Abstract

A thermodynamic theory for ideally mixed rodlike micelles is used to predict the size distribution and mean aggregation number of mixed dihexanoylphosphatidyl-choline (diC6PC) and diheptanoyl-phosphatidylcholine (diC7PC) micelles. The mixed diC6PC and diC7PC micelles are also studied by small-angle neutron scattering. The measured neutron scattering spectra are analyzed to give the size distribution and mean aggregation number of the mixed micelles by using indirect transform method. The experimentally determined mean aggregation number of the mixed micelles is in general in good agreement with that predicted by the thermodynamic theory. The addition of small amounts of diC6PC to a 10 mM diC7PC solution is found to make the micelles become significantly smaller and the addition of small amounts of diC7PC to a 10 mM diC6PC solution is found to make the micelles grow slightly larger.
