We present that not only a droplet could move along given direction but also two droplets move away from one another on wettable gradient surfaces, which is fabricated by depositing copper particles into micro/nano--hierarchical structures via a one-step gradient electrodeposition method. More importantly, the movement distance could be precisely predicted by the force analysis and adjusted by the initial position of the droplet and/or the magnitude of the wettable gradient
