▎ 摘　　要

NOVELTY - A graphene oxide nanocomposite organic hydrogel comprises (in wt.%) graphene oxide (0.1-1.5), organic monomer (5-17), initiator (0.4-0.9), catalyst (0.1-0.3), and water (remainder). The organic monomer is acrylamide, acrylic acid, and/or N-isopropyl acrylamide. USE - Graphene oxide nanocomposite organic hydrogel. ADVANTAGE - The graphene oxide nanocomposite organic hydrogel comprises graphene oxide having a similar lamellar structure as that of lithium diatomite. The surface of graphene oxide contains hydroxyl and carboxyl functional groups. The hydrogel can be easily combined with acrylic acid, acrylic acid amide, and water. The hydrogel has excellent strength and mechanical property, and solves problems of lithium diatomite system with respect to usage of ionic monomer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene oxide nanocomposite organic hydrogel, which involves adding graphene oxide to deionized water, ultrasonically dispersing uniformly, adding organic monomer, stirring uniformly, removing oxygen, adding initiator and catalyst, and reacting at 10-30 degrees C for 48 hours.
