▎ 摘　　要

NOVELTY - Preparing a highly elastic layered graphene oxide composition aerogel comprises (i) pretreating graphene oxide powder and cellulose nanofibril suspension to obtain a suspension of graphene oxide nanofibrils; (ii) adding powdered catalyst to the graphene oxide nanofibril suspension obtained in step (i) and dispersing to obtain a mixed suspension; (iii) adding solid hyperbranched polyacrylamide powder to the mixed suspension obtained in step (ii) and stirring at a system temperature to obtain a full reaction suspension; (iv) injecting the full-reaction suspension obtained in step (3) is into the mold, and using liquid nitrogen for directional freezing to obtain the frozen graphene oxide solid gel; and (v) freeze-drying graphene oxide solid gel. USE - The highly elastic layered graphene oxide composition aerogel is useful for catalyzing ozone in industrial wastewater treatment (claimed). ADVANTAGE - The highly elastic layered graphene oxide composition aerogel: uses graphene oxide and cellulose nanofibrils as the main raw materials to prepare the composition aerogel to ensure the applicability in this process; can prepare the graphene oxide composition aerogel with a layered structure, thus ensures that the high elasticity of the aerogel; uses high elasticity, environmentally-friendly ultra-molecular-weight chain polyacrylamide powder as a cross-linking agent, improves the strength of graphene oxide composition aerogel, and does not affect its elasticity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for highly elastic layered graphene oxide composition aerogel, is prepared by the preparation method.
