Abstract
En 中文
Reversible adhesion of soft materials is crucial for the reconfiguration and reparation of soft devices. It remains challenging to achieve robust reversible adhesion over diverse substrates, including surfaces contaminated with moisture and oil. Here inspired by tree frogs that secrete mucus with surfactants to achieve good wetting over diverse dry and wet substrates, we explore a novel mechanism, osmocapillary adhesion, to use interfacial liquid modified by surfactants to achieve robust and reversible adhesion over diverse substrates. We show that osmocapillary adhesives greatly outperform conventional pressure-sensitive adhesives over low-surface-energy, moist, oily, and greasy substrates while achieving similar performance on high-surface-energy substrates.
