Abstract

This paper presents a reversible manipulation of a dichloromethane (DCM) droplet at low voltages. The mechanism is governed by the reduction-oxidation reaction (redox) of dodecylbenzenesulfonate-doped polypyrrole (PPy) film. The voltages ranging from -0.9V to 0.6V (vs. Ag/AgCl reference) was applied to PPy film to change its reduction and oxidation states to control the shape of DCM droplet. The redox reaction was performed in-situ, and the manipulation of a DCM droplet was monitored using a goniometer. The experimental result in this work shows that the DCM droplet spreads out without an observable change of contact angle, which disagrees with the typical wetting behavior of a liquid droplet.
