Effective three-dimensional superhydrophobic aerogel-coated channel for high efficiency water-droplet transport

Three-dimensional superhydrophobic surfaces have been used effectively to optimize droplet transport efficiency in diverse fluidic systems. However, the fabrication methods for superhydrophobic surfaces applicable to fluidic devices usually involve complicated process. Herein, we report a simple but...

description Three-dimensional superhydrophobic surfaces have been used effectively to optimize droplet transport efficiency in diverse fluidic systems. However, the fabrication methods for superhydrophobic surfaces applicable to fluidic devices usually involve complicated process. Herein, we report a simple but effective method of fabricating a superhydrophobic surface using organically modified silica aerogel. Superhydrophobic aerogel thin film having highly porous micro/nanostructured surface with methyl groups was realized inside a 3D channel by coating it. To demonstrate that the aerogel-coated surface effectively facilitates movement of water droplets, the droplet-based flow characteristics regarding the triple line were conducted.
