▎ 摘　　要

NOVELTY - Preparing controllable three-dimensional reduced graphene oxide aerogel involves dispersing the oxidized graphene deionized water to prepare an aqueous solution for oxidizing graphene, adjusting the pH value to 8-13, stirring uniformly, adding hydrazine hydrate to the graphene water solution, fully stirring and ultrasonically processing for 20-30 hours at room temperature to obtain a graphene hydrogel, freezing the 3D-reduced graphene oxide for 4-12 hours, taking it out and naturally dry to room temperature for 24-48 hours to obtain the final product. USE - Method for preparing controllable three-dimensional reduced graphene oxide aerogel. ADVANTAGE - The method is simple, A high-efficient and universal method preparation three-dimensionally reducing and oxidizing (graphene 3D-RGO) gas gel. The method has simple operation, the reaction condition is easy to control, it is suitable for mass production, and has excellent cyclic compression stability and conductivity, with outstanding technical advantages. DESCRIPTION OF DRAWING(S) - The drawing shows a gas gel obtained according to different types of reaction container preparation.
