▎ 摘  要

NOVELTY - A hydrogel has three-dimensional matrix comprising carboxylated graphene oxide. USE - Hydrogel. ADVANTAGE - The graphene has complete shape, smoother surface and better elasticity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of hydrogel comprising preparing carboxylated graphene oxide, adding into water, ultrasonically treating, and dispersing in water at 80-120 degrees C for 24-96 hours to obtain carboxylated graphene oxide dispersion liquid.
