Tough thermosensitive hydrogel with excellent adhesion to low-energy surface developed via nanoparticle-induced dynamic crosslinking

Stimuli-responsive adhesive hydrogels have obtained increasing attention due to their applications in drug delivery and wearable sensors. However, these hydrogels exhibit weak mechanical properties and poor adhesion, especially on low-energy surfaces. Here, a temperature-responsive adhesive hydrogel was developed based on mussel-inspired dopamine chemistry and core–shell nanoparticle-regulated dynamic cross-linking. Poly(N-isopropylacrylamide)...
