Abstract

The persistant droplet motion in liquid-liquid dewetting was discussed. It was found that the droplet continued to move in all direction of the dewetting front for extended periods with an initial droplet velocity varying linearly with the droplet size. It was observed that the persistant motion was due to a transient surface tension gradient on the substrate liquid surface trailing the dewetting front. A model to calculate the absolute values of the spontaneous droplet displacement and its variation with time was also presented.
