▎ 摘　　要

NOVELTY - A cellulose-based magnetic gas gel material is prepared by formulating 0.01-10 wt.% aqueous graphene oxide solution, using graphene oxide and amphoteric cellulose at ratio of 1:10-10:1, stirring at 200-600 rpm to obtain amphoteric cellulose/graphene oxide binary composite liquid, ultrasonically dispersing ferroferric oxide in ethyl alcohol to obtain 0.1-10 wt.% ferroferric oxide ethyl alcohol solution, slowly adding ferroferric oxide ethyl alcohol solution, uniformly stirring to obtain ternary composite liquid, dropping aqueous crosslinking agent solution under stirring, and freeze-drying. USE - Preparation of cellulose-based magnetic gas gel material. ADVANTAGE - Product is low-cost, has high strength, characteristic, biological compatibility, loading ability, and surface activity and absorption capacity.
