摘　　要：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 properties in the blend systems of inulin quaternary ammonium salt and sodium dodeeyl sulphate （SDS） were investigated. The synergic parameters of the two components in both blend micelles and surface adsorption layers were obtained through calculation. Results show that there is a strong synergic effect in the blend systems. The surface chemical performance of the blend systems is significantly better than that of the monosurfactant system. When n （inulin quaternary ammonium salt）：n（SDS） = 8：2, the critical surface tension （γcMc） and the critical micelle concentration （CMC） are 23.81 mN/m and 2. 81μmoL/L respectively.
