A theoretical model was created for this mechanism and compared with the experimental results. Both the experimental and theoretical results support the proposed mechanism and evaluate the importance of the individual steps. It seems that the decisive step is the regenration of the zwitterionic form of the phospholipid at the interface, ensuring stability of the film in time and its continuous functioning. Workplace J.
