Résumé : |
Here we study the influence of alkaline cations on the self-assembly of cetylpyridinium chloride and cetylpyridinium nitrate. It is known that the anionic counterions have a strong influence on the solubility and self-assembly properties of cationic surfactants. However, in this paper we will show that monovalent cations have also an influence which is weaker but detectable. Scattering techniques (X-Ray, light) were used to obtain structural information about the aggregation as a function of the temperature and the ionic strength. The results are interpreted in terms of ion pair adsorption at the micellar interface, depending on the ionic strength. |
