Alternate layer Langmuir trough

Figure 12.13 Alternate layer Langmuir trough showing the substrate attached to the rotating drum (R). All other symbols have the same meaning as in Figure 12.11.

Figure 3.5 (a) An example of a constant perimeter alternate-layer Langmuir trough showing fixed central barrier (FB) and the motor-driven rotary mechanism (R). Also shown are the barrier ribbon (B), the barrier drive motors (BD) which are attached to the movable barriers (MB), the surfece pressure monitors (W and II), and the substrate (S). (b) Also shown is the alternate layer molecular architecture realizable using the alternate layer technique. 

Great interest has led to the development of Langmuir troughs with various meehanisms for the LB deposition of, for example, alternate layers of two different amphiphiles. In addition, techniques have been developed for overcoming problems related to the deposition of a second metal layer on top of a LB film already deposited on a metal substrate.
