Effects of Electric Field on Propulsion Characteristics of Self-motion Using Chemical Marangoni Effect

Abstract

This paper presents a control of propulsion force of a self-motion on liquid using chemical Marangoni effect by applying electric field to the liquid surface. We used imidazolium ionic liquids as surface active materials to induce Marangoni effect for propelling a locomotor. It was confirmed that the propulsion force of the locomotor was reduced by applying the electric field to the aqueous surface where the ionic liquid was expelled from the locomotor.
