ABSTRACT
The free liquid films formed between the bubbles of foams or the droplets of emulsions quite often contain solid particles, either from their original composi tion or as impurities. Examples of similar systems containing solid particles inside thin films are the so-called Pickering emulsions [1-4], some food emulsions con taining protein aggregates [5], ice creams, as well as latex and metallic dyes and coatings. A phenomenon of particular interest and importance caused by micelles inside foam films is the stratification [6-10]. It has been shown that the stratifica tion is a major factor of stabilization of liquid films in emulsions and foams and that this phenomenon can also be observed with nanometer-sized latex particles and proteins [11-13].
