Indicative evidence for coexistence of long and short polymer-like micelles in lecithin organogel from rheological studies
A jelly-like phase, which is separated from the homogeneous lecithin organogel after exceeding the critical amount of water, has been studied by an oscillatory rheology. An interpretation of rheological parameters taken from the chemistry of polymer blends enabled us to suggest that the separated organogel consists of a mixture of at least two types of rather monodisperse polymer-like micelles differing by their length.
