-liquid interface

金属氧化物薄膜的液体相位沉积（LPD）在液体界面上进行了研究。就在LPD反应的开始之后，存款一直被观察到液体接口。储存grew two-dimensionally into一部自立的电影，厚度为1·m，面积为上限。1毫米，没有任何固体材料。自立电影是用不对称形态学制成的，它是由液体-液体界面侧面的平面表面和相对地通过体积解决方案侧面的表面组成的。该结构是由拉曼光谱表征的，证实可迁移的钛氧化物氟化物（NH_4TiOF_3）首先沉积在液体接口上，而在哪一种甲烷型钛氧化物（TiO_2）沉积了两秒钟以形成不对称性生物结构。

The liquid phase deposition (LPD) of metal oxide thin films at the liquid-liquid interface was investigated. Just after the start of the LPD reaction, depositions were observed continually at the liquid-liquid interface. The deposition grew two-dimensionally into a self-standing film with thickness of 1・m and domain size of up to ca. 1mm without any solid substrates. The self-standing film was formed with asymmetrical morphology, which consisted of flat surface on the side of the liquid-liquid interface and relatively rough surface on the side of the bulk solution. The structure was characterized by Raman spectroscopy, confirming that metastable ammonium titanium oxide fluoride (NH_4TiOF_3) was first deposited at the liquid-liquid interface, on which anatase-type titanium oxide (TiO_2) was deposited second to forming the asymmetrical bilayer structure.
