Fatigue-resistant hydrogel adhesion

linst06's picture

This is our recent work on the design of fatigue-resistant hydrogel adhesion. In this work, we show that fatigue-resistant hydrogel adhesion can be achieved by anchoring ordered nanocrystalline domains at the interface. This method is applicable to glass, ceramic, titanium, aluminum, stainless steel, and even elastomers including PU and PDMS. We also demonstrate its potential applications as endurant hydrogel coatings for versatile engineering materials with complex geometries.
