ABSTRACT
This chapter describes a short description of the different experimental techniques which are used in the field of mono- and multilayers. Most of them give information about equilibrium properties, although they have the corresponding dynamic counterpart. Langmuir monolayers are typically prepared by spreading a small amount of the surfactant solution onto a bare water–air or water–oil interface, chloroform being the preferred solvent when possible. The characterization of the different phases and the unambiguous location of the phase boundaries cannot be achieved just from the mere isotherms, and some other different techniques have been used to study the phase behavior and the meso- and microscopic structures of the monolayers. Other classical electrochemical techniques which can be applied to monolayers is conductivity, in the case of monolayers is the lateral conductance the magnitude of interest.
