Understanding microscale water droplet behavior on a hydrophobic surface with fine structure is important to achieve higher hydrophobic efficiency. Nevertheless, observing details of microscale water droplets and fine structures on a surface is difficult using traditional analytical methods.
Recently, we observed a water droplet using the wet cover method: a new observation technique using scanning electron microscopy. This report explains the principle of the wet cover method and the use of this method for dynamic observation of liquid droplets of several types, such as water on a substrate.
