DYNAMIC BEHAVIOUR OF THE LANGMUIR MONOLAYER AT THE AIR/WATER INTERFACE

Ján Vajda - Martin Weis - Drahoslav Barančok - Július Cirák - Pavol Tomčík

   The experimental results of the measurements of displacement current generated during stearic acid monolayer compression are analyzed by means of the model based on analogy with non-ideal gas of polar rod-like molecules, assuming Boltzmann statistics of orientational distribution. The experimental data are compared with our theory and the following experimental steps as well as further theoretical analysis are suggested.

Keywords: Langmuir film, non-ideal gas approximation, order parameter
