The behavior of water droplets on copper and aluminum surfaces has been examined in this work. This study reports a simple technique to move water droplets on hydrophobic copper surfaces containing a hydrophilic aluminum background. The copper is rendered hydrophobic using a self-assembled monolayer that has a higher selectivity for copper than aluminum. A surface tension gradient due to a wedge shape creates a significant net driving force which moves the droplet towards the end of the wedge that contains more aluminum surface area. Droplet motion has been observed on both horizontal surfaces and surfaces oriented vertically against gravity. It was found that the speed depends on both the head angle of the triangle and the contact angles on the aluminum and copper regions. The effects of surface patterning and oxidation of the metal on water droplet behavior were also studied as functions of time for smooth and rough surfaces.
