Abstract

Surface droplets in the microscale are of great interest for their relevance in broad droplet-based technologies. Derived from the Ouzo effect, the solvent exchange process is a simple bottom-up approach to produce surface nano-/micro-droplets by the nucleation and growth mechanism. The oil oversaturation pulse is created as a good solvent (ethanol) for the oil displaced by a poor solvent (water) in the flow cell. In this work, we investigated the formation of surface droplets on a one-dimensional substrate (a single hydrophobic fiber with a diameter of 10 μm) in a flow. The droplet growth on the microfiber is enhanced as the fiber is perpendicular to the external flow direction, due to the ..
