Langmuir-Blodgett film deposition with hydrophobic substrate molecules

In this way (multi)layers, referred to as Langmuir-Blodgett films or, for short, LB films, are formed with alternating head-head and tail-tail orientations of the surfactant molecules. This type of transfer in which a monolayer is deposited during each passage of the substrate through the interface is called F-transfer. It follows that with hydrophihc supports at the end of each completed cycle films containing an odd number of layers are deposited, whereas for hydrophobic surfaces an even number of layers are transferred.
