Morphological Changes and Relaxations in Monolayers

Direct evidence has been presented for condensed phase formation in adsorbed monolayers at surfactant solution surfaces, which is quite the same as phase transitions from expanded to condensed phases in spread monolayers by compression. It thus follows that there is no clear boundary between adsorbed and spread monolayers. However, there are many different modes of relaxation in spread monolayers ouing to the greater non-equilibrium nature of spread monolayers during compression compared to adsorbed monolayers.
