Sliding mode transition of water droplet on the silicon surface coated with octadecyltrichlorosilane
The sliding acceleration of a water droplet on a silicon surface treated with octadecyltrichlorosilane was evaluated by changing the droplet weight. All water droplets slide down with a constant sliding acceleration. The slope of the sliding acceleration against the droplet weight was changed at 20 mg, suggesting that the dominant sliding mode was shifted from slipping to rolling.
