一、LANGMUIR BLODGETT多分子层Langmuir Blodgett多分子层是由不溶物(两亲分子)的单分子层按一定规律组成的集合体。此类实验一般是在Langmuir槽上进行的。图1是其示意图。图中A表示飘浮于液体表面的一个栅栏,可以通过与之相连接的天平记录膜中表面压的变化,B表示可移动的活塞,可用之改变膜的表面积。实验方法如下:在Langmuir槽中放满液体,于其表面上铺展 First, LANGMUIR BLODGETT multi-molecular layer Langmuir Blodgett multi-molecular layer is composed of insolubles (amphipathic molecules) of the monolayer by a certain regularity of the assembly. Such experiments are generally performed on Langmuir troughs. Fig. 1 is a schematic view thereof. In the figure, A shows a fence floating on the surface of the liquid, the change of the surface pressure in the film can be recorded by the balance connected thereto, and B shows the movable piston which can be used to change the surface area of ​​the film. The experimental method is as follows: fill the Langmuir tank with liquid and spread it on its surface
