Cohesive Behaviors of Hydrogel Under Large-Scale Bridging

It has been recently revealed that large-scale bridging mechanism can be invoked to drastically improve the debonding resistance of hydrogel adhesion, but the optimization of the improvement remains elusive. Aiming at shedding light on the optimization, the present article investigates the cohesive behaviors of hydrogel under the condition of large-scale bridging in 90-deg peel. A quasi-static model is established based on the principle of...
