Abstract
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.
