N2 - This paper presents a study of bi-directional switchable adhesion of an organic microdroplet on dodecylbenzenesulfonate doped polypyrrole (PPy(DBS)) microstructures at ultra-low voltages (0.9 V) in an aqueous environment. The PPy(DBS) switched between an oxidized and a reduced state upon application of low voltages. The PPy(DBS) microstructure oxidized at 0.6 V behaved like a super sticky surface in regard to an organic droplet; in contrast, the PPy(DBS) microstructure reduced at-0.9 V was super slippery. Utilizing the tunable adhesion property of PPy(DBS) microstructures, we demonstrated a capture/release manipulation of an oil-based dichloromethane (DCM) microdroplet at a voltage of 0.9 V.
