| titleOfInvention | Double-network hydrogel and preparation method thereof |
| abstract | The invention discloses a preparation method of a double-network hydrogel, which comprises the following steps: (1) mixing a first network monomer, glycerol, a cross-linking agent, a photoinitiator and water to prepare a first mixed solution, and reacting under the illumination condition to prepare single-network hydrogel; (2) and (2) mixing a second network monomer, glycerol, a cross-linking agent, a photoinitiator and water to prepare a second mixed solution, soaking the single-network hydrogel in the second mixed solution, and reacting under the illumination condition to prepare the double-network hydrogel. The invention is based on free radical polymerization, adopts a two-step preparation method, uses ultraviolet light to irradiate and initiate reaction, has simple operation, can bear larger deformation and stress, and can still keep good use condition at minus 25 to 50 ℃; in addition, the hydrogel is placed at room temperature for more than 20 days, the water content is not obviously reduced, and the moisture retention is good. |
