たかたちで、二分子層配列させた超薄膜のことである。Biological membranes, which are places where biological functions are expressed, play a variety of important roles, such as recognition of information from the outside, transmission of information into the membrane, and conversion and transport of substances. Therefore, the development of artificial membranes is extremely important for the production of materials and devices that mimic biological systems. Various types of such artificial membranes have been considered, such as polymer cast membranes and Langmuir-Prodgett (LB) membranes, but as a biological membrane model, a bilayer membrane system is the closest to a biological membrane. This bilayer membrane is an ultra-thin film in which two layers of amphiphilic molecules such as phospholipids are arranged in small pores in a substrate in water, with the alkyl chains of the hydrophobic parts facing each other. It is.

Examples include an electrolytic polymerization method in which a substrate is immersed in a solution of an organic compound and electrolytically polymerized using the substrate as an electrode to form an organic thin film on the surface of the substrate. Among these methods, the electrolytic polymerization method is preferable from the viewpoint of controllability of the thickness of the thin film and stability of the thin film. Examples of organic thin films formed by electrolytic polymerization include polystyrene, polypyrrole, polythiophene, and the like. The organic thin film itself may be hydrophobic, or its surface may be subjected to hydrophobic treatment.
