摘　　要：通过表面张力及荧光探针方法,研究了癸基硫酸钠和癸烷磺酸钠与阳离子聚电解质聚二甲基二烯丙基氯化铵(PDMDAAC)的相互作用.结果表明,虽然单一癸基硫酸钠和癸烷磺酸钠性质非常相似,但它们与PDMDAAC的相互作用有明显差别,癸基硫酸盐与PDMDAAC的相互作用明显强于癸烷磺酸盐.通过量子化学计算结果对本文实验观测结果进行了解释.Interactions between the cationic polyelectrolyte polydimethyldiallylammonium chloride （PDMDAAC） and sodium decylsulfate as well as sodium decanesulfonate were investigated by surface tension and pyrene fluorescence spectroscopy techniques. We found that although many properties of sodium decylsulfate and sodium decanesulfonate are similar, there are striking differences in their interactions with PDMDAAC. Sodium decylsulfate interacts with PDMDAAC more strongly than sodium decanesulfonate does. The experimental results in this work were explained by the data of the quantum chemical calculation.
