Effect of potential on spreading and detachment of organic droplets at aqueous metalic interface
The phenomena of electrowetting and recent application of electrical potential to shape organic microdroplets at solid substrates into arrays of lenses, with focal length that can be reversibly changed, point out to the importance of a general understanding of dynamics and equillibria of wetting processes at electrodes. We shall use simple videorecordings to demonstrate how spreading and shape of organic droplets at the mercury/aqueous electrolyte interface depend on the interfacial forces that are controlled by the applied potential. We indicate a method to measure interfacial forces in the system organic droplet-mercury electrode/aqueous electrolyte solution when adhesion counteracts buoyancy of a droplet. The significance of this work is that the wetting phenomena identified in the model system apply more generally, for the droplets and insoluble films on the electrode material, and the findings can be extrapolated to complex electrochemical systems of technological importance.
