The influence of molecular interactions on the adsorption and wetting of binary mixtures was studied by molecular dynamics simulations of sessile droplets on planar walls. The results provide insights into the competing effects between the fluid− fluid interactions and the solid−fluid interactions on the adsorption and wetting of mixtures. All interactions were modeled by the Lennard-Jones truncated−shifted (LJTS) potential. The influence of the different dispersive interactions in the fluid mixture as well as those between the fluid components and the wall on the gas and liquid adsorption, the three-phase contact, and the contact angle was determined. For the fluid mixtures studied in the present work, the phase behavior and the vapor−liquid interfacial properties are known from recent studies. Together with the present results, this provides a comprehensive picture of the influence of different molecular interactions on the closely related phenomena of wetting and adsorption in mixtures.

The sliding behavior of droplets on smooth and rough surfaces with various surface wettabilities is investigated by many-body dissipative particle dynamics simulations. On a smooth surface, as the driving force (Bo) increases, the droplet shape and velocity (Cac) before breakage can be classified into four distinct regimes: (I) nearly spherical cap with Cac∝Bo; (II) oval shape with negative deviation from the linear relation; (III) elongated shape without a neck, where Cac decreases with increasing Bo; and (IV) oscillation of an elongated shape with fluctuating sliding velocity. On rough surfaces, corner-shaped droplets, which are absent on a smooth surface, can be observed. A further increase in Bo leads to the formation of cusp and pearling. Different from pinching-off on rough surfaces, which produces a cascade of smaller droplets through groove-induced shedding, chaotic breakage of a droplet on a smooth surface is caused by an unsteady flow field. Finally, a universal linear relationship between the sliding velocity based on the surface velocity (Cas) and the modified driving force (Bo**) is derived to take into account the effects of surface wettability and roughness.
