概要

• 論文の詳細を見る

• We report a simple method that allows facile evaluation of the driving force required to move a droplet settled on a boundary of two surfaces with different surface energies. In the method, a vertically placed sample substrate holding a droplet is gradually recovered to the horizontal state, so that the driving force of the self-directed movement can be obtained from the counterbalancing gravitational force exerted on the droplet at the critical tilt angle at which the droplet starts to move.
