摘　　要：季铵盐二聚表面活性剂 C1 2 -s-C1 2 · 2 Br(s=2 ,3 ,4,6)和非离子表面活性剂 TX-1 0 0在水溶液中生成混合胶团。其临界胶团总浓度 cmc T值介于二元复配体系中各组分的临界胶团浓度 cmc01 和 cmc02 之间。当添加少量非离子型表面活性剂 (在水溶液中的摩尔分数α2 =0 .1 )时 ,混合胶团中 TX-1 0 0的摩尔分数≥ 0 .4;随着溶液中非离子型表面活性剂含量的增大 ,混合胶团中逐渐以 TX-1 0 0成分为主。The mixed micelles were formed from alkylene-α,ω-bis(dodecyldimethylammonium bromide) surfactants, C_ 12-s-C_ 12·2Br(s=2,3,4,6), and the nonionic surfactant Triton X-100 in aqueous solution. The values of the total critical micelle concentration(cmc_T) were found to be between cmc0_1 and cmc0_2, i.e. the critical micelle concentrations for individual surfactant 1 and surfactant 2, respectively. Addition of nonionic surfactant in 0.1 molar fraction(α_2) in the bulk solution results in the molar fraction of Triton X-100 in the mixed micelle ≥0.4. With further increase of α_2, Triton X-100 composition in the mixed micelles became predominant.
