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.
Claims18
A device for forming and depositing a monomolecular layer of amphiphilic molecules on a substrate which comprises
- (1) a tank for containing a liquid,
- (2) at least one cylinder which is rotatably mounted on a horizontal axis and adapted to be partly immersed in said liquid, said cylinder or cylinders being intended to provide a separation which divides the surface of said liquid into at least first and second adjacent isolated compartments,
- (3) means for feeding a solution of amphiphilic molecules to the liquid surface of said first compartment, and
- (4) means for causing said cylinder or cylinders to rotate about their own axes thereby to transfer a monomolecular layer from the liquid surface of said first compartment to at least the liquid surface of said second compartment.
A device for forming and depositing a monomolecular layer of amphiphilic molecules on a substrate which comprises
- (1) a tank for containing a liquid,
- (2) at least one horizontal torus which is adapted to be partly immersed in said liquid, said torus or tori being intended to provide a separation which divides the surface of said liquid into at least first and second adjacent isolated compartments,
- (3) means for feeding a solution of amphiphilic molecules to the liquid surface of said first compartment, and
- (4) means for causing said torus or tori to rotate about their mean circle thereby to transfer a monomolecular layer from the liquid surface of said first compartment to at least the liquid surface of said second compartment.
