The surface tension of the mixtures of cationic-anionic hydrocarbon-fluorocarbon surfactants composed of octyltriethylammonium bromide (C₈H₁₇N(CH₂CH₃)₃Br, C₈NE) and sodium perfluorobutane sulfonate (C₄F₉SO₃Na, C₄F) with different molar ratios was measured. The cmc,γ_cmc, total adsorption amount, the compositions of surface adsorption layers at different surface tension values and the micell composition at cmc calculated by means of Gibbs-Duhem equation were obtained. The molecular interaction parameter β^m and the micell composition after cmc were estimated via the regular solution theory. It shows that the cmc of each of C₈NE-C₄F mixtures was far smaller than that of individual component, which is consistent with the large negative value of β^m and thus there are strong molecular interactions in micelle. However, the γ_cmc values of C₈NE-C₄F mixtures were not changed greatly as expected when compared with single C₄F(γ_cmcwas decreased by 24 mN/m), which might be attributed to the asymmetry between C₈NE-C₄F chains and some C₈NE chains partially bending and covering the terminal CF₃ group of C₄F on the surface. In the surface adsorption layer,the fluorocarbon surfactant was rich-collected compared with the bulk solution. Even for those systems with C₈NE in greatly excess, the composition of surface adsorption layer was just around equimolar; while for those systems with C₄F in excess, the content of C₄F in the surface adsorption layer was a little larger than that in solution.The composition of surface adsorption layer moved further to the C₄F side with the decrease of surface tension. The micell composition at cmc was favorable to the formation of C₄F-richer micelle with the increase of C₄F content in bulk systems. For those systems with C₈NE in great excess, the micell composition at cmc was around equimolar. The micell composition after cmc was approximately equimolar, which might be due to the predominant electrostatic interactions. It is consistent with the phenomenon that the mixture tended to precipitate when the concentration exceeded a certain amount after cmc.
