The invention discloses a preparation method of tough and transparent hydrogel based on cellulose self-assembly regulation and control, and belongs to the technical field of hydrogel preparation. Dissolving cellulose in ionic liquid, and heating and dissolving to obtain a cellulose-ionic liquid solution; carrying out water-induced self-assembly on the cellulose solution to obtain cellulose gel; and soaking the cellulose gel in an acrylamide solution containing a photoinitiator for treatment, and then initiating polymerization by ultraviolet irradiation to obtain the tough and transparent hydrogel. According to the invention, the self-assembly action of the water-induced cellulose is adopted, so that the mechanical property of the hydrogel can be regulated, the problem that the strength, the stretching and the toughness cannot be considered in the traditional hydrogel reinforcing and toughening strategy is solved, and the hydrogel has good mechanical property and conductivity due to the existence of the ionic liquid in the system, and is expected to be used in the fields of flexible wearable equipment and the like. |
