▎ 摘  要

NOVELTY - Preparing graphene oxide doped superabsorbent resin involves ultrasonically dispersing 0.04-0.05 g graphene oxide in 25-35 mL deionized water for 35-45 minutes to obtain uniformly dispersed graphene solution, which is added with 0.7-0.75 g carboxymethyl cellulose, stirred uniformly to obtain a transparent viscous solution, which is heated for 25-35 minutes at 58-62 degrees C under a nitrogen atmosphere, while maintaining the nitrogen bubbling. USE - Method for preparing graphene oxide doped superabsorbent resin (claimed). ADVANTAGE - The method enables to prepare graphene oxide doped superabsorbent resin, which is eco-friendly. DETAILED DESCRIPTION - Preparing graphene oxide doped superabsorbent resin involves ultrasonically dispersing 0.04-0.05 g graphene oxide in 25-35 mL deionized water for 35-45 minutes to obtain uniformly dispersed graphene solution, which is added with 0.7-0.75 g carboxymethyl cellulose, stirred uniformly to obtain a transparent viscous solution, which is heated for 25-35 minutes at 58-62 degrees C under a nitrogen atmosphere, while maintaining the nitrogen bubbling. The 0.004-0.005 g N,N'-methylenebisacrylamide is added to 7-8 g acrylic acid and ultrasonically dispersed for 20-50 minutes to obtain a homogeneous solution, which is added with transparent viscous solution, reacted at 68-72 degrees C for 2.5-3.5 hours under the protection of nitrogen, cooled, washed and dried to obtain the final product.
