Careful investigation about dynamic adsorption properties of surfactant molecules has a tremendous interest for their practical applications. The intention of this article is to study the dynamic adsorption properties at air/water interface for 16 nonionic sugar-based surfactants with gradual structure variation. Based on obtained results the dynamic surface tension (DST) behaviour of glycolipids was found to depend on both hydrophobic chain length and bulk concentration of surfactant. Interestingly, the plot of the maximum rate of surface tension decrease against the surfactant bulk concentration showed a linear trend for all studied surfactants independently of their structure. Furthermore, it was confirmed that all molecules were gathered on one unique curve representing a plot of the limit elasticity versus the relative surface concentration of surfactant. The using approach provided further insight into the anticipation of the dynamic surface properties of sugar-based amphiphiles.

糖基表面活性剂的动态界面特性:实验研究和建模

仔细研究表面活性剂分子的动态吸附特性对其实际应用引起了极大的兴趣。本文旨在研究结构逐步变化的16种非离子型糖基表面活性剂在空气/水界面的动态吸附性能。根据获得的结果,发现糖脂的动态表面张力(DST)行为取决于疏水链长度和表面活性剂的总浓度。有趣的是,所有研究的表面活性剂的表面张力最大降低率相对于表面活性剂体积浓度的曲线均呈线性趋势,而与它们的结构无关。此外,证实所有分子都聚集在一条独特的曲线上,该曲线代表极限弹性与表面活性剂相对表面浓度的关系图。使用方法提供了对基于糖的两亲物的动态表面性质的预期的进一步洞察力。
