Organic-inorganic film of several micrometers in thickness has been investigated. The films fabricated by dipping technique showed the remarkable cellular patterns, when such reagents as Ti, Zr alkoxides and silane coupling agent having amino groups (aminopropyltrimethoxysilane : APTS) were involved in the starting sol.In this investigation, to make clear the condition of on set of the cellular patterns, optical properties of the sol, observation of the film surfaces by laser microscopy and atomic force microscopy (AFM) have been carries out. The results were summarized as follows,(1) Moisture in the atmosphere is inevitable for the onset of the cellular patterns.(2) Along with the hydration-polymerization reaction, nanometer-sized particles were formed in the starting sol and they were grown with increasing the reaction time.(3) The 3-D image of the cell was obtained by the AFM observation. The cell was composed of the valley center surrounded by the mountain- like wall of few nanometer 〜hundred of nanometer. There were the relations between their clearness and the depth.(4) The formation mechanism of the cell in the hybrid film is : the first step is nanometer-sized particles (TiO_2, ZrO_2 or SiO_2 nanoparticles) generation in the starting sol, the second step is the flow of these nanoparticles by the Marangoni convection.

研究了当Ti、Zr醇盐和具有氨基的硅烷偶联剂（氨丙基三甲氧基硅烷：APTS）等试剂参与起始时，几微米厚的有机-无机薄膜显示出显着的泡孔图案。溶胶。在这项研究中，为了弄清楚细胞图案的设置条件、溶胶的光学特性、通过激光显微镜和原子力观察薄膜表面显微镜（AFM）结果总结如下：（1）大气中的水分对于细胞图案的形成是不可避免的。（2）随着水合聚合反应，形成纳米尺寸的颗粒。 (3)通过AFM观察获得细胞的3D图像。细胞由山谷中心和几纳米的山状壁包围而成。其清晰度与深度之间存在关系。(4)杂化膜中晶胞的形成机理是:第一步是纳米级粒子(TiO_2、ZrO_2或SiO_2纳米粒子)在膜中生成。从溶胶开始，第二步是这些纳米粒子通过马兰戈尼对流流动。
