表面功能化在抗阻力、抗污染、防结冰、自清洁、可逆粘附、集水等方面具有重要的应用前景。最近，提出了一种新的功能表面技术，该技术可以激活液滴从嵌入在疏水表面的楔形亲水区域的窄端移动到宽端。本文进行了系统的分子动力学模拟和理论分析，以了解其运动机理，并进一步提出了更系统的高级功能表面设计。当液滴从楔形轨迹的窄端向宽端移动时，液滴的势能随距离不断减小，当液滴完全进入亲水区域时，相应的势能达到最小。亲水区楔角和液滴大小的影响。
Surface functionalization has important application prospects in many aspects, for example, anti-drag, anti-pollution, anti-icing, self-cleaning, reversible adhesion, water collection, and so forth. Recently, a new technique of functional surface was proposed, in which a droplet can be activated to move from the narrow end of a wedge-shaped hydrophilic region imbedded in a hydrophobic surface to the wide end. Systematic molecular dynamics (MD) simulations and theoretical analysis are carried out in this paper in order to understand the motion mechanism, and more systematic designs for advanced functional surfaces are further proposed. It is found that the potential energy of the droplet decreases continuously as a function of distance when the droplet moves from the narrow end of the wedge-shaped track to the wide end and the corresponding potential energy achieves the minimum when the droplet completely enters the hydrophilic region. Effects of the wedge angle of hydrophilic area and the size of the drop...
