项目摘要

Langmuir-Blodgett (LB) films are made by successive deposition of monolayers on the water surface onto suitable solid substrates. They are believed to be molecularly orderd ultra-thin films. Recently, however, it becomes clear that there are so many defects of molecular order in LB films. This in the reason that we can not realize practical of commercial use of LB films in spite of the potential possibilities of LB films in many fields. What we intended to develop by this grant-in-aid for scientific research is a practical instrument for preparing complex LB films of high quality fully automatically. This instrument can be controlled by two microcomputers. One microcomputer controls surface pressures of two kinds of monolayers precisely to deposit complex LB films. Another microcomputer controls the tmperature of the water surface in the Langmuir trough freely by using integrated Peltier elements and also controls the complicated movement of solid substrates during deposition of the co … More mplex LB films. This instrument could be developed successfuly and many results leading high quality monolayers and LB films have been obtained by this instrument. Refer papers on the back side of this paper, reported by us in these two years, especially two papers on the A-T isobers of monolayers which lead densification of monolayers and LB films to reduce defects in LB films. The control-program of the instrument is divided into some blocks to get good perspective of the huge control-program. Whoever wishes to use this instrument can use this by menu-system of the control program. In the second year of the project term, we have developed the Brewstar Angle Ineterference Microscopy (BAIM) which can observe insoluble monolayers on the water surface directly. This instrument have been reported first by French at the beginning of last summer. We changed the content of the project to develped this instrument because it has been very difficult to observe insoluble monolayers on the water surface directly by other experimental instruments. This microscopy will be a powerful tool for estimating quality of monolayers and LB films by combination with the newly develped freely temperature controllable Langmuir trough. Less

LB膜是通过在合适的固体基底上的水表面上连续沉积单层来制备的。它们被认为是分子有序的超薄膜。然而，最近人们发现LB膜中存在大量的分子有序缺陷。这是因为尽管LB膜在许多领域具有潜在的可能性，但我们仍然无法实现LB膜的商业化应用。我们打算通过这项科研资助开发的是一种实用的仪器，用于全自动制备高质量的复杂LB膜。该仪器可由两台微机控制。用一台微机精确控制两种单分子膜的表面压力，沉积出存款复杂的LB膜。另一台微机利用集成的珀耳帖元件自由控制朗缪尔槽内的水面温度，并控制沉积过程中固体基质的复杂运动。 ...更多信息复合LB膜。该仪器已研制成功，并获得了许多高质量的单分子膜和LB膜。参考了我们近两年来发表的论文，特别是两篇关于单分子膜的A-T异构体导致单分子膜和LB膜致密化以减少LB膜中缺陷的论文。对仪器的控制程序进行了分块设计，使庞大的控制程序得到了较好的透视。任何希望使用该仪器的人都可以通过控制程序的菜单系统使用该仪器。在项目的第二年，我们开发了Brewstar角干涉显微镜（BAIM），可以直接观察水表面上的不溶性单分子膜。这种仪器在去年夏天初由法国人首先报道。由于用其它实验仪器直接观察水表面的不溶性单分子膜很困难，我们改变了项目内容，研制了这台仪器。这种显微镜将是一个强有力的工具，估计质量的单分子膜和LB膜结合新开发的自由温度可控的朗缪尔槽。少
