NOVELTY - Preparing chitosan/reducing graphene oxide gas gel comprises (1) mixing the graphene oxide and chitosan to obtain chitosan/graphene oxide solution, (2) adding the chitosan/graphene oxide solution in a hydrothermal reaction kettle; performing hydrothermal reaction at high temperature to obtain chitosan/reducing graphene oxide solution, (3) adding the chitosan/reducing graphene oxide solution in refrigerator for pre-freezing, freezing and drying to obtain chitosan/reducing graphene oxide aerogel. USE - The method is useful for preparing chitosan/reducing graphene oxide gas gel. ADVANTAGE - The method reduces graphene oxide by using hydrothermal reduction synergistic chitosan reduction, without adding additional reducing agent, avoids the damage to the experimental personnel and pollution to the environment; can save the preparation cost of reducing graphene oxide composite aerogel, utilizes hydrothermal reaction and freeze-drying method, short preparation process, simple operation, quickly and efficiently preparing chitosan/reducing graphene oxide gas gel, the shape of the aerogel is controllable and by selecting different mold to control the shape of the aerogel and the prepared aerogel has high strength and does not shrink.
