The invention relates to the field of hydrogel preparation, in particular to an ultra-long stretched self-healing hydrogel bonding material and a preparation method thereof. In order to solve the problems of poor stretchability of traditional hydrogel materials, difficult to achieve self-healing, and lack of bonding properties, the present invention adds a photoinitiator and a crosslinking agent to the mixed aqueous solution of acrylamide monomer and polyethyleneimine, and Curing of ultra-long stretched self-healing hydrogels by UV irradiation. The hydrogel has excellent ultra-long stretchability, self-healing property and adhesiveness. |
