It is demonstrated experimentally that the solution droplet behavior is governed by the co-occurrence of outward hydrodynamic and surface tension (solute Marangoni) induced flows. Potassium ferrocyanide allows the effective visualization of the processes taking place in the droplet. Wetting properties of the substrate govern the shape evolution of the evaporated droplet. Quantitative estimation of the wetting properties of textured polymer surface is presented.
实验表明，溶液液滴行为受向外的流体动力学和表面张力（溶质马兰戈尼）诱导流共同作用的支配。亚铁氰化钾能有效可视化液滴中发生的过程。基底的润湿性决定了蒸发液滴的形状演变。给出了纹理化聚合物表面润湿性的定量估计。
