Functional hydrogel with highly stretchable, self-healable, and adhesive co-polymeric gel (PAA-PMMA gel) was synthesized from the immiscible acrylic acid (AA) and methyl methacrylate (MMA). The self-healing property is triggered by the hydrophobic interaction, as well as the breakdown and reformation of sacrificial noncovalent crosslinking through the weak hydrogen bonds. The gel shows simultaneously improved energy dissipation and excellent adhesiveness to the surfaces of polystyrene, glass, wood, metal, stone, ceramics, skins. Furthermore, the calcium phosphate mineralization yielded a hydrogel with enhancement of MC3T3 cell adhesion and proliferation. Overall, the PAA-PMMA gel could employed for diverse applications based on the synthesis parameters.
