Abstract
Stimuli-responsive adhesives have significantly transformed the field of structural bonding applications. This work offers a thorough examination of the rapidly developing field of debondable adhesives, which show reversible adhesion in response to certain chemical or physical stimuli. A thorough examination of numerous categories driven by stimuli such as pH, light, moisture, and temperature is given. Exploring environmentally sustainable solutions has been made possible by recent developments in material design and synthesis processes, which have unlocked new debondable platforms. Notably, pH-responsive adhesives have garnered significant interest due to their diverse uses in biomedical, consumer, and industrial domains. A thorough investigation of the complex mechanisms governing acid/base-mediated adhesion is presented through the evaluation of reactive components and engineering concepts. An analysis is conducted on the current literature that explains the principles of pH activation. Additionally, this discussion explores potential opportunities for these innovative adhesives, including the expansion of functionality and the ability to achieve more precise control over debonding properties. These prospects have the potential to greatly enhance the range of applications for these adhesives.
