| Research Abstract |
In this study, we investigated a new method to induce the adhesive force and debonding separation of hydrogels in response to environmental conditions. The effects of temperature and water content on the adhesion properties of thermoresponsive poly(N-isopropylacrylamide), poly(sodium acrylate), and poly(vinyl alcohol) hydrogels were extensively studied. We found that the adhesion between hydrogels can be controlled by changing the external conditions. The method is generic in any combination of a stimulus-responsive gel and its stimulus ; the adhesive force and debonding separation can be easily controlled only by adjusting an external stimulus.
