A series of Triton surfactants with increasing number of ethylene oxide (EO) groups were applied to investigate thermal-driven surface flow. It was found that the thermal gradient is proportional to the number of EO groups on the surface. This correlation leads to the linear correlation between the surfactant structure and the driving force of the surface flow. The friction force, in contrast, follows a monotonic but nonlinear correlation with surfactant's EO groups. The results demonstrate the possibilities to manipulate the surface flow, with potential applications in multiple-phase systems.
一系列环氧乙烷（EO）基团数量不断增加的Triton表面活性剂被用于研究热驱动的表面流动。研究发现，热梯度与表面上EO基团的数量成正比。这种相关性导致了表面活性剂结构与表面流动驱动力之间的线性关系。相比之下，摩擦力与表面活性剂的EO基团呈现单调但非线性的关系。结果表明了操纵表面流动的可能性，在多相系统中具有潜在应用。
