PROCESS FOR PREPARING A THIN FILM AND APPARATUS THEREFOR
A process is disclosed for preparing a thin film having a large area. A casting solution comprising a film-forming material and a solvent is fed to the surface of a liquid substrate immiscible with the solution by utilizing a interfacial tension. Spontaneous spreading of the casting solution occurs...

| description | A process is disclosed for preparing a thin film having a large area. A casting solution comprising a film-forming material and a solvent is fed to the surface of a liquid substrate immiscible with the solution by utilizing a interfacial tension. Spontaneous spreading of the casting solution occurs across the surface of the liquid substrate and evaporation of the solvent produces the thin film on the liquid surface which is continuously collected. The feed of the casting solution to the surface of the substrate comprises at least either a material which shows selective wettability for the casting solution in preference to the liquid substrate or a structure capable of developing capillarity. |
