ABSTRACT

The influence of surface structures on the wettability and evaporation of a heated water drop is investigated both in the presence of a graphene layer and without a graphene coating. Different topology of surface roughness changes the structuring of water near nano-micro textures. The structured wall surface changes both the wettability and the evaporation rate. Molecular dynamics modeling has shown that by changing the geometric parameters of textures on the copper surface, it is possible to effectively control the wettability of a graphene coating. The calculation results correlate with the experimental data on the droplet contact angle.

加热结构表面石墨烯润湿性的分子动力学模拟和实验数据

摘要

研究了在存在石墨烯层和不存在石墨烯涂层的情况下表面结构对加热水滴的润湿性和蒸发的影响。表面粗糙度的不同拓扑改变了纳米微米纹理附近​​的水的结构。结构化壁表面改变了润湿性和蒸发速率。分子动力学建模表明，通过改变铜表面纹理的几何参数，可以有效控制石墨烯涂层的润湿性。计算结果与液滴接触角的实验数据相关。
