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.

研究了几微米厚的有机-无机膜。当Ti、Zr的醇盐和硅烷偶联剂中含有氨基时，浸渍法制备的薄膜呈现出明显的胞状结构（氨丙基三甲氧基硅烷：本研究中，为了明确胞状图案的形成条件，溶胶的光学性质，用激光显微镜和原子力显微镜（AFM）对薄膜表面进行了观察。结果表明：（1）大气中的水分是胞状斑图形成的必然条件。(2)沿着水化-聚合反应，在起始溶胶中形成纳米尺寸的颗粒，并且它们随着反应时间的增加而生长。(3)通过AFM观察获得了细胞的三维图像。细胞由几纳米到几百纳米的山状壁包围着谷中心组成。它们的清晰度和深度有关系。(4)杂化膜中晶胞的形成机制为：第一步是溶胶中纳米颗粒（TiO_2、ZrO_2或SiO_2纳米颗粒）的生成，第二步是这些纳米颗粒通过Marangoni对流流动。
