Abstract:
An apparatus for forming thin organic films includes a plurality of water tanks (11, 12, 13) each containing water. Monomolecular films of different amphiphatic organic molecules are developed on the surfaces of the liquid in water tanks respectively. A work (48) is dipped into and raised out of a desired water tank, by a driving device (50), in a direction substantially perpendicular to the liquid surface. It is arranged that the monomolecular film is adhered to the surface of the work in only one of the steps of dipping and drawing up the work. It is also arranged that the work is dipped into and raised out of the developing region in a predetermined direction with respect to the monomolecular film.
Abstract:
An organic film forming apparatus includes a trough (11) storing water therein and a work drive device (50) for moving a work (48) with respect to the trough. The surface of the water is partitioned by a rod (25) into a first developing region (11a) on which a monomolecular film (21) is developed and a second developing region (11b) on which no monomolecular film is developed. The work is moved by the device through the developed monomolecular film so as to adhere the film on the surface of the work. The device has a holding mechanism (54) which has a holding portion (70, 72) engaged with the work, and which holds the work so that when the work passes through the developed monomolecular film, the holding portion is away from the film or passes through the film after almost the entire work passes through the film.
Abstract:
An apparatus for forming thin organic films includes a plurality of water tanks (11, 12, 13) each containing water. Monomolecular films of different amphiphatic organic molecules are developed on the surfaces of the liquid in water tanks, respectively. A work (48) is dipped into and raised out of a desired water tank, by a driving device (50), in a direction substantially perpendicular to the liquid surface, so that the monomolecular film in the water tank is adhered on a work surface. The work is transported by a transporting device (52) to a position above another water tank, through an area lying above the water tanks. Then, the work is dipped into and raised out of the other water tank, by the driving device, in a direction substantially perpendicular to the monomolecular film, so that another monomolecular film is adhered on the monomolecular film already formed on the work surface.
Abstract:
Method and apparatus for continuously forming and depositing a layer of monomolecular amphiphilic molecules on a substrate. The apparatus of the present invention includes static mechanical means comprising a pump which is supported outside the lower portion of the tank (310) and connected by conduits to compartment (310a) which is designed as a continuous chute around compartment (310b). It is in compartment (310b) that the compressed monomolecular layer films are deposited onto a substrate. The water flows in the direction indicated by arrows. The pump pulls the transport liquid through a conduit and out of compartment (310b), and pushes said liquid through other conduits and into compartment (310a) which is separated from compartment (310b) by continuous chute (310d). The compartment (310c) receives the monomolecular layer solution.
Abstract:
Une cloison (6) sépare une cuve en deux compartiments (2, 4), des couches monomoléculaires de deux substances différentes se trouvant à la surface du liquide dans chacun des compartiments (2, 4). Deux ensembles de deux lames élastiques (26, 28 et 27, 29) sont disposés au voisinage de la surface du liquide au niveau d'une ouverture (7) dans la cloison (6). Une tige (14) permet de transférer le substrat (12) d'un compartiment à l'autre à l'intérieur du liquide en écartant lesdites lames élastiques. La tige (14) est également mobile verticalement afin que le substrat (12) puisse traverser la surface du liquide.
Abstract:
PURPOSE:To prevent the mixing of an impurity while improving and equalizing molecular-axis orientation by forming a monomolecular film on the interface between a water layer and an organic solvent layer of two phase systems, an upper layer thereof consists of water and a lower layer thereof an organic solvent, which is heavier than water and does not mix with water. CONSTITUTION:An organic solvent 12, which is heavier than water and does not mix with water, is introduced up to the center of a frame 15 fitted in approximately half height of a water tank 11 in the lower section of the water tank. The frame 15 functions as the change of an area 16 surrounded by the frame. When pure water 13 is added slowly onto the organic solvent 12, the interface 14 between the organic solvent and water is formed. When a material for a monomolecular film is dropped to the interface 16 surrounded by the frame 15, molecules form in lines while hydrophilic groups are directed toward the water layer on the interface 14 between the organic solvent and water. When the area surrounded by the frame 15 is reduced gradually, intermolecular interaction is intensified, and a two-element solid film, which has high molecular orientation and into which impurities do not mix, is formed. A monomolecular laminated film is obtained by transferring the monomolecular film 17 to the surface of a clean substrate as the state of the solid film is kept as it is.
