Influence of a motion induced dynamic adsorption layer (DAL) at a liquid/air interface on a kinetic of three-phase contact line (TPCL) expansion in solutions of n-cetyltrimethylammonium bromide (CTAB - cationic surfactant) was studied. It was found that, independently of the solid surface hydrophobicity (assessed using determination of the receding contact angle values), the DAL presence influences profoundly the velocity of the TPCL expansion. For the quartz surface, where the contact angle was controlled by a CTAB concentration, the TPCL expansion rate correlateds with the degree of solid surface hydrophobicity. However, for similar values of the contact angle, much higher rate of the TPCL rate expansion was observed for the fully formed DAL at the colliding bubble surface. This effect was the most pronounced for receding contact angle equal to ca. 60–70° (i.e. for higher CTAB bulk concentrations). In the case of the highly hydrophobic poly(tetrafluoroethylene) (PTFE) surface, similar observations were reported, despite the fact that the receding contact angle values were independent of the CTAB bulk concentration. For the PTFE surface, additionally, similar TPCL expansion velocities were reported for pure water and CTAB solutions where the DAL structure was fully formed at the colliding bubble interface, suggesting similar liquid/gas interface’s hydrodynamic boundary conditions.

研究了液/气界面处的运动诱导动态吸附层（DAL）对正十六烷基三甲基溴化铵（CTAB-阳离子表面活性剂）溶液中三相接触线（TPCL）膨胀动力学的影响。已发现，与固体表面疏水性（通过确定后退接触角值进行评估）无关，DAL的存在对TPCL膨胀的速度产生了深远的影响。对于接触角由CTAB浓度控制的石英表面，TPCL膨胀率与s具有固体表面疏水性的程度。然而，对于相似的接触角值，在完全碰撞的气泡表面处，对于完全形成的DAL，观察到更高的TPCL速率膨胀率。当接触角等于ca时，此效应最为明显。60–70°（即较高的CTAB总体浓度）。在高度疏水的聚四氟乙烯（PTFE）表面的情况下，尽管后退接触角值与CTAB体积浓度无关，但也有类似的报道。此外，对于PTFE表面，据报道纯水和CTAB溶液的TPCL膨胀速度相似，其中DAL结构在碰撞气泡界面处完全形成，表明类似的液/气界面的流体动力学边界条件。
