Heterogeneous Wettability-Based Construction of Two-Phase Interfaces for Underwater Reversible Adhesion. [PDF]

Adv Sci (Weinh)
The design employs heterogeneous wettability surfaces that construct stable oil‐water interfaces to achieve robust and rapid reversible adhesion. Linear enhancement of adhesion strength is realized through multi‐interface patterning. This adhesive enables rapid on‐demand detachment within five seconds via voltage‐induced electrolysis, offering a level ...
