Thermally-Induced Gelation and Degelation in Adhesive Hydrogel Systems

Adhesive hydrogel systems exhibit fascinating temperature-driven phase changes. These versatile materials can transition between a liquid and a solid state depending on the surrounding temperature. This phenomenon, known as gelation and reverse degelation, arises from changes in the non-covalent interactions within the hydrogel network. As the temperature rises, these interactions weaken, leading to a fluid state. Conversely, upon lowering the temperature, the interactions strengthen, resulting in a rigid structure. This reversible behavior makes adhesive hydrogels highly versatile for applications in fields such as wound dressing, drug delivery, and tissue engineering.

Furthermore, the adhesive properties of these hydrogels are often enhanced by the gelation process.
This is due to the increased surface contact between the hydrogel and the substrate.
