Abstract: For the continuous production of an ultra-thin, ordered layer of amphiphilic molecules on the surface of a polar liquid, an aligned flow of the polar liquid is generated in a channel, which polar liquid contains the amphiphilic molecules, dissolved or undissolved, on the surface in spread form. In the channel, a channel section with relatively high flow rate at the surface is provided, which section has a ramp which is arranged on the channel bottom and over which the polar liquid flows. Following this there is a channel section with a relatively low flow rate at the surface, in which channel section the flow is dammed at an obstruction with the liquid level constant over time, so that an ultra-thin, ordered layer of amphiphilic molecules continuously forms, as a result of flow compression, at the polar liquid/air phase boundary in these channel sections. The ramp over which the liquid flows is arranged so as to be movable.

Abstract: The prodn. of composite membranes comprises spreading a soln. of a polymer (I) in a volatile solvent on water. Allowing the solvent to evaporate, crosslinking the polymer and transferring the film obtd. to a supporting membrane. Also claimed is a composite membrane with polymer layer(s) on a porous base membrane, obtd. by this process. (I) is a polysiloxane which is pref. crosslinked via OH gps. on the polymer, with the aid of a bi-, tri- or tetra-functional silane with hydrolysable SiO- gps. as crosslinker (II), pref. triacetoxy-methyl-silane (TACMS), in the presence of a catalyst, pref. a tin salt. Alternatively, (I) may be a polymer contg. olefinic double bonds, which is crosslinked by irradiation. Pref. polymer layer is a protective layer of polysiloxane, crosslinked via OH gps. to a structure contg. units of formula Si(O-)4, R-Si(O-)3 or RR Si(O-)2 (with R, R = alkyl, phenyl or vinyl), or a silicone which is crosslinked by irradiation.

Abstract: of the disclosure: "Process and device for producing ultrathin layers and layer elements" In order to continuously produce an ultrathin, ordered layer of amphiphilic molecules on the surface of a polar liquid a directed flow of the polar liquid is produced in a duct which contains the amphiphilic molecules in dissolved or undissolved form on the surface in spread form. In the duct, a duct section having a relatively high flow rate on the surface and comprising a ramp which is arranged at the bottom of the duct and washed over by the polar liquid is provided. This is followed by a duct section having a relatively low flow rate on the surface, in which the flow is dammed up at an obstacle at a liquid level constant with time, so that an ultrathin, ordered layer of amphiphilic molecules is continuously formed in these duct sections at the polar liquid/air interface by compression of the flow. The washed over ramp is movable.
