摘要:We consider a charged droplet sitting on a dielectric substrate and study the static profile of the  interface near the contact line. We first derive the governing equations using the principle of minimum energy, then discuss the distinguished limit of the model. Analysis of the inner problem, which governs the interface profile near the contact line, shows the existence of a well-defined apparent contact angle. The apparent contact angle depends on the applied voltage and the thickness of the dielectric substrate, and the relation agrees well with the empirical Young-Lippmann equation.
