Development of a practical instrument for preparing complex LB films of high quality fully automatically.

Langmuir-Blodgett （LB）薄膜是通过在合适的固体衬底上连续沉积单层膜而制成的。它们被认为是分子有序的超薄薄膜。然而，近年来人们发现LB膜中存在着许多分子秩序缺陷。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膜的商业应用的实用化。本次资助的科研目的是研制一种全自动制备高质量复杂LB膜的实用仪器。这台仪器可由两台微型计算机控制。一台微机精确控制两种单层膜的表面压力，以沉积复杂的LB膜。另一台微机通过集成Peltier元件自由控制Langmuir槽内的水面温度，并控制固体衬底在沉积过程中的复杂运动。该仪器研制成功，获得了许多高质量的单层膜和LB膜。参考本文背面这两年我们所报道的论文，特别是两篇关于单层的A-T异构体的论文，这些异构体导致单层和LB膜致密化，以减少LB膜的缺陷。为了更好地理解庞大的控制程序，将仪器的控制程序分成若干块。任何想要使用该仪器的人都可以通过控制程序的菜单系统来使用它。在项目的第二年，我们开发了Brewstar角度干涉显微镜（BAIM），可以直接观察水面上的不溶性单层。法国在去年夏初首先报道了这一仪器。由于其他实验仪器很难直接观察到水面上的不溶性单分子层，所以我们将项目内容改为研制这台仪器。该显微镜与新开发的可自由控制温度的Langmuir槽相结合，将成为评估单层和LB膜质量的有力工具。少

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
