中文摘要：

评价了一种阳离子型双子表面活性剂溴化-1，4-二[（3-十二烷氧基酰基）吡啶]丁烷（NAE12—4—12）与普通阴离子表面活性剂十二烷基苯磺酸钠、聚丙烯酰胺（PAM）和聚丙烯酸（PAA）的协同作用．实验结果表明NAE12—4—12：SDBS=3：7时，复配效果最好，混合体系的cmc降至0．0031mmol／L，相对于纯NAE12—4—12双子表面活性剂溶液，降低2个数量级；γcmc降低至27．8mN／m，比纯水的张力低44mN／m；该表面活性剂和PAM、PAA的临界缔合浓度cac高于NAE12—4—12的临界胶束浓度cmc，同时混合体系的γcac远低于0．01％PAM及PAA溶液的1值，说明NAE12—4—12与这两种聚合物之间存在较强的相互作用．

英文摘要：

In this paper, the synergic effect between 1, 4 - bis （3 - （dodecyloxylacyl） pyridinium） tutane） bromide （designated as NAE12 -4 -12） and sodium dodecyl benzene sulfate （SDBS）, polyacrylamide （PAM） polyaerylic acid （PAA） have been studied. The results show that there is good synergic effect between NAE12 -4 - 12 and SDBS at NAE12 -4 - 12 ：SDBS = 3：7. The cmc of the mixture of NAE12 -4 - 12 and SDBS is 0. 0031 mmol/L, which are two orders lower than that of NAE12 -4 - 12 solution free of SDBS. The value of-ycme reduces to 27.8 mN/m, which decreased by 44 mN/m compared with that of pure water. The critical aggregation concentrations of NAE12 -4 - 12 with PAM or PAA are higher than cme of NAE12 -4 - 12, and the γcat of mixture system is much lower than that of 0.01% PAM or PAA, suggesting that there is stronger interaction between NAE12 - 4- 12 and PAM/PPA.
