▎ 摘　　要

NOVELTY - An agar source graphene oxide double network hydrogel comprises agar natural polymer used as network (I) and graphene oxide cross-linked polymer used as network (II). USE - Agar source graphene oxide double network hydrogel used for tissue engineering applications and artificial intelligence device. ADVANTAGE - The hydrogel has high tensile strength and elongation rate, excellent fatigue resistance and self-healing capabilities. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation method of agar source graphene oxide double network hydrogel, which involves dispersing ultrasonic graphene oxide powder in deionized water, obtaining graphene oxide dispersion liquid, adding water to hydrogel monomer, ice-cooling, stirring, evenly dispersing oxygen and nitrogen, adding dispersion liquid to agar, heating at 85-95 degrees C, stirring to dissolve the agar, cooling the dispersion liquid to room temperature, adding initiator, injecting into the mold, placing into an oven, and drying at 40-60 degrees C for 24-48 hours.
