▎ 摘  要

NOVELTY - Method for rapidly preparing graphene fiber aerogel comprises performing the blow spinning on the graphene oxide-sodium polyacrylate mixed solution, spraying the gel fiber with vacuum degree of less than 0.1Pa and the temperature of more than 200 degrees C to obtain dried and shaped graphene oxide fiber aerogel. In the graphene oxide-sodium polyacrylate mixed solution, the ratio of the mass of graphene oxide and sodium polyacrylate is 1:1-3:1 and the molecular weight of the sodium polyacrylate is more than 3000. USE - The method is useful for rapidly preparing graphene fiber aerogel. ADVANTAGE - The method is simple and environmentally friendly and drastically reduces the surface vapor pressure of the water in the gel fiber. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the transposition of the preparation of graphene oxide fibers (Drawing includes non-English language text).
