This research demonstrates that at the hydrophilic interface, the contact angle formed between the droplet and the interface is small (θ ≤ 61.3°), and when the collision occurs, the effective contact area is small, which cannot form a larger obstruction to the forward motion of the marble and ends the collision with the droplet in the form of overturning; when the hydrophobic interface is changed into the hydrophobic interface, the effective collision area increases, which forms a larger obstruction to the forward motion of the marble and replaces overturning with rebound behavior; when the hydrophobicity of the interface increases to θ = 124.5°, the effective collision area becomes larger, and the fluctuations generated at the interface after the collision cause the particles on the surface of the marble to migrate and appear in the exposed area, forming a liquid bridge and then quickly completing the aggregation. When marbles and sessile droplets collide, three distinct motion behaviors emerge: climbing, rebound, and coalescence-merging (coalescence)."> - 必威体育下载
