Physicochemical aspects of the disperse sam systems foaming process

Results of the presented work allow us to draw such conclusions, inherent in the general vector of the research results in this field, as, for example, that size decrease below certain threshold value leads to the considerable changing of physicochemical and mechanical properties and especially foam properties. Such effects show itself when the sizes are about 100 (110+2 нм) and less of nanometers. In presented researches this size has been reached, and hence the matter concerns mentioned characteristics of cellular bodies among which are, in our opinion, foam films of the molecules of studied surface-active materials (SAM) foam makers. In particular it was determined that the size of the foam film itself of SAM foam makers may come to several orders of nanoparticle size, i. e. ~110-7. 110-5 nm, and the size of the foam maker particle - up to several dozens of angstorm. Thus, cellular bodies analysis has revealed the necessity to take into consideration not only their composition and structure but also dispersivenes.
