Study on wetting control of fluid systems under electric field

本研究的目的是阐明电润湿的行为，这是在电场下的润湿现象。为了避免固体表面粗糙度和不均匀性问题，选择由三种流体组成的微乳液作为实验体系。此外，从导电性的观点来看，微乳液中的三种流体中的至少一种包含具有高导电性的离子液体。通过测量接触角的方法研究了电场作用下液滴的润湿性。

The aim of this study is to clarify the behavior of electrowetting, which is wetting phenomena under an electric field. In order to avoid the problems of roughness and inhomogeneity on solid surface, the microemulsion composed of three fluids was chosen as an experimental system. From the standpoint of conductivity, furthermore, at least one of three fluids in microemulsion contains an ionic liquid having high conductivity. We investigated the wettability of liquid drop under an electric field by measuring the contact angle.
