Abstract

The sliding behavior of the water droplets on the silicon surface treated by fluoroalkylsilane was directly observed. Water droplets elongated and contracted during sliding, and inversely corresponded to the change of sliding acceleration. Tilt angle and contact angle hysteresis affected this phenomenon. Lowering the difference in contact angle hysteresis between the pre-sliding state and the equilibrium state during sliding will be one of the approaches for suppressing this elastic motion.
