摘　　要：研究了不同连接基的琥珀酸酯磺酸盐型双子表面活性剂(GSS)与辛基苯基聚氧乙烯醚(TX-100)复配体系(GSS/TX-100)在水溶液中的表面性质和胶团化行为,对混合胶团和表面吸附层的组成和相互作用参数进行了计算。结果发现:复配体系水溶液在形成胶团和表面吸附时无明显甚至不存在正加和增效,但是TX-100的加入可明显降低GSS的临界胶束浓度,混合胶团中TX-100占胶团的主要成分,GSS与TX-100具有较弱的相互作用,连接基较短的GSS更易形成胶束,也更易与TX-100形成混合胶束。Surface properties and micellization behavior of Gemini sulfo-succinate sodium（GSS） and Triton X-100（TX-100） binary mixture in aqueous solution were investigated with various GSS spacer lengths. Compositions in mixture micelles and surface absorbance layer as well as interaction parameters between the two components were analyzed. Results showed that no obvious or maybe no presence of synergistic effect between GSS and TX-100 were found on surface property and micellization in aqueous solution, although TX-100 decreased apparently critical micelle concentration（cmc） of GSS and was major component in mixture micelles. GSS of shorter spacers was easier to form micelle itself and mixture micelle with TX-100. Spontaneous formation of mixture micelle and weak molecular interaction was observed in mixture of GSS362 and TX-100.
