Interactions among the oppositely charged polymer and surfactant are significantly complex in comparison to the interaction between an ionic surfactant and nonionic polymer vis-à-vis the physicochemical properties of the resulting polymer–surfactant solutions. In this work, we have deliberated upon the interactions taking place in between a water-soluble anionic polymer, sodium alginate (SA), with a cationic amphiphile, hexadecylbenzyldimethylammonium chloride (C₁₆BzCl), in absence and in presence of sodiumchloride (NaCl) and sodium salicylate (NaSl) employing tensiometric, conductometric, and rheometric measurements. The system was characterized by evaluating physicochemical properties like viscosity curves, critical aggregation concentration (cac), and critical micelle concentration (cmc) as a function of C₁₆BzCl concentration. The results show significant differences between the ions furnished by NaCl and NaS1 which could be justified on the basis of effect of solubilization, differential binding of NaSl to polymeric backbone, electrolyte effect, and the solvent modifying tendencies in contrast to the only salt effect of NaCl.

氯化钠和水杨酸钠中的离子对藻酸钠与C 16 BzCl之间相互作用的调节：疏水盐对阴离子聚合物-阳离子表面活性剂相互作用的影响的认识

与离子表面活性剂和非离子聚合物之间的相互作用相比，带相反电荷的聚合物与表面活性剂之间的相互作用相对于所形成的聚合物-表面活性剂溶液的物理化学性质而言非常复杂。在这项工作中，我们研究了在不存在和存在氯化钠（NaCl）的情况下，水溶性阴离子聚合物海藻酸钠（SA）与阳离子两亲物，十六烷基苄基二甲基氯化铵（C ₁₆ BzCl）之间发生的相互作用。和水杨酸钠（NaSl）采用拉力法，电导法和流变法测量。该系统通过评估物理化学性质（如粘度曲线，临界聚集浓度（cac）和临界胶束浓度（cmc））作为C的函数进行表征浓度为₁₆ BzCl。结果表明，NaCl和NaS1提供的离子之间存在显着差异，这可以根据增溶作用，NaSl与聚合物主链的差异结合，电解质效应和溶剂改性趋势来证明，这与NaCl唯一的盐效应相反。
