考察了菊粉季铵盐与十二烷基硫酸钠(SDS)复配体系的表面化学性质,计算了二者在混合胶束和表面吸附层中的协同作用参数。结果表明,复配体系的表面化学性能明显优于单一体系,在混合胶束和表面吸附层中都表现出强烈的协同效应。当n(菊粉季铵盐)∶n(SDS)=8∶2时,复配体系的临界胶束浓度(CMC)和临界表面张力(γCMC)分别为2.81μmol/L和23.81 mN/m。
The surface chemical properties of inulin quaternary ammonium salt and sodium dodecyl sulfate (SDS) complex system were investigated. The synergistic parameters between the mixed micelles and the surface adsorption layer were calculated. The results showed that the surface chemical properties of the complex system were significantly better than that of the single system, and the synergistic effect was observed both in the mixed micelles and the surface adsorption layer. The critical micelle concentration (CMC) and critical surface tension (γCMC) of the composites were 2.81μmol / L and 23.81 mN / m when n (SDS) = 8: 2.
