23 Jul Agar and graphene oxide double-network hydrogel and preparation method thereof
Abstract
The invention belongs to the technical field of intelligent high polymer materials, and discloses agar and graphene oxide double-network hydrogel and a preparation method thereof. The preparation method comprises the steps as follows: graphene oxide powder is ultrasonically dispersed in deionized water, and graphene oxide dispersion liquid is obtained; hydrogel monomers are then added, the mixture is stirred and uniformly dispersed under ice bath; nitrogen is introduced into for oxygen removal, agar is added, and the mixture is heated and stirred at a temperature of 85-95 DEG C to dissolve the agar; the mixture is cooled to the room temperature, an initiator is added, vibrated, injected into a mold and then put in a drying oven to react for 24-28 hours at a temperature of 40-60 DEG C, and the agar and graphene oxide double-network hydrogel is obtained. The hydrogel has relatively high tensile strength and elongation at break and good anti-fatigue performance and self-healing capacity, and can be applied to tissue engineering and artificial intelligence devices.
