| 摘 要： | 研究了酮撑联接的双季铵盐表面活性剂(WG04系列)的表面活性,考察了WG04/SDS、WG04/聚合物及WG04/聚合物/Na2CO3复合体系的协同效应。结果表明,WG04系列表面活性剂具有较高的表面活性,其水溶液的临界胶束浓度比传统离子表面活性剂低1~3个数量级。其中,WG04-12的cmc为8.9×10-4mol/L,γcmc为28.7 mN/m。复配体系的cmc比相应的WG04水溶液要低,获得明显的表面活性增益。

| Abstract: | Surface activity of bis-quaternary ammonium salt surfactant with keto group connection(WG04 series) and synergistic effect of compound systems including WG04/SDS,WG04/polymer and WG04/polymer/ Na2CO3 have been studied.Experimental results indicate that surfactant of WG04 series has much higher surface activity.Critical micelle concentration(cmc) of solution was lower than that of ordinary ionic surfactants for 1~3 order of magnitudes.The cmc of WG04-12 was 8.9×10-4 mol/L and its γcmc was 28.7 mN/m,cmc of compound system was lower than that of the corresponding solution of WG04.It acquires gain of surface activity significantly. |
