Abstract:
A process for producing a thin layer of at least one amphiphilic compound on a carrier is described, in which an at least partially oriented layer of molecules of an amphiphilic compound is produced by compression and expansion at the interface between a fluid and a polar liquid, and a solid carrier is moved through the layer so that the layer is transferred thereto. For this purpose, a directional flow of the polar liquid which contains amphiphilic molecules in solution or as insoluble molecules in a spread form on the surface is generated in an approximately horizontally located channel and the flow is dammed at a barrier which is located at the fluid/polar liquid interface. The flow velocity and, if appropriate, the concentration of the amphiphilic molecules are selected such that a layer of amphiphilic molecules is continuously formed by compression in front of the barrier at the fluid/polar liquid phase boundary. An apparatus suitable for this purpose comprises a horizontally arranged flow channel for taking up a liquid, a barrier arranged at the phase boundary for damming the surface flow in the channel, a device for generating the flow of the liquid and a device for controlled slow immersion of a solid carrier into the channel and emergence therefrom in proximity to the weir.
Abstract:
A curved surface shaping apparatus has a liquid tank for developing a monomolecular film on the surface of liquid contained in the liquid tank, a jig for holding a base member to be shaped, and moving means for moving the base member held by the jig with the shaped surface of the base member intersecting the liquid surface. A curved surface shaping method comprises a step of moving a base member to be shaped relative to a liquid surface on which a monomolecular film is formed, with the liquid surface and the shaped surface of the base member intersecting each other.
Abstract:
The present invention relates to a process and to an apparatus for producing alternate monomolecular layers. In per se known manner, a substrate is passed through the surface of a liquid contained in a vessel and over which has previously been spread a monomolecular layer of a given substance. According to the invention, the vessel is subdivided into two compartments. A monomolecular layer is deposited on the surface of the liquid contained in each of the compartments. The latter are arranged in such a way that there can be no contact between the monomolecular layers in each of them and the substrate is alternately moved between the compartments.
Abstract:
PURPOSE:To shorten time and labor to cumulate a film, by providing with liquid-flow generating means in the liquid bath for expanding film forming molecules and a barrier which encloses the film and which is removably contacted onto the liquid surface, and by controlling surface pressure of the monomolecular film so as to attain a desired surface density. CONSTITUTION:On forming a thin film bearing optical functions which a logical device, a memory device and a photoelectric converting device, etc. have, the thin film consisting of organic molecules is formed with a monomolecular cumulation method. Water from a water flow generating means 7 is flowed into a water bath 3, and the water surface is dammed by a barrier 8 being placed on the water bath 3 so as to overflow the excess water. Next, solution of 0.1ml in which stearic acid is being melted in a solvent of chloroform at a rate of 1X 10 M/l is dripped onto the dammed water surface in the upstream dripping area 9 at a rate of 20cm/sec to produce a cumulated film on the cumulation area 10 in the monomolecular film 2 forming area near the barrier 8. When the monomolecular film remains, it is flowed away by raising the barrier 8 and then the next operation proceeds.
