Abstract

The sliding behavior of water droplets sandwiched between Si plates treated by octadecyltrimethoxysilane (ODS) and fluoroalkylsilane (FAS) was observed by changing the plate's distance (D) and droplet mass (m). The sliding angle depended on D and m and the upper and bottom combination of surface. The internal fluidity of the sliding droplet was observed by particle image velocimetry method with the high-speed camera system. The molecular length of silane and its flexibility can affect affinity with water and the hydrodynamics at the interface.
