Abstract

The interactions of polyelectrolyte poly (sodium styrene sulfonate or NaPSS) and anionic surfactants, sodium glycodeoxycholate (SGDC) and sodium tetradecyl sulfate (STS), as well as their combination (SGDC + STS) at different mole fraction ratios, were investigated using surface tension analysis. In the SGDC + STS binary mixture, when the amount of NaPSS (0.005–0.03%) increased from \({\alpha }_{{\text{SGDC}}}\) 0.0 to 1.0, increasing the critical micellization concentration (cmc) of the mixtures. The minimum cmc values were found from 0.833 to 1.480 mmol L−1 in the presence of 0.03% of NaPSS. Clint, Rubingh, Motomura, and Rodenas approaches were used to evaluate the ideal cmc, activity coefficients (fi), interaction parameter (–β), micellar compositions (x), and ideal micellar composition of (xid) of SGDC + STS mixtures. Synergism has been demonstrated by the experimental values of c0m being lower than the ideal values in water. Moreover, by adding NaPSS from 0.005 to 0.03%, the synergism interaction was eliminated and antagonism behavior was developed. The standard Gibb’s free energy of micellization (\({\Delta G}_{m}^{0})\) and surface excess (Γ) and surface area per absorbed molecules (Amin) was decreased or increased depending on NaPSS amount in the SGDC + STS mixture with varying \({a}_{{\text{SGDC}}}\).

研究聚(苯乙烯磺酸钠)对甘脱氧胆酸钠和十四烷基硫酸钠混合胶束的影响
采用表面张力分析法研究了聚电解质聚(苯乙烯磺酸钠或 NaPSS)与阴离子表面活性剂糖脱氧胆酸钠(SGDC)和十四烷基硫酸钠(STS)以及它们在不同摩尔分数比下的组合(SGDC + STS)之间的相互作用。在 SGDC + STS 二元混合物中,当 NaPSS 的用量(0.005-0.03%)从 0.0 增加到 1.0 时,混合物的临界胶束化浓度(cmc)也随之增加。在 NaPSS 含量为 0.03% 的情况下,最小 cmc 值为 0.833 至 1.480 mmol L-1。Clint 法、Rubingh 法、Motomura 法和 Rodenas 法用于评估 SGDC + STS 混合物的理想 cmc、活性系数 (fi)、相互作用参数 (-β)、胶束成分 (x) 和理想胶束成分 (xid)。c0m 的实验值低于水中的理想值,这证明了协同作用。此外,通过添加 0.005% 至 0.03% 的 NaPSS,协同作用被消除,而出现了拮抗行为。标准吉布斯胶束化自由能(\({\Delta G}_{m}^{0})和表面过量(Γ)以及每个吸收分子的表面积(Amin)随着 NaPSS 在 SGDC + STS 混合物中的用量的变化而减小或增大。

期刊介绍: Colloid and Polymer Science - a leading international journal of longstanding tradition - is devoted to colloid and polymer science and its interdisciplinary interactions. As such, it responds to a demand which has lost none of its actuality as revealed in the trends of contemporary materials science.
