| titleOfInvention | Preparation method of self-repairing hydrogel |
| abstract | The invention discloses a preparation method of self-repairing hydrogel, which comprises the following steps: s1, preparing an aqueous solution of the alkalinity regulator shown as the formula 1; s2, adding a hydroxyl donor, a photoinitiator and a boric acid body shown in the formula 2 into the aqueous solution of the alkalinity regulator, and fully dissolving to obtain a mixed solution; s3, removing air in the mixed solution in a vacuum environment, and bubbling inert gas to obtain a reaction solution; and S4, placing the reaction solution under ultraviolet irradiation or heating for random copolymerization to obtain the self-repairing hydrogel. The alkalinity regulator of the preparation method can regulate pH, can perform random copolymerization reaction with a hydroxyl donor with a specific structure through a carbon-carbon double bond, and then reacts with borate in a borate to form dynamic reversible crosslinking, so that the obtained self-repairing hydrogel realizes self-repairing performance under the room temperature condition without external stimulation; and the preparation method is simple. |
