Polysilanes have been recognized as being a new class of functional polymers, characterized by as-conjugated Si backbone and an ultraviolet (UV) photodecomposition due to the photochemical nature of the Si-Si bonds. The formation of Si-O-Si and Si-OH bonds due to UV photodecomposition in air induces changes in the nature of polysilane films, such as their wettability or swelling with water. It was known that UV-exposed polysilane film could be selectively dyed by simply soaking it in an aqueous cationic dye solution, using a specific interaction between cationic dyes and Si-OH moieties formed by UV photodecomposition.In this study, from the view point of exploiting the further application of polysilanes, we have tried to fabricate a convex microlens array of cationic polymer colloids to a desired size on polysilane films patterned by UV-light irradiation utilizing the ionic interaction between the Si-O^-units and the cationic polymer colloid. In addition, microlens arrays are required … More in many optical applications and in digital optical imaging systems. By soaking in an aqueous cationic polymer colloids solution followed by the heat-treatment to reflow the deposited polymer (the electroless polymer coating), we have successfully demonstrated an array of microlenses of 10 jam in size. In order to control the amount of polymer deposition, also, the alternating deposition technique of anionic and cationic polymer colloids was significant. With this method, the microlens array would be obtained easily on any substrates.On the transparent ITO (Indium tin oxide) covered with a polysilane film patterned by UV-light irradiation, moreover, an array of the colored (blue and green) refractive microlenses (10μm in size) was successfully fabricated using the electro-deposition of a colored polymer colloids solution.From now, we will carry out investigations into the fabrication of an electrically functional microlens array.These results obtained here would offer new avenues in developing practical applications of polysilanes appeared as a new class of functional polymers.

聚硅烷被认为是一类新型的功能聚合物，其特征在于具有共轭Si骨架和由于Si-Si键的光化学性质而产生的紫外（UV）光分解。由于在空气中UV光分解而形成的Si-O-Si和Si-OH键引起聚硅烷膜的性质的变化，例如它们的润湿性或与水的溶胀。利用阳离子染料与紫外光分解形成的Si-OH基团之间的特异性相互作用，将紫外光照射的聚硅烷膜简单地浸泡在阳离子染料水溶液中，可以选择性地染色。我们尝试在通过UV图案化的聚硅烷膜上制造所需尺寸的阳离子聚合物胶体的凸微透镜阵列，利用Si-O2-单元和阳离子聚合物胶体之间的离子相互作用进行光照射。此外，还需要微透镜阵列 ...更多信息 在许多光学应用和数字光学成像系统中。通过在阳离子聚合物胶体水溶液中浸泡，然后进行热处理以回流沉积的聚合物（无电聚合物涂层），我们已经成功地展示了尺寸为10果酱的微透镜阵列。为了控制聚合物的沉积量，阴离子和阳离子聚合物胶体的交替沉积技术也是重要的。这种方法可以在任何衬底上方便地制作微透镜阵列。此外，还可以使用由通过UV光照射图案化的聚硅烷膜覆盖的着色的氧化铟锡（Indium tin oxide）的阵列。（蓝色和绿色）折射微透镜利用彩色聚合物胶体溶液的电沉积法成功地制备出了尺寸为10μm的高分子膜。我们将进行电性功能微透镜阵列的制作研究，所得结果将为聚矽烷这类新型功能高分子的实际应用提供新的发展方向。少
