FUNCTIONAL THIN FILM WITH MONOMOLECULAR FILM ON BOTH FACES AND CONTINUOUS PREPARATION THEREOF

摘要

PURPOSE:To obtain a continuous functional thin film having continuous monomolecular films on both faces and a method for preparing continuously it. CONSTITUTION:A continuous functional thin film 2 being movable upward or downward is provided between two developing soln. tanks each for forming a monomolecular film being placed in parallel in a distance being a little wider than the thickness of the functional thin film and the first monomolecular film and the second monomolecular film are continuously formed by feeding continuously volatile solvent soln. of the first and the second monomolecular film forming substances respectively on the liq. faces 51 and 52 of both developing liq. tanks. The first and the second monomolecular film is continuously transferred on each face of the functional thin film 2 moving upward or downward to prepare continuously the functional thin film having the monomolecular films on both faces.
