ABSTRACT:
An apparatus and process for producing organic monomolecular or multilayer films continuously comprises a tank having a spreading region (S) for spreading a material to form a monomolecular film, a compression region (C) for compressing the material on the liquid surface to form the monomolecular film and a deposition region (D) where the monomolecular film is deposited on a substrate. Means is provided to cause liquid to flow continuously from the spreading region to the deposition region through the compression region. A first control means is provided to maintain the liquid level in the deposition region D at a predetermined level. A second control means is provided for regulating the surface pressure of the monomolecular film at a predetermined value. Fluid flow through the apparatus is regulated so that the thickness of the liquid flow in the region C is less than thickness of the liquid flow in the regions S and D, and a decoupling region DS is provided between the region S and the region C. The provision of the decoupling region DS permits more stable film production.
