Abstract
Reversible surface adhesion transitions are induced by controlling polar interactions at liquid-liquid interfaces and assessed using contact angle hysteresis (Δθ). The switchable oil adhesion is attributed to the decrease in the liquid-liquid interfacial tension from Lewis acid-base interactions at the oil-water interface. Thus, the polar interactions changed the contact state. This study provides a novel strategy for adhesion control, and may inspire scientists working on liquid transport involving oil/water/solid triphase systems and bioadhesion regulation under water.
