项目摘要

We have succeeded to fabricate the thin films having micro stripped patterns of 10 micron which show eye-angle dependency on light transparency with keeping 90 % light transparency as average. This micron order structure is not due to micro phase separation but due to self-organization during photoreaction. The applications are widely expected as following ; eye-angle regulated films, diffusion films of liquid crystal displays, and light guiding films. In order to improve the performance of light transparency and thinner films, the mechanism of self-organization during photoreaction has been studied. The followings are clearly found.(1)The structure formation takes place under moderate light intensity.(2)The structure formation takes place under a certain concentration of radical reaction initiator.(3)The ordered stripped patterns with modulation of photoreaction conversion are observed by the analysis of micro Raman.(4)The structures are fixed at maximum of photoreactions after becoming gel.Our understanding of the mechanism is discussed below by thinking the photoreaction. The most realistic mechanism proposed here was that micro gels produced by photoreaction enhance the inhomogeneous light intensity because of light scattering. The kinetic constant of photoreaction in terms of light intensity shows a sigmoid function having an inflection point which is responsible for splitting the light intensity distribution into strong and weak fields.
我们成功地制备了具有10微米微条纹图案的薄膜,该薄膜的透光率平均保持在90%,并表现出眼睛角度对透光率的依赖。这种微米级的有序结构不是由于微相分离,而是由于光反应过程中的自组织。广泛预期的应用如下:角度调节膜、液晶显示器扩散膜、导光膜。为了提高光透明性能和薄膜厚度,研究了光反应过程中的自组织机理。下面是清晰的发现。(1)中等光照强度下结构形成。(2)在一定浓度的自由基反应引发剂下形成结构。(3)通过微拉曼分析,观察到光化学转化的有序条纹。(4)凝胶化后,光反应最大时结构固定。下面我们通过思考光反应来讨论我们对机理的理解。本文提出的最现实的机制是光反应产生的微凝胶由于光散射而增强了光的不均匀性。光反应的动力学常数和光强的关系表现为具有拐点的s型函数,该拐点负责将光强分布划分为强场和弱场。
