液滴在固体表面上的附着力是影响液滴在固体表面上迁移的关键因素。尽管湿区域中的所有部分都有助于液滴的粘附，但大多数先前的粘附力模型都考虑了湿区域周边的长度。最近，作者提出了一种确定液滴在平坦固体表面上的粘附能的新方法，并使用疏水性固体表面上的各种液滴验证了这一概念。在这项研究中，进行了实验来验证新概念也可以应用于亲水表面。这些数据的实验测量和分析表明，单位面积粘附能的新定义适用于描述液体在亲水固体表面以及疏水固体表面上的运动。
The adhesion force of a liquid droplet on a solid surface is a key factor influencing mobility of liquid droplets on the solid surface. Most of previous adhesion force models consider the length of the periphery of the wet area even though all parts in the wet area contribute to the adhesion of a liquid droplet. Recently, the authors proposed a new method to determine the adhesion energy of a droplet on a flat solid surface and this concept was verified using various liquid droplets on a hydrophobic solid surface. In this study, experiments are performed to verify that the new concept also can be applied to hydrophilic surfaces. Experimental measurements and analysis of these data demonstrates that the new definition of adhesion energy per unit area is appropriate for describing the movement of a liquid on hydrophilic solid surfaces as well as hydrophobic solid surfaces.
