Abstract

The monomolecular layer is first formed from a solution of amphiphilic molecules by introduction of the solution on a liquid surface which is divided into at least two compartments by at least one rotatable and partly immersed horizontal member. The solvent is then removed and the horizontal member is driven in rotation so as to apply a predetermined pressure to said layer as this latter is transferred from one compartment to the next, the layer being finally deposited on a substrate. This a division of application Ser. No. 765,063, filed Feb. 2, 1977, now U.S. Pat. No. 4,093,757, issued June 6, 1978.
